School, was charged with the duty of attending to, and dress¬ 
ing the three diseased rabbits mentioned in the preceding 
observation. Knowing, from experience, the danger that 
was incurred through being in contact every day with pa¬ 
tients of this kind, I recommended him to take all precau¬ 
tions with regard to keeping his skin free from the debris of 
the favus crust which might adhere to his clothes. But I 
also knew that all the precautions in the world would not 
ensure complete security; and, therefore recommended him to 
watch attentively, and inform me whenever he saw anything 
on himself of a suspicious nature. 
A month passed without our fears being realised, but on 
the 8th of July M. Maherault told me that he had remarked 
two suspicious looking patches, one situated on the left thigh, 
the other on the chest, a little below the right breast. 
I examined these lesions carefully, and although 1 could 
discover no trace of the parasite, I sent him next day to Dr. 
Roilet, who, not being able to arrive at a sufficiently satis¬ 
factory diagnosis from the character of the patches, advised 
that the malady should be allowed to take its natural course 
for some days, at the same time watching it. This was done. 
On the 10th a new patch appeared on the chest, a little 
beneath the right breast, and nearer the median line than the 
first. On the 12th a fourth showed itself on the left side of 
the neck, below the ear. 
From the 12th to the 17th of July these eruptions were 
examined every day, and their progress was attentively fol¬ 
lowed ; the cryptogamic elements which we knew ought 
to be present were sought for, our search being aided on 
several occasions by Dr. Roilet; at length, after repeated 
examinations, we succeeded in clearly recognising the pre¬ 
sence of these elements. It was at this stage of the malady 
that I had the honour of exhibiting this youth to the Society. 
After this convincing proof as to the nature of the affection, 
it was decided, in concert with M. Roilet, that M. Maherault 
should be submitted to an antiparasitic treatment. Every 
day all the diseased places—even those on the mastoid re¬ 
gion, which had been cauterised on the 13th with solid nitrate 
of silver—were to be dressed with the following liniment: 
Corrosive sublimate . . .50 centigrammes. 
Glycerine . . . .50 grammes. 
Alcohol q. s.
