SUMMARY. 
My observations have led me to conclude that a number of forms of 
chronic ulceration of the skin are to be encountered in Manila, among 
which (after excluding certain ulcerative lesions of syphilis, yaws, leprosy, 
and lupus) there still exist at least several types of different etiology. 
A somewhat rare form is evidently of blastomycetic origin, in which the 
torule encountered have somewhat the appearance of the forms which 
have been described in certain cases of Oriental boil or sore as species of 
protozoa related to the Donovan-Leishman bodies.
