ANALYSIS OF CONTINENTAL JOURNALS. 595 
them perfectly distinct in the tissues or the blood of animals, 
in which they may remain two months without being notably 
altered. Lastly, they are the hundredth part of a millimetre 
in diameter, about equal in volume to that of the white glo- 
bules of the blood, and much superior to that of the red 
corpuscles. 
On the 15th August, 1868, I injected, with Pravaz’s 
syringe, four drops of water charged with a great number of 
the spores of the ustilago maidis into the substance of the 
abdominal parietes of a young guinea-pig. The animal 
having been killed six days afterwards, the spores of this 
ustilago w^ere discovered in the lungs and liver, but more 
especially in the brain, where they were found in large num- 
bers chiefly in the grey matter. There were also some in the 
interior of the eye. 
On the 24th August, 1868, 1 injected in the same manner 
into the abdominal wall of a very young guinea-pig, three 
drops of water densely charged with the maize ustilago. Its 
organs having been examined five days after, I found many 
spores in the blood contained in the heart and in the lungs, a 
small number in the brain and liver, and some in the spleen, 
the supra-renal capsules, and the kidneys. 
Recently, I have confirmed these results by new experi- 
ments which I shall communicate to the Society when they 
are terminated. I may, however, state that I have obtained 
the transport of the spores of the maize fungus in the guinea- 
pig about once in every two attempts. As might have been 
expected, the lungs were the first to contain them. In one of 
the animals which had been injected about six weeks, none 
were found in the lungs, but a great number were discovered 
in the brain. 
At the Seance of the Academy of Sciences, held at Paris 
on the 11th of last July, honorable mention and a sum of six 
hundred francs were awarded to the veterinary professors, 
MM. Tripier and Arloing, for their discoveries relative to the 
cutaneous sensitive nerves. M. Saint-Cyr, professor at the 
Imperial Veterinary School of Lyons, was also awarded a 
prize of a thousand francs as an inducement for him to con- 
tinue his researches on Tinea favosa in the domestic animals. 
The paper detailing his investigations into the history, nature, 
and transmissibility of this malady was read to the Academy 
in 1869, and published in the ‘ RecueiP for that year. It is 
so interesting and important in a pathological point of view, 
and the subject is at the same time dealt with in such a lucid 
and scientific manner, that we purpose giving a translation
