Furthermore, the stomach of a calf underthree days old secretes very little rennet. The sugar ofcolostrum is said to be principally dextrose, the sugarfound in the blood stream. A peculiar and distinguish-ing constituent of all kinds of colostrurii is the colostrum. Fig. 49.—Normal Human Milk. (Jewett.) Fig. 50.—Colostrum Corpuscles. (Jewett.) corpuscles, which are thought by some to be modifiedwhite blood corpuscles. For a week or two after birth there is a continualgradual change in the character of the proteids and sugarof the mammary secretion, the constituents of normalmilk which require digestion, displacing those of colos-trum ; during the same time the secretion of the digestivejuices commences in the young animal. This process seems to take place in all animals thatsecrete milk, but when the flow of milk is established awide diversification in digestive processes and characterof the milk is seen. The milk of animals whose digestion FOOD FOR ADULTS INAPPLICABLE. 205 takes place principally in the stomach forms solid curdsthat leave it with difficulty (cows, goats, and sheepsmilk). The milk of animals whose digestion is principally in-testinal forms soft gelatinous curds which easily pass intothe intestine (mares and ass milk). The hum
