CHANGES IN THE NON-PREGNANT UTERUS 103 



During the earlier stages of recuperation a variable, and 

 often a large, number of red blood corpuscles remain scattered 

 in the stroma, chiefly in the part nearest the surface. At a 

 later stage extravasated corpuscles are no longer seen in any 

 quantity, while numerous new vessels appear to have been 

 formed, presumably from pre-existing vessels. 



Polymorphs are no longer common in the bitch's mucosa 

 tissue, but leucocytes of other varieties are a characteristic 



polym.

feature. The following kinds have been observed : (1) 

 Coarsely granular eosinophil cells, with lobed nuclei. These 

 occur in the blood in cases of trichinosis, bronchial asthma, 

 sarcoma, osteomalacia, skin diseases, and other affections, but 

 are rare under ordinary conditions. (2) Basophil cells, with 

 simple nuclei and containing coarse granules, but never any 

 pigment. The number of granules varies, and in some of the 

 cells is very small. These basophil cells are evidently similar 

 to the mast cells of Ehrlich, and the plasma cells of Unna. Mast
