TRANSLATIONS FROM CONTINENTAL JOURNALS. 249 
This is an eruptive malady. The old ideas are that the 
vaccine has been engendered by the grease of the horse, 
but it is not grease which has recently been also observed 
and described by those gentlemen of Toulouse. The result 
would be that, from the observations made at Toulouse, con¬ 
tagion is less frequently produced by direct inoculation than 
from the hands and arms of the men coming in contact with 
horses’ legs affected with grease and afterwards with the teats 
of cows. It is well known that the malady is called grease 
by the English, and that the description of it by Percival is 
identical with that which, in France, is described as eau au 
jambes. In Italy, in 181 1 , Sacco took for grease a furunculous 
affection which is cdWed javart in France and giovardo in Italy ; 
but, what is singular, Sacco reports cases of transmission of 
javart from the horse to the cow. In 1840, M. Verheyen 
published in the ^ Memoirs of the Belgian Academy,’ a paper 
on the primitive vaccine, in which he cites facts observed by 
M. Hertwig relative to cowpox being produced by a gangren¬ 
ous affection which certainly was not grease. Thus, then, as 
stated by M. Bousquet, the horse would be vaccino-genetic. 
Respecting this there is no doubt; but is there one or 
several maladies which produce cowpox, or is it incumbent 
to institute fresh experiments to ascertain whether there is 
e, and which that is ? 
M. BepauL —I am astonished that M. Bouley, instead of 
criticising and judging the observations produced, should 
have contented himself by repeating them; he does not even 
seem embarrassed by what appears contradictory or singular in 
them. For my part, I confess that the idea of the cowpox pro¬ 
ceeding from different maladies deranges all my knowledge of 
general pathology. Gentlemen, I was a niember of this com¬ 
mission of Toulouse. The question was this: does the grease in 
the horse produce the cowpox ? On the 29th of March, I860, 
the Union Medicate published a letter of M. Fontan, in which 
it was stated that at Riennes, M. Sarrans, veterinary surgeon, 
had above one hundred horses affected with grease,* and 
«I determined,” says M. Leblanc, “ to make the journey to Toulouse on 
the 6th of June, 1861, because I read in the letter of M. Fontan (published 
in the Unio?i Medicate) that the grease in the horse’s legs had produced the 
vaccine in the cow—a circumstance which seemed extremely strange. I 
could not accord with the observations made in my presence by M. Bousquet, 
wit hout having seen the disease by my own eyes. This, I repeat, was the sole 
cause of my journey. I departed with the conviction that I was going to 
see a number of horses wliicli MM. Lafosse and Sarrans believed to be 
affected with grease. M. Fontan w'ould not have guessed at the existence 
of this disease had it not been so designated by that name to him by M. 
Lafosse. In a letter written to M. Renault by M. Lafosse, the question is 
t ill one of grease.”—This letter was read on the 26th of June, at the Academy.
