Previous to the year 1871 few observations had been made in Belgium for determining the elements of terrestrial magnetism, if we except the series which has been carried on without interruption at the Royal Observatory since 1828. Before this latter date the Intensity and Dip had never been ascertained, and there existed only two reliable measures of the Declination, viz. that of 20°35'·5 for Ostend, which Pigot observed in 1772, and the other for Nieuport, which, at about the same date, was found by Mann to be 19°48'·5. Since 1828 the observations made at any other station besides Brussels have not been numerous. In 1854 the Dip was measured at Antwerp, Courtray, Ghent, Mons, and Ostend; the Horizontal Force was found at Liége and Louvain in 1829, 1850, and 1854, and also at Namur in 1829; and the three elements were observed in 1859 at Ghent and Mechlin. The results of these various observations are collected in the work entitled “La Physique du Globe,” by M. A. Quetelet, and in Dr. Lamont’s 'Untersuchungen über die Richtung und Stärke des Erdmagnetismus in Belgien,’ &c. The above being the only determinations of the magnetic elements, there is an obvious want of a complete series of observations at a sufficient number of stations, and the survey which forms the subject of the present paper was undertaken with the view of supplying the required series of connected values of the three elements. The instruments employed in this survey were the Barrow dip-circle, the Jones unifilar, and the Frodsham chronometer of Stonyhurst Observatory, and an excellent theodolite by Troughton and Simms for determining the azimuth of the fixed points for the Declination. For this last instrument I was indebted to the kindness of James Shoolbred, Esq., C. E. All necessary information respecting the magnets and instruments will be found in the paper on the Magnetic Survey of the West of France printed in the Phil. Trans, of 1870.

The rise of Islamist groups in Egypt's polity and society is given force through the articulation of a set of competing yet inter-linked discourses that challenge the authority of the post-independence secular nationalist discourse and attempt to reconstitute the field of struggle and domination in religious terms. Concurrently, these discourses seek authoritative status over the scope of meanings related to questions of identity, history, and the place of Islam in the world. The interpretations and definitions elaborated in reference to these questions by radical Islamist forces (the jihad groups and other militant Islamist elements) are often seen to dominate the entire field of meaning. However, claims to authority over issues of government, morality, identity, and Islam's relationship to the West are also made in and through a discourse that can appropriately be labeled “conservative Islamist.” The discourse and political role of conservative Islamism are the subject of this article.

In the Philosophical Transactions for 1826, Part II. Mr. Herschel has given a detailed account of observations, which were made in the month of July, 1825, for the purpose of ascertaining the difference of the meridians of the Royal Observatories of Greenwich and Paris, with a computation of these observations, from which the most probable value of the difference of longitude appears to be 9 m 21 s. 6. But I have perceived that in the copy of the observations delivered to him from the Royal Observatory of Greenwich, an error of one second has been committed; as the true sidereal time of the observation made there on 21st July, ought to be 17 h 38 m 57·12 in place of 17 h 38 m 56 s. 10, set down in the Table p. 104, which he informs me was computed at the Observatory, and officially communicated to him from the Astronomer Royal. This error seems to have had its origin in the little Table at the bottom of page 103; for, on subtracting the error of the clock, 47 s. 37, from the time 18 h 8 m 30 s. 40, the true sidereal time is 18 h 7 m 43 s. 03, instead of 18 h 7 m 42 s. 03, there given. The error in the result of that day’s observations, arising from this cause, has been partly compensated by a mistake of three tenths of a second, which has occurred in calculating the combined observations of the same day, the gain of mean on sidereal time being stated to be — 4 s. 54 (pp. 120 and 122), in place of — 4 s. 24. On checking the other observations, a few trifling alterations appear to be necessary upon the Greenwich Table of sidereal time, from the data given along with it. These seem to be occasioned by different methods of calculation, and indeed are hardly worthy of notice. The French astronomers not having given the data on which the calculations of the sidereal times at Paris are founded, they are assumed to be correct.

Much literature on the cultural industries celebrates ethnicity as a source of creativity. Despite its positive connotation, this discourse reduces ethnic minority creatives to manifestations of a collective ethnic identity automatically leading to creativity, creating a paradox of creativity without a creative subject. Approaching creatives with an ethnic minority background as agents, this article investigates how they self-reflectively and purposely discursively construct ethnicity as a source of creativity in their identity work. Empirically, we analyze interviews with well-established creatives with an ethnic minority background active in Belgium. Most respondents construct their ethnic background as ‘hybrid’, ‘exotic’, or ‘liminal’ to craft an identity as creatives and claim creativity for their work. Only few refuse to discursively deploy ethnicity as a source of creativity, crafting more individualized identities as creatives. Our study contributes to the literature on power and ethnicity in the creative industries by documenting ethnic minority creatives’ discursive micro-struggle over what is creative work and who qualifies as a creative. Specifically, we show their counterpolitics of representation of ethnicity in the creative industries through the re-signification of the relation between the ‘west’ and the ‘other’ in less disadvantageous terms. Despite such re-signification, the continued relevance of the discourse of ethnicity as a key marker of difference suggests that ethnicity remains a principle of unequal organization of the creative industries.

