AJVD OTHEE PHENOMENA OE EESPIEATION. 
hence, without removing from my place, there was a small degree of exertion made In 
the two former inquiries exertion was taken in the intervals of the examinations but 
we sat down some minutes before each experiment was renewed. It is probable that in 
Dr. Moeie’s case there was on a few occasions a little excess in the results, owing to the 
want of close attention to the latter circumstance. On a review of these experiments, 
I believe that the two former, viz. those in which the experiment was not continuous’ 
may be taken to represent the state of the system at rest, and the two latter in ordinary 
but not absolute quietude, that is, in the state in which men remain when slightlv 
engaged but not moving the whole body. ' 
The periods above mentioned include nearly 18 hours, viz. from 6 a.m. to 11 p.m., or 
fiom 7 A.M. to 12 P.M. all inclusive,- and in order to compare them, I have made shh 
addition by computation to each as will include that period; and I regard the results as 
indicating the true state of the system during the working day. The particulars of the 
computation are as follows : — 
Computation of the Carbonic Acid expired in eighteen hours from the returns 
obtained in the four inquiries. 
March 12, The inquiry embraced the whole period. 
May 15. The inquiry was continued through 16^ hours.

Food was taken at 83 a.m., 1|, 5 ^ and 8|^ p.m., in all the experiments. The break- 
as consisted of good tea with sugar and milk, bread, butter, bacon or eggs. The
