The various factors which are supposed to influence the composition of milk have already been the subject of numerous investigations. The general result of these has been to show that within very wide limits the composition of milk is very little affected by the nature of the food supplied. As regards the mineral constituents the results of some of the investigations are rather conflicting, and while there is a general consensus of opinion that the composition and amount of the mineral constituents are independent of the food-supply, certain investigators claim to have been able to increase both the calcium and phosphoric acid in the milk by slight amounts.

Q. 19 (Sūrat Maryam) – an end-rhyming, and, by general consensus, middle to late Meccan sura of 98 (or 99) verses – has been the subject of considerable exegetical and scholarly attention. Besides commentary, naturally, in every tafsīr of the Qur'an, Sura 19 has also benefited from separate, individual treatment. It has been the object of special attention by modern Western scholars, in particular those of comparative religion and of Christianity, whose attention has centred largely on the virtue and piety of Mary, on the miraculous nature of the birth of Jesus, on Jesus' ministry, and on how Jesus' time on Earth came to an end. In addition, Sura 19 is a favourite of the interfaith community. Given this sustained and multivectored scrutiny, it is remarkable how little analysis has been devoted to its lexicon. This article is a contribution to the study of the lexicon of this sura, with a particular emphasis on three features: rhyming end words, hapaxes, and repeating words and roots, some of which occur in this sura alone.

As the rare descent of Meteorites or Aërolites affords us the only real tangible evidence we possess respecting the mineral constituents which exist beyond the limits of our own globe, a great degree of interest must always be attached to these stray visitors ; and although much has been written on the subject at different times, it has hitherto taken the form either of a bare catalogue of the date and place of occurrence ; or of scattered notices dealing only with individual cases. My desire is to collect these various records as far as they relate to each meteoric stone which has been known, or has been said to have fallen in Great Britain, and to endeavour to give as complete an account as possible of every instance; including not only the historical facts, but also notices Of mineralogical observations and references to authorities.

1. 670 samples of the mixed milk from 15 herds were analysed, and the average percentages of total ash, soluble ash, insoluble ash, lime and phosphoric acid are given.2. Tables showing frequency distributions are also given, with the standard deviation, mean and probable error of mean for each constituent determined.3. Various correlations of these constituents with solids not fat and protein have been prepared, and these correlations are illustrated by graphs.It is observed that the total ash falls with the solids not fat until low values of solids not fat are reached, when the ash content appears to rise. This variation is confirmed by a curve illustrating the variation in ash content of samples of individual cow’s milk. Soluble ash rises as the solids not fat falls, but the insoluble ash shows a reverse variation. Lime and phosphoric acid both fall with the solids not fat.

In a series of papers inserted in the Philosophical Transactions (1835,1836,1837), and afterwards, in a more correct and complete form, in my Treatise ‘On the Undulatory Theory applied to the Di­spersion of Light’ (1841), I endeavoured to investigate the great problem of the explanation of the unequal refrangibility of light on the principles of the undulatory theory, as proposed by M. Cauchy about 1830, by numerical comparison with the indices observed, more especially in cases of the most highly dispersive media then examined. The general result then arrived at was, that while the theory applied perfectly through an extensive range of media of low and moderate dispersive power, it did not apply well to those of higher; and to the highest in the scale (which of course formed the true test of the theory) it did not apply within any allowable limits of accuracy. Since that time little has been done towards prosecuting the subject.


In the last year or two there has been a remarkable increase in the interest, both popular and scientific, in the subject of climatic change. This stems from a recognition that even a highly technological society is vulnerable to the effects of climatic fluctuations and indeed may become more so, as margins of surplus food production are reduced, and nations become more interdependent for their food supply. In this respect our concern is with quite small changes - a degree (Celsius) or less in temperature and 10 % or so in rainfall. Probably we may discount some of the more alarmist suggestions of an imminent and rapid change towards near glacial conditions as these are based on very sketchy evidence. However, whatever the time-scale of climatic fluctuations with which we are concerned, we may hope to learn a great deal which is relevant to the factors which will control our future climate from the study of its more extreme vagaries in the past. Information relevant to the weather in such extreme periods is coming forward in increasing detail and volume from a wide range of disciplines. The variety of the evidence, its lack of precision as a strict measure of climate, and the number of different sources all make it difficult for an individual to build up a clear picture of past climates. However such a picture is needed, if explanations and interpretation are to be possible. Ideally one would need a synchronous picture of the climate of the whole world at selected epochs in the past. Various international programmes are directed to forming such pictures.

