to Sporotrichum beurmanni, deed identical with certain pleo- 
morphic forms of the latter. They make the significant state- 
ment in this connection: ‘‘Plusicurs de ses pléomorphismes 
s‘identifient au Sporotrichum Sehenki et au Sporotrichum 
Beurmanni, voire méme au Sporotrichum Gougeroti. Cette 
unification dans les pléomorphismes est la meilleure preuve 
dune commune origine de ces germes.’’ Their position seems 
to be that this organism, the American organism Sporo- 
trichum = schenchii, and the Sporotrichum beurmanni were 
originally one and the same organism, and certain strains 
later developed pleomorphic characteristics leading to new 
varieties. 
A new pathogenie sporotrichum, Sporotrichum councilinani, 
described very recently by Wolbach, Sisson and Meier? of 
Boston was found in a case of acute arthritis of the knee 
fellowing injury. From their deseription it appears quite 
different from all other strains of Sporotricha. They 
summarize the distinguishing features as follows: ‘‘(1) 
its pleomorphic growth, characterized by a free aerial growth 
of hyphae; (2) the abundant spore formation, large size of 
the spores and absence of lateral spore clusters, and (3) the 
occurrence in lesions as septate, branching filaments.’’ The 
last character is especially significant. The clinical history 
and the character of the lesion in the patient are also of in- 
terest and are possibly of importance for differential purposes. 
For the purpose of this paper [ think we may eliminate 
Sporotrichum dori as being quite diffarent from the other 
sporotr:vha; also Sporotrichum councitinant, The very rare 
cases of so called Sporotrichum indicum, Sporotrichum jean- 
selmet and Sporotrichum gougeroti ave much more closely re- 
lated to Sporotrichum beurmanni, the first two indeed being 
probably identical with it. The existence of these very rare 
varicties is here recognized but this fact is only indirectly re- 
lated to the main question at issue here, namely, the possible 
identity of the organisms causing sporotrichosis as commonly 
observed in America and in France. 
In the further analysis of this question it will be desirable