I have for some time entertained an opinion, in common with some others who have turned their attention tot he subject, that a good series of observations with a Water-Barometer, accurately constructed, might throw some light upon several important points of physical science: amongst others, upon the tides of the atmosphere; the horary oscillations of the counterpoising column; the ascending and descending rate of its greater oscillations; and the tension of vapour at different atmospheric temperatures. I have sought in vain in various scientific works, and in the Transactions of Philosophical Societies, for the record of any such observations, or for a description of an instrument calculated to afford the required information with anything approaching to precision. In the first volume of the History of the French Academy of Sciences, a cursory reference is made, in the following words, to some experiments of M. Mariotte upon the subject, of which no particulars appear to have been preserved. “Le même M. Mariotte fit aussi à l’observatoire des experiences sur le baromètre ordinaire à mercure comparé au baromètre à eau. Dans l’un le mercure s’eléva à 28 polices, et dans Fautre l’eau fut a 31 pieds Cequi donne le rapport du mercure à l’eau de 13½ à 1.” Histoire de I'Acadérmie, tom. i. p. 234. It also appears that Otto Guricke constructed a philosophical toy for the amusement of himself and friends, upon the principle of the water-barometer; but the column of water probably in this, as in all the other instances which I have met with, was raised by the imperfect rarefaction of the air in the tube above it, or by filling with water a metallic tube, of sufficient length, cemented to a glass one at its upper extremity, and fitted with a stop-cock at each end; so that when full the upper one might be closed and the lower opened, when the water would fall till it afforded an equipoise to the pressure of the atmo­sphere. The imperfections of such an instrument, it is quite clear, would render it totally unfit for the delicate investigations required in the present state of science; as, to render the observations of any value, it is absolutely necessary that the water should be thoroughly purged of air, by boiling, and its insinuation or reabsorption effectually guarded against. I was convinced that the only chance of securing these two necessary ends, was to form the whole length of tube of one piece of glass, and to boil the water in it, as is done with mercury in the common barometer. The practical difficulties which opposed themselves to such a construction long appeared to me insurmount­able; but I at length contrived a plan for the purpose, which, having been honoured with the approval of the late Meteorological Committee of this Society, was ordered to be carried into execution by the President and Council.

Spaces are conditioned by social conditions; on the other hand, social structure is affected by spaces. Arcades, the subject of this article, first appeared in Europe in the 18th century as a result of an increase in trading activities. The arcades in Ankara, which were started to be built in the 1950s together with increasing trading activities, contributed to the urban economy with intense activities of shopping, re-determined social and urban relations as essential places of everyday life and became distinctive urban buildings with their original building typologies and the function of maintaining public continuity in the area of private ownership. Aim: This study aims to study the process in which passages emerged and to analyze their spatial features and, in particular, to examine the spatial formation of the distinctive passages in Ankara on the basis of their causation. Method: In the article, spatial features of the passages in the West were mentioned, and the conditions of the period in which the passages in Ankara were built were briefly explained. Spatial analysis of the passages found in the research area were conducted, and the formation of these passages were analyzed together with their reasons. Results: Of the 31 arcades in Ankara, 27 were built between 1950 and 1980 on and around the Atatürk Boulevard in Yenişehir/Kizilay. As of the mid-1950s, new planning decisions which were made one after the other in the built-up area re-shaped the Boulevard and its surrounding as the existing buildings were demolished, allowing to construct new buildings with arcades or stores in their entrances. Their interior designs and connections to the streets are different from the arcades in the West. Conclusion: The present subdivision system and new planning decisions applied in property order shaped the passages which were peculiar to Ankara.

The influence of lithium on the amphibian egg has been the subject of a number of investigations. From the work of Lehmann (1937), Töndury (1938), and Pasteels (1945) it is known that exposure of amphibian embryos to lithium results in a progressive cranio-caudal reduction of the central nervous system and a simultaneous conversion of the presumptive notochord into somites. Whereas these experiments were made with whole embryos, attempts have been made in recent years to localize the lithium effect by transplanting or explanting specific parts of the embryo. Gallera (1949), for instance, concluded from his experiments with transplants containing lithium treated presumptive chorda mesoderm, that lithium had reduced the ‘morphogenetic potential’ of this inductor. Lombard (1952), on the other hand, claimed that the susceptibility of amphibian eggs towards lithium was the result of the ion's direct influence on the ectoderm rather than on the presumptive archenteron roof.

