Page 176 - In the third of these contributions2 we saw that the repeated migrations of Greeks into the Fayum, beginning about 2,500 years ago, and ending soon after the start of the Christian Era, have left no trace of an effect to-day on the physique of the modern dwellers in this oasis. The latter have a nasal index which is distinctly higher than that which occurs among the northern provinces of the Delta, and almost identical with the index found in the Nile Valley in the same latitude as the Fayum. There...
Page 352 - They were obtained by the addition of methyl iodide to the corresponding bromanilines ; consequently in the latter also the bromine atom is in the para position. The decomposition and nitrification, of sewage (1) in alkaline solutions, (2) in distilled water. ' By JE PURVIS, MA, St John's College, and RM COURTAULD, MA, MB, Pembroke College. [Read 25 November 1907.] In a paper by Purvis and Coleman on "The influence of the saline constituents of sea-water on the decomposition of sewage...
Page 420 - ... increases [as intensity increases], the velocity with' which individual corpuscles come from the metal does not depend upon the intensity of the light. If this result stood alone, we might suppose that it indicated that the forces which expel the corpuscles from the metal are not the electron forces in the light wave incident on the metal, but that the corpuscles are ejected by the explosion of some of the molecules of the metal which have been put into an unstable state by the incidence of the...
Page 281 - We suppose that the mass of an atom is the sum of the masses of the corpuscles it contains, so that the atomic weight of an element is measured by the number of corpuscles in its atom.
Page 420 - ... has investigated the velocities of corpuscles emitted under the action of ultra-violet light of different wave-lengths, and finds that the velocity varies continuously with the frequency ; according to his interpretations of his experiments, the velocity is directly proportional to the frequency.2 Thus, though the velocity of the corpuscles is independent of the intensity of the light, it varies in apparently quite a continuous way with the quality of the light ; this would be very improbable...
Page 198 - G's hens is responsible for 3 nests, and 13 eggs, which produced 11 cocks and 2 hens. Thus to compare the two. In G's aviary a more regular temperature was kept during the breeding time ; there was more light and sun in the room ; less food was given ; hatching and moulting took place earlier as a rule ; only about half the percentage of loss was experienced ; and from the nests in which all eggs were hatched, the proportion of cocks produced was more than three times the proportion obtained in N's...

The spark-spectra of lead, tin, antimony, bismuth and gold, in a strong magnetic field. By JE PURVIS, MA, St John's College. 2. /3-rays from Potassium. By NR CAMPBELL, MA, Trinity College. . 3.

Page 178 - Our new anthropometric data favour the view which regards the Egyptians always as a homogeneous people, who have varied now towards Caucasian, now towards negroid characters (according to environment) , showing such close anthropometric affinity to Libyan, Arabian and like neighbouring peoples, showing such variability and possibly such power of absorption, that from the anthropometric standpoint no evidence is obtainable that the modern Egyptians have been appreciably affected by other than sporadic...
