 smear preparation from the lesion stained with Wright's Romanowsky blood- 

 staining fluid. The ring-like bodies, with white central portions and containing 

 a larger and a smaller dark mass, are the micro-organisms. The dark masses 

 in the bodies are stained a lilac color, while the peripheral portions of the bodies, 

 in typical instances, are stained a pale robin's egg blue. The very dark masses 

 are nuclei of cells of the lesion. X 1500 approx. (Wright) (From photograph
