CHANGES IN THE NON-PKEGNANT 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 pi'e-existing vessels.

featvu'c. The following kinds have been observed : (1) 

 Coarsely granular eosinophil cells, with lobed nuclei. These 

 occirr 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 grantdes, 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 EhrUch, and the plasma cells of Unna. Mast
