variable size, sometimes perfectly spherical, at other times 
oval, and whose dimensions, although uniform, may neverthe- 
less vary to a certain extent. According to some measure- 
ments that I attempted to make, I believed I had fixed them 
between 003 mm. and 006 mm. mean diameter. These are 
the elements which form the principal mass of the favous 
scabs. There are also to be found in variable, but always 
less considerable quantity, oval sporules, articulated end to 
end, forming a kind of chaplet, and straight short tubes 
filled, some with spores in process of development, others 
with fine and very brilliant granulations. 
After the free spores, the most abundant element is that 
named the mycelium , constituted by a mass of long tubes, 
usually flexuous, sometimes simple, sometimes, though more 
rarely, once or twice ramified, interlaced, and as if felted, 
and imprisoning in the meshes formed by their matting 
together a variable number of spores. 
This element, according to M. Robin, and as I have 
been frequently able to verify, is more particularly, aud 
indeed almost exclusively, found at the surface of the favus 
in contact with the animal’s skin. 
I have frequently examined the elements of the favus of 
animals, comparatively, with those of man, and could not 
perceive the slightest difference. 
The affection I am about to describe is accompanied, in the 
dog, by a lively pruritis, a symptom scarcely noticeable in the 
cat ; otherwise, it does not appear to exercise any prejudicial 
effect on the general health. The animals that are attacked 
eat, drink, play, and preserve their liveliness as if they were in 
perfect condition. 
Such is the disease as observed clinically. I have said 
above that I have made a certain number of experiments in 
order to assure myself of its contagiousness. This is the 
place to describe these experiments, a summary of which will 
complete the symptomalogic history of the affection.
