OF FOODS UPON THE EESPIEATION.

On many occasions we took a cup of tea with a view to relieve the system after expe- 
nments with other substances ; and the results have much interest, as showing their 
uniform direction and the rapidity of the action of tea. We both took milk with it, 
but I alone took sugar. 
April 24.— After having taken brandy, tea gave to myself and Mr. Moul in fifteen 
minutes an increase of carbonic acid of -62 gr. and 2-68 grs., and of air 25 cubic inches 
and 108 cubic inches per minute. 
May 16. — After cocoa had increased the resphation in myself, but scarcely in 
Mr. Moul, tea gave us an increase in carbonic acid of -2 gr. and 2-2 grs., and in air of 
9 cubic inches and 78 cubic inches per minute. 
May 28.— Wter an experiment on rice, 50 grs. of tea infused one minute, gave 
Mr. Moul an mcrease in carbonic acid of 1 gr., and in air of 17 cubic inches per minute. 
May 29. — After having taken whisky, the same quantity of tea infused two minutes, 
gave us in ten minutes an increase in carbonic acid of ’96 gr. and l'32gr. of carbonic 
acid, and 50 cubic inches and 56 cubic inches of air per minute. 
May 30. — After an experiment on rum, tea caused a small decrease in my carbonic 
acid with a slight increase of air ; but Mr. Moul had in twenty-five minutes an increase 
of '92 gr. of carbonic acid and 48 cubic inches of air per minute. 
June 21. — After an experiment on arrowroot and butter, 1 had again a small decrease 
in the carbonic acid, whilst Mr. Moul had an increase of 2-12 grs. and 98 cubic inches 
of air per minute. Neither substance agreed with us. 
Coffee . — April 6 (4 exps.), April 9 (6 exps.), April 15 (6 exps.), Plate XXXVI. fig. 39, 
May 3 (7 exps.), fig. 40. 4 an oz. of good coffee gave to myself and Mr. Moul, on three 
occasions, the following increase per minute: — Carbonic acid, -98 gr. and 1-02 gr., 9 gr. 
and -4 gr., 1-16 gr. and 2-54 grs.; air, 36 cubic inches and 14 cubic inches, 40 cubic 
inches and 34 cubic inches, 35 cubic inches and 84 cubic, inches, f of an oz. gave us an 
increase per minute of carbonic acid, 1-08 gr. and -82 gr. ; and of air, 28 cubic inches and 
54 cubic inches per minute. The rate of respiration, but not of pulsation, was increased 
in myself, whilst in Mr. Moul the increased rate of both functions was much less than 
in myself in the first experiment ; and in the others there was no increase. The increase 
in the depth of inspiration was not great. 
April 27. — A cup of coffee with milk, after an experiment on gin, gave neither of us 
any increase of carbonic acid or air within a short period. 
May 6. — f of an oz. of coffee with milk gave us, after an experiment on wine, 
an increase in carbonic acid of •68gr. and l'68gr., and of air 64 cubic inches and 86 
cubic inches per minute in thirty minutes. 
Cfnconj . — May 17 (7 exps.), Plate XXXVI. fig. 42. 4 of chicory with 8 oz. 
of boiling water, gave to myself and Mr. Moul a maximum increase in carbonic acid of 
1T7 gr. and ‘66 gr. per minute, whilst the quantity of air inspired was increased 27 cubic 
inches and 42 cubic inches per minute. The rate of respiration and pulsation fell con- 
siderably in Mr. Moul, whilst in myself the latter was lessened 1 per minute and tlie
