ANIMAL VACCINE. 
Recueil de Medecin Veterinaire. 
One great advantage in favour of animal vaccine is, that 
it can be obtained almost ad libitum, without the risk of having 
a short supply in case of emergency, when, on a sudden out- 
break of an epidemic of smallpox, general vaccination has to 
be resorted to. 
At the beginning of February, 1869, the Steamer “ Floride,” 
of the Transatlantic Steam Packet Company, doing the service 
between Panama and Saint Nazaire, returned to France with 
several patients attacked with smallpox. 
The malady had been introduced on board by a passenger 
who embarked at Columbia. This passenger came from the 
coast of the Pacific, where the malady prevailed from Valparaiso 
to Panama, an extent of 1800 leagues. It was not till twelve 
days after his embarkation that he felt the first symptoms of 
the malady. Notwithstanding the most complete isolation 
of the patient, the smallpox spread to the crew and officers 
of the ship, only the captain and the doctor escaping ; eight 
deaths occurred from it. 
The arrival of the “Floride” in France preceded only a 
few days the time of the departure of another steamer, the 
“ Nouveau-Monde,” for the Isthmus of Panama. At the 
thought of the danger which the crew, &c., of this steamer 
would run at its arrival at Columbia, the Company decided on 
having the whole of them revaccinated ; but this was a ques- 
tion of revaccinating from 400 to 500 persons, and there not 
being vaccine enough on hand for the purpose, they were 
on the point of giving it up, when it occurred to them to apply 
to M. Lanoix, and to ask him for 200 tubes of vaccine. 
M. Lanoix considered that it would be more expedient to 
inoculate a heifer to be put on board in order to revaccinate 
the crew. On the 5th of February, a heifer was conse- 
quently inoculated with 150 punctures, and was put on board 
the “ Nouveau-Monde,” which left on the 8th for St. 
Nazaire.
