ANALYSIS OF CONTINENTAL JOURNALS.

intact, others broken, with their serosity dried in small yellow 
crusts. In a purely anatomical point of view, it is a type of 
Herpes circinnatus. But in examining this erythematous spot 
more closely, there are observed five or six distinct points the 
size of a pin’s head, resulting from the accumulation of a special 
yellow matter at the base of each hair, which gives to these 
points the appearance of a veritable favus cup in miniature , in 
every particular similar to those which I watched and 
studied so carefully on myself at the commencement of this 
year. 
I detached one of the yellow points with a dissection 
needle, spread it conveniently on a glass slide, and examined 
it in the microscope; and at the first glance I lighted upon a 
spot where was seen a quantity of elements whose nature was 
not doubtful, for they were the elements of the Aciiorion 
Schonleinii: spores, sporophorous tubes, and mycelium mixed 
up in large numbers and sharply defined. 
The same day I sent this student to M. Rollet, whose 
examination confirmed in every particular the above diagnosis. 
Where and how had M. Bourotte acquired his malady ? 
This was a question less easily answered than in either of the 
other two cases. He had examined, studied, and handled 
the diseased rabbits several times, as well as the young rabbit 
that I had inoculated ; on the other hand, the rooms tenanted 
by the fourth year students were certainly as much haunted 
by diseased mice as those of the third year. It was no 
doubt from one of these sources that he had received the 
germs of the affection from which he was suffering, but it 
was impossible to decide which. 
There could be no hesitation, however, as to the true nature 
of the disease, and this was the capital point in the matter : 
it was the result of the germination on the human skin of 
the spores of the Aciiorion detached from the skin of an 
animal—rabbit or mouse; and, as with his comrades, this 
disease presented in him all the characteristics of Herjpes 
circinnatus. 
M. Bourotte was from this time submitted to the same 
treatment as his co-disciples. 
On July 27th the disease had made no progress; the 
patch was still very red, especially on its borders, but it had 
not extended, and the centre was a little paler. The same 
treatment was continued, only instead of three applications a 
day, only one was made. 
August 1st.—The disease is disappearing. I recommended 
M. Bourotte to change the dressings for a solution of nitrate 
of silver to be applied twice a day.
