IDENTITY OF AMERICAN AND FRENCH SPOROTRICHOSIS 109 
now they can no longer be considered rare. Ruediger’ 
gathered together and analysed all the cases in the United 
States in 1912. He found 57 in which the diagnosis had been 
made with reasonable certainty. Since then the literature 
each year has furnished a considerable number of additional 
reports. Many cases have no doubt not been recorded in the 
literature. The writer is aware of several in which cultures 
were obtained and identified as Sporothrixr schencku but never 
reported. 
Ruediger called attention to the interesting fact that the 
disease oceurred chiefly in the Missouri River Valley. Five- 
sixths of the 57 cases were from this locality,—the others 
being scattered more or less diffusely over the country. North 
Dakota, which furnished 22 authentic cases, seems to be the 
chief focus of human infection in this country. Kansas has 
also furnished a large number of cases. A map showing the 
location of the cases in the United States accompanies Ruedi- 
ger’s paper and brings out strikingly the geographical dis- 
tribution. However, K. F. Meyer?’ has more recently analysed 
the data, especially those dealing with the relation of animal 
and human sporotrichosis in this country. He shows that 
ag new cases appear it becomes increasingly evident that the 
disease is widely distributed, though certain localities like 
the Missouri River valley furnish the great majority of the 
cases. It has been reported from the following states: Mis- 
souri, Kansas, Iowa, Nebraska, Texas, Virginia, West Vir- 
ginia, Ohio, New Jersey, District of Columbia, South Dakota, 
North Dakota, California, Illinois, Pennsylvania, New York, 
Minnesota, Wisconsin, Indiana, Montana and Michigan. Two 
cases have been reported from Canada. 
Sporotrichosis has appeared in horses in several localities 
in the United States. The disease was recognized clinically 
in horses some time before it was accurately studied bacter- 
iologically in this animal. Horses were found in 1908 or be- 
fore in North Dakota suffering from what was then taken to 
be mycotie lymphangitis. From the description and the
