ON ANTHROPOLOGICAL TEACHING. 341 
Anthropological Teaching.—Report of the Committee, consisting of 
Professor H. B. TyLor (Chairman), Mr. J. L. Myres (Secretary), 
Professor A. MacauisTErR, Dr. A. C. Happon, Mr. C. H. Reap, 
Mr. H. Batrour, Mr. F. W. Rupier, Dr. R. Munro, Professor 
Furspers Perriz, Mr. H. Linc Rots, and Professor D. J. 
CUNNINGHAM, appointed to inquire into the present stute of Anthro- 
pological Teaching in the United Kingdom and elsewhere. 
Tue Committee desire to acknowledge with thanks the replies to their 
inquiries, which have been received from some seventy universities and 
colleges. 
A preliminary survey of the data thus collected is made at the 
Cambridge Meeting informally ; but the reduction of the material in 
the hands of the Committee to uniform and intelligible shape is a work 
of some difficulty, and makes it necessary to postpone the publication of 
the full report until next year. 
The State of Solution of Proteids.—Second Report of the Committee, 
consisting of Professor Hauuipurton (Chairman), Professor 
Waymouta Rew (Secretary), and Professor EK. A. SCHAFER, 
appointed to investigate the State of Solution of Proteids. 
In the last report evidence was given for the cases of ovalbumin, 
serum albumin, and globulin that the so-called solutions of these 
substances are really hydrosols, i.e., extremely fine suspensions in water, 
the evidence being that carefully prepared fluids containing these sub- 
stances exert no osmotic pressure upon a membrane impermeable to the 
proteid when water is exhibited on the opposite side. 
It was also mentioned that by collecting the washings during prepara- 
tion of the proteids mentioned, removing the salts, and boiling down in 
vacuo at 25°-30° C., a fluid quite free of proteid could be obtained, which 
gave a lasting osmotic pressure on a formalised gelatine membrane. 
The experiments of the past session have been devoted to finding a 
non-proteid substance to which gelatine is impermeable, though in true 
solution, which might account for the osmotic pressure of serum against 
its filtrate through gelatine, a pressure ascribed by Starling and Moore to 
serum proteids which my past experiments indicate are not in solution at 
all, and therefore not liable for the pressure noted by these observers. 
The material gained by washing serum proteids has been too small in 
amount to permit of satisfactory analyses, so that a series of substances 
likely to occur in sera (fresh or stale) have been employed for osmometric 
observation. 
The following substances all gave negative results : Calcic phosphate, 
calcic sulphate, sodic phosphates, sodic chloride, sodic carbonate, serum 
ash, soap, peptone, urea, glucose, indol, tyrosine, leucine, tryptophane, 
choline, glycerophosphates of sodium and calcium, acid hydrolysis 
products of proteid (fibrin), dialysed extractum caves! All these sub- 
stances went through the membrane and so gave no lasting pressure.
