Mr. Moul 8 per minute. The quantity of air was reduced in myself 52 cubic inches per 
minute. 
Brandy . 20 (6 exps.). fi oz. of excellent brandy, with water, caused in me 
an average decrease of '2 gr. of carbonic acid, and a maximum of '38 gr. per minute. 
April 24 (6 exps., Plate XXXVI. fig. 62). — 2 oz. gave me an average decrease of -38 gr., 
and a maximum of -71 gr. per minute, and to Mr. Moul '02 gr. and -62 gr. respectively,- 
but in him there was, on two occasions, an increase of -4 gr. per minute. The quan- 
tity of air fell 42 cubic inches and 37 cubic inches per minute in myself, and 34 cubic 
mches per minute in IVIr. Moul. My rate of respiration and pulsation fell on both 
occasions, whilst in Mr. Moul the former varied and the latter fell a little. 
t7m.— April 27 (6 exps.), Plate XXXVI. fig. 48. 2 oz. of fine old British gin, with 
6 oz. of cold water, gave me a maximum decrease of I '52 gr. of carbonic acid in half an 
hour, and an average decrease of -65 gr. per minute in 86 minutes. In Mr. Moul the 
average decrease was -2 gr., and the maximum -4 gr. per minute. The volume of air 
was reduced 56 cubic inches in myself, but it was unchanged in Mr. Moul. The rate 
of respu-ation fell m myself, but it varied much in Mr. Moul ; whilst that of pulsation 
fell 6 per minute in myself, and was unchanged in Mr. Moul. 
Dec. 21 (4 exps.).— The same quantity of newer and probably inferior gin, taken in 
die afternoon, gave me a maximum decrease of -46 gr. of carbonic acid and 43 cubic 
mches of air per minute, the diminution ending in three-quarters of an hour. The rate 
of respu-ation slightly fell, whilst that of pulsation rose 5 per minute. There was a 
decrease in the amount of vapour exhaled from the lungs, from 3-12 grs. to 2 '7 grs. per 
minute (-699 gr. and -667 gr. to 100 cubic inches). 
April 8 (6 exps.). fi oz. of Navy rum, spec. grav. -900 (58 per cent.), with 
water, taken in the afternoon, gave me a maximum increase in carbonic acid of '78 gr., 
andean average increase of -26 gr. per minute, whilst Mr. Moul had a maximum increase 
of -7 gr. per minute. The volume of air was increased 13 cubic inches and decreased 
49 cubic inches in myself, and in Mr. Moul it was decreased 80 cubic inches per minute. 
The rate of respiration fell, and chiefiy in Mr. Moul ; whilst that of pulsation rose in 
myself and fell in IVIr. Moul. On another occasion, April 10 (7 exps., Plate XXXVI. 
fig. 49), in the morning, the increase of carbonic acid was much greater, viz. a maxi- 
mum of 1-24 gr. in myself, and 2-14 grs. per minute in Mr. Moul. The quantity of air 
inspired varied in myself, but in Mr. Moul it was increased 82 cubic inches per minute. 
My rate of respiration fell, and that of Mr. Moul fell greatly, and his rate of pulsation 
fell also. The depth of inspiration was increased in both of us. 
April 30 (7 exps.).— 2 oz. of very fine old rum, spec. grav. -875 (69 per cent.), taken 
in the morning, gave to me a maximum increase in carbonic acid of only -1 gr., but to 
Mr. Moul of 1-5 gr. per minute. There was a maximum increase in the quantity of air 
of 11 cubic inches m myself, and 40 cubic inches in Mr. Moul per minute. The rate 
of resphation fell towards the end of the inquiry in myself, and at an earlier period in 
Mr. Moul. His pulsation also fell a little, whilst mine rose.
