I have the honour to lay before the Royal Society a short account of some theoretical researches on the daily change of the temperature of the air, made by me in 1895, and published to a certain extent in the Nova Acta der kaiserlich Leopoldinisch-Carolinischen Academie der Naturforscher, Band lxvii., No. 2. Some more recent investigations on the subject, chiefly dealing with the physical point of view of the problem, have not yet been published, but seem to me of such importance as to justify me in presenting a brief sketch of them to the Society in this paper.The history of the mathematical aspect of the problem can be traced back as far as the middle of the last century, when Lambert made the first attempt at investigating the relation between solar and terrestrial radiation and the temperature of the atmosphere. He was succeeded by a great number of famous mathematicians and meteorologists, whose labours, however, though they contributed considerably to our knowledge of certain parts of the question, have not been rewarded, it must be said, with any sufficient result; so that a satisfactory solution of the problem by means of theoretical investigations has been eventually considered impossible, at least in some quarters.There can be no doubt that, in a problem like this, an immense number of different errors affect the principal conditions of the propagation of heat, which conditions are supposed to be the causes of the observed changes of the temperature.

When I had the honour of being asked by the Council of the Royal Society to give the following address, I chose the subject partly because it had been brought under the notice of the fellows by my predecessor, Professor Kelland. His memoir was written comparatively early in the history of the subject; and he seems to have been but little acquainted with what others had done even up to the time at which he wrote. Accordingly, although the subject is treated very ably in his paper, it is treated from only one point of view; and, indeed, one side of it is left out of sight altogether. The relation of the whole theory to the question of the origin and mutual independence of the axioms of geometry has been made much clearer of late, and I believed that some account of the more modern views might be of interest.

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.

In a paper treating mainly on the structure of the Heliopora cœrulea , which was communicated to the Royal Society in the autumn of last year (1875), I gave a short account of the results at which I had arrived from the examination of two species of Millepora obtained at Bermuda and at the Philippines, and expressed my intention of further prosecuting the subject at the Sandwich Islands and Tahiti, should material be forthcoming. At Honolulu no Millepora was met with; and this form apparently does not occur at the Sandwich Islands, the water being too cold for it. At Tahiti a Millepora is very abundant on the reefs in from one to two feet of water, and is very conspicuous because of its bright yellow colour.

Molecular Constitution

About twelve months ago I had the honour of presenting to the Royal Society an account of a series of researches into the molecular constitution of the volatile organic bases: at present I beg to submit to the consideration of the Society the history of a new group of alkaloids, which, although intimately connected with the former by their origin, differ from them altogether by their properties, and especially in not being volatile . The members of this new group of alkaloids are so numerous, their deportment is so singular, and their derivatives ramify in so many directions, that I have not as yet been able to complete the study of these substances in all their bearings; nor is it my intention to go fully into the chemistry of the subject in the present com­munication, my object being merely to establish the existence of these bodies, and to give a general outline of their connection with the volatile bases, and of their most prominent chemical and physical properties, reserving a detailed description of their salts and derivatives to a future memoir.

The Subject

Following the political upheavals of 1978, the history and development of Shiite religious thought in modern-day Persia has been the subject of detailed scholarly studies, but the modern development of Sufism—the mystical tradition that lies at the heart of traditional Persian culture, literature and philosophy, which is, from the cultural and literary point of view at least, the most fascinating aspect of the Perso-Islamic religious tradition—remains almost completely uncharted. In contrast to the classical and medieval periods of Persian Sufism which have undergone much scholarly investigation in recent years, the study of the modern period of Iranian tasawwuf, though far better known and documented, has been seriously neglected by scholars.

