administrations, in order to await the effects of my experiment. 
The flow of urine had certainly diminished, and the animal fre- 
quently endeavoured to assume the usual position for staling, al- 
though at these times but little urine, in a thin stream, and that by 
jerks, was voided. Encouraged by this slight success, I again 
gave sugar of lead with the already-mentioned accompaniments, 
beginning with five drachms, and in a few days increasing it to 
six drachms. 
The flow of urine continued to diminish, and at length almost 
entirely disappeared. The animal dunged and urined more natu- 
rally, although I still observed that, towards the close of the 
operation of urining, he appeared to experience some difficulty ; 
curved his back, stretched out his limbs, and ejected the urine 
by jerks, accompanied by a groaning sound. The horse did not 
appear to experience any pain when the loins in the neighbour- 
hood of the kidneys were pressed. The urine had returned to 
its natural state. During the whole course of treatment the ani- 
mal never lost its appetite. I now discontinued all treatment, and 
in the course of a few days the functions were naturally per- 
formed. 
While the medicine was given, the horse was only moved now’ 
and then ; but I caused him to be ridden out for half an hour every 
day, and gave him his usual rations. 
I kept him in the whole thirty days, and then returned him to 
the owner in perfect health and good condition. Nineteen months 
have since elapsed, and not the slightest recurrence of the evil has 
been observed. 
ON THE TRANSMISSION OF SOME MALADIES FROM 
THE INFERIOR ANIMALS TO MAN. 
By M. LAVERGNE, of Toulouse . 
My intention is not to write a history of contagious maladies — I 
wish only to speak of their transmission from animals to man, in- 
dicating the different opinions of authors on this matter, and adding 
to some old facts a few new ones, which, by their nature and their 
rarity, have appeared to me worthy to be known. 
I shall have little to say of the vaccine disease, which, as is 
witnessed by all medical men and veterinary surgeons, has the 
property of transmitting itself to man by inoculation, and of pre- 
serving him from the variolous disease. It is to Jenner that we 
owe the discovery of the cow-pox and the benefits of its applica- 
tion. I would remark, however, that, in passing from the cow to
