maximum of 10°43, and minimum of 6°74 grains per minute. The 
tity increased after a meal and decreased from each meal, so 
minima were nearly the same, and the maxima were the greatest 
breakfast and tea. 
The effect of a fast of forty hours, with only a breakfast meal, waste 
uce the amount of carbonic acid to 75 per cent. of that which 
found with food; to render the quantity nearly uniform throughout!

and caused a dimunition in the carbonic acid as the temperature rose, 
' The effect of season was to cause a diminution of all the respiratory 
phenomena as the hot season advanced. The maximum state was 
spring, and the minimum at the end of summer, with periods of decrease 
in June and of increase in October. The diminution in the author : 
30 per cent. in the quantity of air, 32 per cent. in the rate of ets 
and 17 per cent. in the carbonic ‘scid. The influence of temperature WS ; 
considered in relation to season, and it was shown that vines sudden 
changes of temperature cause immedi te variation in the quantity of 
bonie acid, a medium degree of temperature, as of 60°, is scons
