XVill. ABSTRACT OF PROCEEDINGS. 
given of Professor Atwater’s respiration chamber and the 
ergometer, by which definite values based on thermo- 
dynamic principles were obtained in cases of students, 
athletes and others who had volunteered to offer themselves 
as living experiments. The lecturer stated that he had 
found from his own observations and experiments, that a 
much smaller intake of food sufficed for mental work, much 
smaller than that given by Pettenkofer and Voit, and more 
nearly that found by Chittenden. 
Remarks were made by Messrs. J. H. Marpsn, J. U. C. 
COLYER, S. H. BARRACLOUGH, W. A. DIxON, and the Presi- 
dent. Mr. HAMLET replied. 
On the suggestion of Mr. MAIDEN, it was agreed that at 
some future meeting, to be arranged by the Council, a dis- 
cussion be held on the subject of ‘The nutrition of man.” 
Members desiring to take part in the ‘symposium’ were 
invited to send in their names to the Honorary Secretaries. 
At the request of the President, Mr. MAIpEN will begin 
the discussion. 
It is proposed to issue the Society’s Volume in Parts, 
unbound, to such members as desire the publication to be 
issued to them in that form. The precise number of parts 
to be issued each year has not yet been decided upon; they 
may be issued irregularly. A printed form of application 
is obtainable for the convenience of members. To those 
members who do not sign the form, the bound volume will 
be delivered at the end of each session as heretofore. 
EXHIBITS : 
Mr. HAMLET exhibited a Colorimeter by Dubosq of Paris, 
which he had found useful in estimating the intensity of 
colours in artificially coloured food stuffs. Another form 
of Colorimeter by Stammer, was exhibited, having a more 
extended scale, and adapted for measuring the colour in ~ 
fictitious raspberry syrups, fruit essences, etc.
