 R. Dean have been elected to fellowships at Trinity 

 College. 



A letter from the Chairman of the University of 

 CambridKC C-ommissioners has been received inviting 

 repri'sentations from University bodies and from 

 individual memlwrs or groups of meml>ers of the 

 Senate on matters m which they desire the proposals 

 of the recent Koyal Commission to be modified. 

 These should be sent before the end of the year to 

 the Secretary' to the Commissioners, Mr. H. A. MoUond, 

 Trmity College. 



Edinburgh. — Prof. J. J. R. MacLeod, professor of 

 physiology m the University of Toronto, who was 

 awarded the Cameron prize for 1923, delivered two 

 lectures in the U'niversity on October 16 and 17 

 r^pectively, on the nature of control of the meta- 

 bolism of carbohydrates in the animal body. He 

 dealt with the discovery of insulin and its value in 

 the investigation, not only of diabetes, but also of 

 other problems of metabolism. The Cameron prize 

 was founded in 1878, and is awarded to an investigator 

 who in the course of the five years immediately 

 preceding has made an important addition to practical 

 therapeutics. 



Prof. T. J. Mackie, formerly professor of bacterio- 

 logy' in the University of Cape Town, who was 

 recently appointed Robert Irvine professor of 

 bacteriology, devoted his inaugural address to a 

 survey of the present position of medical bacteriology'. 

 Prof. Mackie has made arrangements for developing 

 the teaching of bacteriology as a subject for the 

 degree of B.Sc. 



Dr. J. E. M'Cartney has resumed duty as lecturer 

 in bacteriology after a year's leave of absence granted 

 to enable him to carry out researches on certain 

 filterable viruses in the Rockefeller Institute. 



Leeds. — ^The West Riding County Council has 

 decided to devote the proceeds of a penny rate to 

 the a.ssistance of university education, which has 

 already in the past been consistently supported by 

 the Council. 



Mr. W. F. Shanks has been appointed professor of 

 physiology. Dr. Shanks graduated B.Sc. at the 

 University of Glasgow in 191 3, with special distinc- 

 tion in physiology, and M.B., Ch.B., in 1915 with 

 commendation. In 1920 he was appointed lecturer 

 in physiology at Glasgow and acted as senior assistant 

 to the Regius professor of physiology. For the last 

 tliree years he has also been in sole charge of a 

 special course in physiology for the new degree of 

 Bachelor of Education (Glasgow), in which the 

 subject is treated from a special point of view with 

 regard to the physiology of the child, psychology, 

 and other cognate aspects. 



The following further appointments have been 

 made : Mr. F. J. Brown to be assistant lecturer in 

 zoology; Mr. A. W. Anderson and Mr. J. McGregor, 

 district lecturers in agriculture ; Mr. G. Milne, 

 temporary assistant lecturer in agricultural chemistry ; 

 Mr. H. Preston, assistant science tutor ; Miss M. K. 

 Morgan, assistant lecturer in geography ; and Miss E. 

 Newcomb, assistant lecturer in education. 



London. — Free public lectures on " The Treatment 

 of Injuries of the Long Bones produced by Accident 

 or Disease " will be delivered by Prof. E. W. Hey 

 Groves at Guy's Hospital Medical School at 5.30 

 on November 8, 9, 12, and 13.

 in the chair. — A. Lacroix : The composition of rli^ 

 meteorite which fell at Saint-Sauveur ( 1 1 

 Garonne) in 191 4. The examination by mt. . 

 graphic methods proved the presence of metal 

 (nickeliferous iron) and enstatite, with smaller nro- 

 portions of clino-enstatite, oldhamite, maskc! 

 apatite, and graphite. A complete chemical an

 to the study of the changes in the surface tension 

 at the surface of separation of vaseline oil and aqueous 

 solutions. The latter included solutions of caustic 

 soda and sodium carbonate, of sodium carbonate and 

 sodium bicarbonate, and of caustic soda with common
