AjSTD othee phenomena OE EESPIEATION. 695 
Hence the average of the whole was 8-8 grs. per minute, and the proportion was, 
in myself, Mr. Moul, Dr. Mueie and Professor Feankland in order, 1 gr. of carbonic 
acid to 58 cubic inches, 54-8 cubic inches, 58-5 cubic inches, and 54-7 cubic inches of 
mspired air, whilst on the whole it was 1 gr. to 56-3 cubic inches. This is a loiver pro- 
portion than occurs in fasting (the normal state of the system), and much lower than 
with exertion, in which it increases as the exertion increases. Thus in walking at two 
miles per houi- it was 1 to 44 T cubic inches, and at three miles per hour 1 to 39*7 cubic 
inches. 
In the above experiments the average temperature with the dry-bulb thermometer was 
o8°-18, 63°-4, 60°-6, and 72°-2, yielding a total average of 63°-6. The barometric pressure 
was on the average 29-72, 29-04, 30-13, and 29-63, or a total average of 29-63 inches. 
C. Rate of Respiration. 
This was as foUows on the average per minute in each of the three first series of experi- 
ments. It was not recorded in the last one.

The total average in myself was 14-54, and in Mr, Moni, 13-5 ; whilst that of the whole 
series was 13-87 per minute. 
D. Depth of Inspiration. 
The average depth of inspiration was in myself, 39-5 cubic inches; Mr. Moul, 33-8 
cubic inches ; Dr. Mueie, 30 cubic inches ; and Professor Feawkland, 30-9 cubic inches ; 
giiing a total average of 33-6 cubic inches. 
E. Rate of Pulsation.

The factor of the respirations required to render the numbers of respirations and 
pulsations equal, was in Mr. Moul, 5-72; myself, 5-25; Professor Feanklaxd, 5 ; and 
r. Mueie, 4-63; variations which are very noticeable and follow the order of age. 
Ihe total average was 5-15.
