Cryptococcus hominis has recently come into rather general use as the name for the pathogenic organism of this disease.

As early as 1901 Vuillemin2 first used the term C. hominis for the yeastlike organism found in the lesions of European blastomycosis. Frothingham,3 studying a tumor-like mass in the lung of a horse in 1902, discovered and described the yeastlike fungus causing the lesion. After cultural examinations and animal inoculations, he concluded the pulmonary lesion in the horse was caused by a torula. There seems little
