THE PHYSIOLOGY OF REPRODUCTION 



is said by Heape (but not by van Herwerden) to be the case in the 

 monkey. 



During the earlier stages of recuperation a variable, and often a 

 large, number of red blood corpuscles remain scattered in the stroiua. 

 chiefly in the part nearest the surface. At a later stage extravasated 

 corpuscles arc no longer seen in any quantity, while numerous new 

 vessels appear to have been formed, presumably from pre-existing 

 vessels.

but leucocytes of other varieties arc <i characteristic feature. The 

 following kinds have been observed: fl) Coarsely granular eosinophil 

 cells, with lobed nuclei. These occur in the blood in cases of

 and other affections, but are rare under ordinary conditions. (2) 

 r.'isophil 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 busophil cells are evidently similar 

 to the mast cells of Khrlicli and the. plasma cells of I'nna. Mast 

 cells are said to be often found in inflammatory areas, and are 

 described as occurring in the stroina tissue of turnouts in association 

 with plasma cells, and also in the peripheral circulation in cases of
