sporotrichosine than before the iodide had been administered 
to them. In either case the dermal reaction measured from 
5 to 15 mm. whereas the sporotrichosine reaction in the patient 
measured 5 to 7 em. 
While, therefore, a striking reaction may be elicited in these 
cases with sporotrichosine, it probably cannot be considered 
sufficiently specific to be of value for differentiating these or- 
ganisms. But it is to be noted that patients taking or not 
taking potassium iodide may react intradermally to these 
various strains of sporotricha and not to strains of blastomy- 
ces prepared in exactly the same way. Whether or not all 
cases will so react we do not know. 
SuMMaRY AND DISCUSSION 
It appears that the first case of sporotrichosis was reported 
by Schenck in 1898. The second case was reported in 1900 
by Hektoen and Perkins and the organism definitely identified 
lv comparison with that isolated by Schenck. Hektoen named 
the organism Sporothrix schencki. 
In 1903 de Beurmann and Gougerot reported the first case 
in France and the organism was named by Matruchot and 
Ramond Sporotrichum beurmanni. The work of the Ameri- 
can investigators published several years previously was not 
known to the French workers. 
On comparing the American strain sent to them by Hek- 
toen in 1906, seven years after its isolation, de Beurmann and 
Gougerot pointed out certain differences between this strain 
and their recently isolated strain. They noted certain differ- 
ences also between their own strains (strains a, b, ¢) but con- 
tended that these differences were not sufficient to justify ere- 
ating a new species. But the differences between their strains 
and Sporotrichim schenchii were sufficient, they contended. 
to justify a new species. The organisms, isolated later in 
North America and those found in South America and in 
Madagascar, they claim are the same as their organism, Sporo- 
trichum beurmanni. These were all isolated after they dis- 
covered and named the organism in France.
