IDENTITY OF AMERICAN AND FRENCH SPOROTRICHOSIS 115 
Die Frage kann nur entschieden werden durch Vergleich der 
Original-kulturen von Schenck und Hektoen. Entschliesst man 
sich, diese dritte Hypothese einer Unitat des Sp. Schencki und 
des Sp. Beurmanni anzunehmen, so wurde trotzdem die Tatsach® 
bestehen bleiben, dass dieser Parasit in zwei Typen sich darstal- 
len kann; als Sp. Schencki, der seltener Typus, welcher einzig 
von den amerikanischen Forschern im Jahre 1898 and 1900 be- 
schrieben worden und von welchem der Stamm MHektoen-Gou- 
gerot eine Abart bildet (Sp. Schencki-Beurmanni var. Schencki), 
und schliesslich als Sp. Beurmanni, ein sehr verbreiteter Typus, 
der zum ersten Mal von Matruchot & Ramond im Jahre 1903- 
1905 und spater im Jahre 1906 von Beurmann & Gougerot 
studiert worden ist (Sp. Schencki-Beurmanni var. Beurmanni.) 
From the above statements it is evident that Gougerot him- 
self concedes the identity of the French and the later Amer- 
ican strains and I entirely agree with him on this point. I 
have examined several French strains very carefully and 
compared them with later American strains from man and 
horses without noting any essential points of difference. Ad- 
mitting then that the French strains and the later American 
strains are identical, the question resolves itself into a com- 
parison of the disease and organisins as observed by Schenck 
and by Hektoen on the one hand and the French and later 
American disease and organisms on the other. These latter, 
it is to be noted, are conceded to be identical with the strains 
from South America, Madagascar, and the other foci men- 
tioned above. If it is shown that they are identical with 
the Schenck-Hektoen strain, they should all be called Sporo- 
trichum schenckit. If they are different, they would be called 
Sporotrichwn beurmanim and the strains of Schenck and Hek- 
toen would remain as isolated and unique organisms differing 
from all other described sporotricha. 
CoMPARISON OF THE Two CASES OF SPOROTRICHOSIS OBSERVED 
By SCHENCK AND BY HEKTOEN AND PERKINS WITH 
THE LATER AMERICAN CASES 
Clinically these two cases were typical ascending gumma- 
tous sporothrichosis identical in every way with the many 
cases observed later by the French and by many observers
