stances, from one and one-half to two pounds of water in 
the state of insensible perspiration. The difference be¬ 
tween the weight and that of one-third of the whole food, 
solid and liquid, represents the quantity of water daily 
discharged from the lungs. It is not far from the truth 
to say that for every one and one-half pounds discharged 
from the skin, about one pound is given off from the 
lungs.” Those desirous of pursuing the subject further, 
can consult Ziemssen on Skin Diseases, page 67 ; Pepper, 
Practice of Medicine, Yol. 4, page 436 ; Tidy’s Legal Med¬ 
icine, Vol. 2, page 197 ; Storer’s Agriculture, Vol. 1, pages 
481-489; ArmSby’s Manual of Cattle Feeding, pages 198,

While we cannot compare the human subject with the 
domestic animals, it is reasonable to infer that the causes 
that influence one will influence the other. Selecting the 
average, it will be seen that the loss is about one-third 
of the water drank; that the amount of urine voided was 
practically the same, while the dung of No. 1 was 54 
pounds, 10 ounces, it contained 82.9 per cent, of moisture, 
or 17.1 per cent, of dry matter; while the dung of No. 2 
was 49 pounds, 5 ounces, it contained 81.7 per cent, of 
moisture, or 18.3 per cent, of dry matter. 
The dry dung of No 1 was 43.2 per cent, of the hay 
eaten, while the dry dung of No. 2 was 41.8 per cent, of 
the hay eaten. The increased gain of 15 pounds of No. 
2 over No. 1 was due, as shown by the above figures, to 
No. 2 being a better feeder, he having digested 1.4 per cent, 
more of the dry substance of the alfalfa and assimilated 
it. The refuse hay, which amounted to but a few ounces 
a day, was taken into account in the above calculation. 
The urine when analyzed was slightly alkaline in both 
cases, and had the same specific gravity, 1040.
