ceptionally large that it certainly ought to have been collected, 
weighed and examined, at least the nitrogen determined. The ani¬ 
mals’ systems were certainly flooded by the large amount of water 
drank, 196 pounds in five days, which is a little more than three 
times as much as the same sheep drank when fed on alfalfa hay and 
over four times as much as when fed on timothy hay. The heat re¬ 
quired to raise this quantity of water from the temperature at which 
it was drank, 14.5° C., to the the body temperature, taken 
as 101° F., would be 2,014,387 calories. So large a factor as this 
must have considerable influence upon the effects produced by the 
fodder, aside from the lively diffusion induced by the presence of 
an unusual quantity of water in the system.
