ANALYSIS OF CONTINENTAL JOURNALS. 
for it is probable that when I examined the parts the parasite 
had not had time to germinate and multiply in the manner 
we see it when fully developed.” 
Some time afterwards, in May or June, 1866 (the precise 
date was unfortunately mislaid), the clinic of our school 
again gave me an opportunity of studying the Tinea in a 
young cat belonging to a well-known architect of this town. 
The servant who brought this patient also showed on herself 
two erythematous patches, one on the neck, the other on the 
left forearm. As before, I sent this girl to Dr. Rollet, who, 
as in the preceding cases, was led to believe the disease to be 
Tinea commencing, and attributed it to contagion. 
I do not conceal from myself what is wanting in these 
facts to render them entirely demonstrative, as in neither of 
the three patients was the parasite to be found ; nevertheless, 
it seems to me that we may, without much temerity, assign 
to the disease in these three persons a certain degree of 
parentage with the malady in the young cats, with which 
they lived in habitual contact. This was also the opinion of 
M. Rollet, whose competency in such a matter is well known 
to the scientific world ; and this opinion appears to me to 
acquire a high degree of probability when we bring these 
facts to bear upon the interesting observations of Mr. Draper, 
as cited above, and especially the conclusive experiment of 
M. Tripier, also alluded to. 
In addition, I am now in a position to support this evi- 
dence by a new and most conclusive fact, which will be 
adduced hereafter. 
From the foregoing it therefore results : — * 
1. That animals, and particularly the dog, cat, and mouse, 
are susceptible of contracting Tinea. 
2 . That they may contract it by direct contagion from 
animal to animal ; but that they may also, and the cat espe- 
cially, receive it through their relations with diseased chil- 
dren. 
o. That the mouse being liable to the malady, it is very 
probable that this little rodent most frequently gives it to the 
cat. We all know how much young cats love to play with 
the living mice brought to them by their parent. 
4. That young cats affected with the disease may, in their 
turn, transmit it to children, who, as we are all aware, amuse 
themselves by fondling these gentle creatures. 
5. By their contact with the young cats, which are also 
often attacked by favus, children are exposed to contract this 
affection, which is as pertinacious as it is repulsive ; from this 
circumstance, which has hitherto scarcely been suspected.
