formed and opened to the exterior. A second similar case was 

 described by Hektoen and Perkins. Ruediger^ has. reported a 

 large series of cases of sporotrichosis and the references to Ameri- 

 can hterature will be found in his paper. The organisms are not 

 readily found in the pus by microscopic examination and seem 

 to exist there only as conidia. In cultures a branching myceUum 

 with clusters of conidia is produced. Dogs are susceptible to 

 inoculation.

Sporotrichium Betmnanii.^ — De Beurmann and Ramond at 

 Paris in 1903 found this parasite in a case of lymphangitis. It 

 seems to be different from the organism described by Schenck 

 but may ultimately prove to be the same species. 



Cryptococcus Gilchristi.— Doubly contoured yeast-like cells 

 which multiply by budding in human tissues, were first discovered 

 by Busse and Buschke^ in 1894, in a case presenting abscesses in
