The diseases of infants and children . 195; 1902, LVI, 421.^Archiv f. Kiriderheilk., 1903, XXXVII, Arch. f. lunderh., 1902, XXXIII, 194. HUMAN MILK 93 ( ). Laurentius^ observed an instance where 3450 grams( ) were produced in a single day; and Rommel- the secretionof 4125 grams ( ) in one day.^ Colostrum.—The secretion occurring during the first 3 or 4 daysafter the birth of the child, and to some extent before its birth, is calledcolostrum. It differs from milk not only to some degree in chemicalcomposition, but in the presence of the colostrum corpuscles. Theseare cells, probably, as Czerny* believes, of lymphoid nature or are derivedin part from the mast cells (linger).^ They are 4 or 5 times largerthan the average leucocyte, are phagocytic, contain a nucleus, are filledwith fat-globules, and are at first very numerous (Fig. 16). They persistin constantly decreasing numbers until the end of the 2d week. A longercontinuation indicates that the milk is not in a healthy state. The. Fig. 16.—Milk axd half human milk; lower colostrum. Magnified. {Thiemich, Peers Lehrbuch derKlndcrhcilkunde, 1914, 6.) corpuscles reappear also when nursing is intermitted for a day or two,or when the breasts are not sufficiently emptied. Any breast-milk inwhich colostrum-corpuscles are present in decided numbers is liable todisagree with the infant. In addition to the corpuscles and fat-globules,mononuclear and polymorphonuclear leucocytes may be found. Thefat-globules of colostrum are very unequal in size. Alost investigators agree that the colostrum of the first few days beforemilk begins to be secreted is richer in protein and salts and poorer insugar and fat than the fully developed milk. The results from analysesmade by different investigators is shown in the following table: » Arch. f. 1912, LVI. 275. 2 Miinch. mod.