The Satyrica has long been associated with a Neronian courtier named Petronius, mentioned by Tacitus in his Annals. As such, the text is usually dated to the mid first century c.e. This view is so established that certain scholars have suggested it is ‘little short of perverse not to accept the general consensus and read the Satyrica as a Neronian text of the mid-60s ad’. In recent years, however, there has been a groundswell of support for re-evaluating this long-held position. Laird, after comparing the ‘form and content’ of the text to the Greek novel, came to the ‘unattractive’ conclusion that the text may be second century. Similarly, in two recent pieces in CQ, Roth argues that the manumission scene in the Cena establishes a new terminus post quem for the text; she suggests that the freedoms granted by Trimalchio closely parallel—and parody—descriptions of awarding ciuitas found in the letters of Pliny the Younger. Indeed, the three slaves manumitted in the novel are associated with a boar (Sat. 40.3–41.4), Dionysus (Sat. 41.6–7) and a falling star (Sat. 54.1–5); likewise, the three slaves that are the subject of Pliny's letter are C. Valerius Aper (boar), C. Valerius Dionysius (god of wine) and C. Valerius Astraeus (stars). Roth's argument suggests that the author of the Satyrica was not Nero's contemporary but a member of Pliny's intellectual circle, offering strong circumstantial evidence that troubles the accepted tradition on the work's authorship and date.

Until recently, the subject of Calderón's dominance of eighteenth-century popular theatre has been a closed case. What discussion there had been was centered on the heated polemics which surged during the second half of the century between the rabidly anti-Calderonian neo-classicists and the pro-Calderonian nationalists. Despite their conflicts over the literary and dramatic quality of his work, the general consensus on both sides was that Calderón's plays enjoyed widespread popularity among theatre-goers, and that his style influenced successive generations of dramatists throughout the century.


It has long been the accepted theory that plants obtain the mineral constituents they require from the soil through the intermediary of a solution that is formed in the water with which the soil particles remain in contact. As, however, the amounts of phosphoric acid and potash revealed by analysis are always far in excess of the requirements of the crop, and as the variation in these quantities in no way determines the need or otherwise for a further supply of the constituents in the shape of fertilisers, Daubeny suggested a distinction between dormant and available plant food in the soil, the latter being the more readily soluble compounds of phosphoric acid and potash, which in virtue of their solubility determine the amount of each constituent obtainable during the short season of a plant’s growth. This point of view was revived by B. Dyer in 1894, and has been subjected to considerable examination, without, however, revealing any constant correspondence between the quantities of easily soluble plant food and the response of the soil to particular fertilisers. A new aspect of the problem was set forth in 1903 by M. Whitney and F. K. Cameron, who maintained that as all soils contain practically the same compounds of phosphoric acid and potash possessing a very low solubility, the soil solution must become saturated with these constituents to the same low degree of concentration in all soils, irrespective of the actual amounts of phosphoric acid and potash there present.

The hierarchy of food supply in besieged Leningrad is one of the most polemical questions in historiography. The subject of this research is the measures taken by the city administration during the first winter of blockade (1941-1942) aimed at maintenance of vitality of Leningraders who were highly valued for economy of the city or regarded as creative elite of the city. The goal consists in clarification of facts on the work of medical and nutritional inpatient facilities intended for persons suffering from dystrophy, including municipal inpatient facility for emaciated workers of science, technology, art and executive personnel, located the Hotel Astoria. The work of medical and nutritional inpatient facilities in the period from January to April of 1942 had not previously become the subject of separate research for national or foreign historians. The conducted research demonstrate that the establishment of such healthcare facilities was the first attempt to organize food supply for citizens suffering from dystrophy. In the conditions of severe shortage of food resources, the city administration was able to help only a limited circle of people. Working in the extreme conditions with no electricity, water, shortage of qualified medical personnel, limited food funds, medical and nutritional inpatient facilities were could not fully solve the tasks imposed on them.