Макалабызда кыргыз тили менен түрк тили негизге алынды. Категория залога - есть необходимая категория языковой мысли, присущая общению. Важнейшей особенностью категорий залога является отношение между субъектом и объектом действия. В предложении данная категория определяет, является ли реальный исполнитель слова или действия, выполняющий функцию, субъектом или объектом, и означает ли что действие было разработано кем-то другим. В этой статье мы проанализируем категорию залога с исторической и семантической точек зрения в кыргызском языке. Определяя значения, мы будем анализировать историю этих залогов от древнего Коктюрского времени до наших дней и подробно обсуждать лингвистические методы, с помощью которых они сформированы. Наша статья основана на материале кыргызского и турецкого языков. The collateral category is a necessary category of linguistic thought inherent in communication. The most important feature of the categories of collateral is the relationship between the subject and the object of the action. In a sentence, this category determines whether the real performer of a word or action performing a function is a subject or an object, and means that the action was designed by someone else. In this article, we will analyze the category of collateral from a historical and semantic point of view in the Kyrgyz language. By defining the meanings, we will analyze the history of these pledges from ancient Cocturian times to the present day and discuss in detail the linguistic methods by which they were formed. Our article is based on the material of the Kyrgyz and Turkish languages.

In general terms, this paper is about the possibilities newly available to art historians, because of the new cheapness, of computing, and the problems which still exist in the areas of data and image storage, retrieval and display. First it tries to assess the technology from a layman’s point of view, then ventures into the contentious matter of how many art historians (in these days of reduced funding) are either able or willing to take advantage (if there are advantages) of new technology. Threading throughout the paper are doubts about whether the use of computers can or will advance the study of the subject (as opposed to making that study easier), and about whether the finance for some of the hardware mentioned could ever be raised by any non-scientific department.

Source Materials

John Lingard (1771–1851) was the first English historian to attempt to look at the history of England in the sixteenth century from an international point of view. He was unconvinced by the story of the Reformation in England as found in the works of previous historians such as Burnet and Hume, and believed that new light needed to be thrown on the subject. One way of doing this was to look at English history from the outside, so to speak, and Lingard held it to be a duty of the historian ‘to contrast foreign with native authorities, to hold the balance between them with an equal hand, and, forgetting that he is an Englishman, to judge impartially as a citizen of the world’. In pursuit of this ideal Lingard can be said to have given a new dimension to the source materials for English history. As parish priest in the small village of Hornby, near Lancaster, Lingard had few opportunities for travel. But he made good use of his various friends and former pupils at Douai and Ushaw colleges who were settled now in various parts of Europe. It was with the help of these friends that Lingard made contacts with and gained valuable information from archives in France, Italy and Spain. We shall concern ourselves here only with the story of Lingard's contacts with the great Spanish State Archives at Simancas.

As the identity of the large mass of meteoric iron in the British Museum with the celebrated Otumpa iron, described by Rubin de Celis in the Philosophical Transactions for 1786, has been the subject of frequent inquiry, the following short historical notice, relating to that mass, is communicated by Woodbine Parish, Esq. F. R. S., by whom, when His Majesty’s Chargé d’Affaires at Buenos Ayres, it was sent to England. -C. K. “Dear Sir, “Agreeably to my promise, I have taken some trouble to ascertain the precise history of the large mass of native iron which I sent home to Sir Humphry Davy from Buenos Ayres, and which is deposited in the British Museum. There is no doubt of its coming from the same place as that described by Rubin de Celis, though whether it be a fragment of that particular mass upon which he made his report, or a smaller one in its immediate vicinity, I am not able to say, for there certainly is an impression at Buenos Ayres that there is not only one, but that several masses of this iron are to be found in that part of the Gran Chaco referred to by Rubin de Celis. I was under the impression that it had been sent for in order to be forwarded to Madrid; but in this I was led into error; and I have only lately ascertained through Mr. Moreno, the Buenos Ayrean Minister, that the real history of its being at Buenos Ayres is as follows.

Organic Decomposition

The chemical examination of ground-air, i.e., the air which is contained in the pores of the soil, was first made by Boussingault and Levy in 1853. Their results, however, attracted little attention till Pettenkofer, in 1857, pointed out that the determination of the amount of carbonic acid in the air of a given soil might be used as a means of estimating the organic decomposition going on there. In 1871 he first published his results, and since that time the subject has been worked at by many investigators both from the agricultural and hygienic point of view, including in the latter class Fleck at Dresden, Eodor at Buda-Pesth, Hesse in Saxony, and Nicholls in America. As researches of this nature have not attracted much attention in this country, a short account of the modus operandi may be interesting as a preliminary.
