PLATE XIV. 



MILK. 



Fig. 1. The globules of the healthy milk of a woman. 



Fig. 2. The globules contained in impoverished human milk, 

 which are seen to be smaller in size and fewer in 

 number than in ordinary milk. 



Fig. 3. An example of colostrum, on the first day, obtained 

 from a young woman aged 19, delivered of her 

 first child, and showing the size and arrangement of 

 the ordinary milk globules, as well as the structure 

 and appearance of the peculiar colostrum corpuscles. 



Fig. 4. The same colostrum of the same age, containing a 

 greater number of the colostrum corpuscles. 



Fig. 5. The same colostrum, on the same day, exhibiting the 

 great size of the cream globules, which appear 

 frequently to present rather the aspect of oil than 

 that of true milk globules. 



Fig. 6. The milk globules aggregated into masses, as occurs 

 in cases of engorgement of the breast.