The Way

The Roman Ermine Street, having crossed the Humber on the way to York from Lincoln, leaves Brough Haven on its west side, and the little town of Petuaria to the east. For the first half-mile northwards from the Haven its course is not certainly known: then, followed by the modern road, it runs northwards through South Cave towards Market Weighton. In the area thus traversed by the Roman road burials of the Roman age have already been noted in sufficient quantity to suggest an extensive cemetery. The interment which is the subject of the present note was found on 10th October 1936, when men laying pipes at right angles to the modern road, in the carriage-drive of Mr. J. G. Southam, having cut through some 4 ft. of blown sand, came upon a mass of mixed Roman pottery, dating from the late first to the fourth century A.D. Bones of pig, dog, sheep, and ox were also represented. Presently, at a depth of about 5 ft., something attracted closer attention. A layer of thin limestone slabs was found, covering two human skeletons, one lying a few feet from the west margin of the modern road, the other parallel with the road and some 8 ft. from its edge. The objects described below were found with the second skeleton, and the first to be discovered was submitted by Mr. Southam to Mr. T. Sheppard, F.S.A.Scot., Director of the Hull Museums, who visited the site with his staff. All that can be recorded of the circumstances of the discovery is contained in the observations then made, under difficult conditions. ‘Slabs of hard limestone’, it was reported, ‘taken from a local quarry of millepore oolite and forming the original Roman road, were distinctly visible beneath the present roadway—one of the few points where the precise site of the old road has been located. On the side of this… a burial-place has been constructed. What it was like originally it is difficult to say, beyond that a layer of thin … slabs of limestone occurred over the skeletons. This had probably been kept in place or supported by some structure of wood, as several large iron nails, some bent at right angles, were among the bones.’ If this were all that could be said about the burials, they would hardly merit a place in these pages. The chief interest of the record would be its apparent identification of the exact course of the Roman road at a point where this had hitherto been uncertain. Three objects associated with the second skeleton are, however, of exceptional interest.

Periodical Change

In a paper published in the ‘Proceedings of the Imperial Academy of Sciences of Vienna,’ vol. lxiv., Dr. Karl Hornstein has exhibited the results of a series of observations which appeared to show that the earths magnetism undergoes a periodical change in successive periods of 26 1/3 days, which might with great plausibility be referred to the rotation of the sun. It appeared to me that the deductions from the magnetic observations made at the Royal Observatory of Greenwich, and which are printed annually in the Greenwich Observations,’ or in the detached copies of ‘Results of Magnetical and Meteorological Observations made at the Royal Observatory of Greenwich, would afford good materials for testing the accuracy of this law, as applicable to a series of years. The mew results of the measured hourly ordinates of the terrestrial magnetic elements are given for every day, and it is certain that there has been no change of adjustments of the declination and horizontal-force instruments in the course of each year. For the horizontal-force instrument the temperature of the room has been maintained in a generally equable state, and in later years it has been remarkably uniform.

Little has been done towards solving the problem of the Saxon settlement of England by studying the types of villages and their distribution. Professor Maitland saw the importance of the subject and pointed out how valuable in this respect was the ordnance map ‘that marvellous palimpsest which under Dr Meitzen's guidance we are beginning to decipher’. Helpful, however, as the ordnance maps are, they cannot be read alone, a knowledge of the archaeology, history and topography of the district under review is a necessary equipment for such an investigation. The remarks here made are tentative and are offered in the hope they may be an incentive to others with local knowledge to examine the evidence of their districts.Professor Maitland, following Dr. Meitzen and others, has adopted two main types of settlements, namely, the scattered or dispersed, and the nucleated or clustered. These two types probably comprehend all forms of settlements, but certainly the nucleated type and possibly the scattered type, show many variants which it may be well to indicate before a methodical study of the subject can be made. I have elsewhere suggested the following classification of English towns and villages which will no doubt require modification and amplification but may meet a want for a preliminary inquiry; (I) scattered or dispersed settlements, (2) nucleated or clustered settlements off lines of communication, (3) nucleated settlements on lines of communication, (4) ring-fence settlements, (5) towns with bridge heads and double towns, (6) towns of gridiron plan, (7) towns of spider's web plan, (8) Bastide towns. Except for the first of these classes all of them are nucleated or clustered, and to this wider division I propose to devote my attention. It may perhaps be pointed out, however, that the scattered or dispersed settlements occur chiefly in Wales and in the west and north of England. They are found throughout Cornwall, in Devon, Somerset and the open parts of the Welsh border counties, in Yorkshire and Derbyshire, and probably they are the origin of the great parishes with their numerous townships of the other northern counties. They were adapted for a pastoral people and are generally to be found in moorland or mountainous country which has become divided into large parishes. They consist of hamlets and single houses or small groups of houses scattered somewhat promiscuously throughout a district. The principal hamlet from which the settlement or parish takes its name-which was probably the meeting place of the district and where the church was eventually placed-was generally on high land or a main road and frequently at cross roads, bridges, or such like places of nodality.

Early in 1967, a few months before the restored Meridian Building of the Old Royal Observatory was opened to the public by Sir Richard Woolley, the Astronomer Royal, I received a visitor in my office then in the Meridian Building — later, I was to move to the west summer house of Flamsteed House. My visitor was Colonel Humphrey Quill, Royal Marines, Master of the Worshipful Company of Clockmakers that same year and author of the hookJohn Harrison, the Man who Found Longitude, which has become a standard work. He brought with him some manuscripts written by the subject of this lecture — Nevil Maskelyne, fifth Astronomer Royal, who lived in Flamsteed House for 46 years from 1765, making most of his important astronomical observations in the very building in which Col. Quill and I were sitting.
