round, oval, bean-shaped, or nodular, ranging from very small 

 (1 to 2 /A), to an enormous size (5 to 200 ^ according to Zimmer- 

 mann). These bodies show no concentric formation, or radial 

 stripes. They usually appear during abnormal activity of the 

 gland, and are found in colostrum, in stasis of the milk, in mastitis, 

 in the inactive glands of older animals, etc. Their varied thickness 

 makes active turning of the micrometer screw necessary. 



These corpora amylacea (according to Siegert, corp. flava in contra-distinction 

 from corp. versicolorata, are the same as amylacea) were seen by Herz, Ottolenghi, 

 Iwanoff, and later described by Martin, Lenfers, Winkler and Zimmermann. Wederhake

confirmed their occurrence in the colostrum of women, and compared them with the corp. 

 amylacea of the prostate gland. 



A section offers the best opportunity for the microscopical 

 study of the nature of these bodies. In preparations of acute 

 mastitis, their development is especially clear. Around small 

 flakes of proteids, possibly precipitated nuclear or cell fragments, 

 layer after layer will be formed until a concrement results, which 

 may even fill the entire alveolus. Lime and salts of magnesium are 

 later absorbed by this basic structure of concentric layers, and fine
