physical character of the ancient Egyptians of the 
second and third dynasties. A paper by Prof. G. A. 
Reisner will describe his excavations at the pyramids 
of Giza, and Prof. W. M. Flinders Petrie will give

and the Rey. O. Blundell his investigations of ‘arti- 
ficial islands in Scottish lochs. The ethnographical 
papers include Dr. W. H. R. Rivers’s communica- 
tions on conyentionalism in primitive art and on navi- 
gation among primitive peoples, and Dr. C. S. 
Myers’s description of Sarawak music. 
Section | (PHys1oLoGy).—This year will be distin- 
guished by the number of well-known foreigners 
attending the section, more than twenty having 
accepted the invitation to be present. Apart from the 
address of the president of the section, Dr. Leonard 
Hill, F.R.S., and the reports of the various com- 
mittees, the provisional progamme is given below. 
One day (Friday) is to be devoted to psychology. A 
discussion on the relation of mind to body, in which 
Prof. Latta, Sir T. S. Clouston, Dr. J. S. Haldane, 
and Dr. H. J. Watt will take part, will be one of the 
features of this day. The following papers will also 
be read : Dr. J. L. McIntyre, r6le of memory in animal 
behaviour; Mr. C. W. Valentine, on a suggested 
physiological theory of the horizontal vertical illusion ; 
Mr. S. Dawson, on binocular and uniocular brightness 
discrimination. A discussion on the physiology of 
aquatic organisms with Section D (Monday) will be 
opened by Prof. B. Moore; Prof. A. Pitter will also 
take part. On Tuesday a discussion will be held on 
animal nutrition (see agriculture). Prof. Heger, of 
Brussels, has promised a kinematograph demonstra- 
tion, and the following papers will be read :—Prof. 
Leon Asher, on permeability of cells and a new 
method of vital staining; Prof. Max V. Frey, striated 
muscle under the action of veratria; Dr. E. Gley, le 
métabolisme du calcium chez l’animaux éthyroidés; 
Prof. Francis Gotch, colour perimetry in the dark- 
adapted eye; Prof. A. Kossel, die guanidingruppe im 
proteinmolkiil; Prof. J. J. R. Macleod, the relation- 
ship of the adrenal gland to the sugar content of the 
blood; Prof. C. R. Marshall, (1) the physiological 
action of quaternary methyl, ethyl, and methyl-ethyl 
ammonium compounds, (2) on coriamyortin and tutin, 
(3) the pharmacological action of nitric esters; Dr. 
R. R. Rentoul, the prevention of mental degeneracy ; 
Dr. A. P. Waller, (1) Herbert Mayo and the facial 
nerves, (2) the electrocardiagram by the oscillograph. 
Section K (Borany).—Ihe main purpose of the 
address of the president, Prof. F. Keeble, will be to 
show that the Mendelian method used by students 
of genetics in investigating the inheritance of plant 
and animal characters is an invaluable adjunct to the 
physiologist. In illustration of the need of this co- 
operation between genetics and physiology an account 
will be given of the result of recent research in the 
origin of plant pigments. In the course of this 
account the work done on the subject by Prof. Keeble 
in collaboration with Dr. Armstrong, will be described. 
A morning sitting will also be devoted to a joint 
meeting with Section B (Chemistry), during which 
kindred subjects will be discussed. The basis of the 
discussion will be the recent work of Dr. Eyre on 
enzymes, a summary of which will be given by Mr. 
Compton. The discussion will be followed by papers 
on genetics and related subjects. A_ joint meeting 
has also been arranged with Section D (Zoology), at 
which the question of the origin of life will be intro- 
duced by Prof. E. A. Minchin, F.R.S. On Monday 
afternoon a semi-popular lecture will be given by Mr. 
Burkill on the botany of the Abor expedition. The 
lecturer will present the results of a study of the hills 
of eastern Himalaya, and his account will be illus- 
trated by numerous lantern slides taken during the 
expedition. Papers have also been submitted dealing 
with various points related to the bacteria gymno- 
sperms, ecology, physiology, and palzeontology.
