ated pyenotie cells. Other areas show many polymorphonuclear leucocytes and 
degenerating cells. 
In the third portion of tissue removed, the only additional pathological con- 
dition is the presence, deep in the corium, of considerably denser fibrous tissue 

No. 237. — Photomicrograph. The numerous blood vessels do not show characteristics of 
syphilitic vessels. Their dilated condition is apparently due to the density of the tissue 
surrounding them. There is marked infiltration of the corium. (Gangosa) 
containing collagen fibers. In none of the sections were giant cells observed. 
The sebaceous and sweat glands and the hair follicles were retained and appear 
normal. 
While it was anticipated that acid-fast bacilli (leprosy bacilli) might be en- 
countered in some of these lesions, none were found in any of the sections. No 
spirochaetes were demonstrated in the tissues by Levaditi’s stain. While cocci 
were found on the surfaces of the suppurating lesions, neither spirochaetes nor fusi- 
form bacilli were found. The histopathological condition present does not sug- 
gest leprosy, particularly, nor does it especially suggest syphilis, particularly in 
the absence of marked vascular changes. Modifications more or less characteris- 
tic of yaws were present, but all that can definitely be stated from the study of
