but all he said was that our observations had been extensive and 
minute, and they had seen nothing approaching to it in a horse 
or dog, or any other animal except the sheep.” Five years before 
these words were spoken, the horse-pox had been carefully de¬ 
scribed in English veterinary literature, and the malady had not 
only been observed on the Continent, but in England and America, 
and its existence proved over and over again beyond a doubt. 
Dr. Loy’s pamphlet was translated into French by Dr. Carro, 
soon after its appearance in England, and published in the “ Bib- 
liotheque Britannique” in the year X (vol. xxi.). Carro was a 
great admirer of Jenner, and he dwelt with much force on the 
clearness and precision of Loy’s experiments, as furnishing in¬ 
dubitable proof of the justness of the opinion of the introducer 
of vaccination. But Carro, in his eulogistic comments on Loy’s 
work, remarks that the French vaccinators had experienced great 
difficulty in understanding what the English term “ grease ” really 
meant, some thinking it was javart (tistula of the foot from in¬ 
jury), or eaux aux jambes (simple inflammation of the sebaceous 
follicles— vulgo , common “ grease ’’)—an uncertainty,” adds Car¬ 
ro, “ which shows what little care the English have observed in 
describing the grease , and is probably the cause of the small prog¬ 
ress this interesting portion of the veterinary art has made among 
them.” The French veterinarians and medical men who tried 
Loy’s experiments had no better success than those in England 
who did not have recourse to the eruptive disease for inoculating 
material; consequently, in France, also, Jenner and Loy were 
believed to be in error, and nothing more was thought of horse- 
pox or “ constitutional grease.” 
But it is curious, in the midst of this incredulity, to find Carro 
himself adducing most valuable confirmatory proof of the cor¬ 
rectness of Jenner and Loy’s statements, in a letter addresssed to 
Professor Pictet, of Geneva, in 1803, and published also in the 
“ Bibliotheque Britannique.” In this letter Carro writes : “ Les 
mareehaux-ferrants de Salonique distinguent trois sortes de javart: 
V ecrouelleux, le phlegmoneux , le variolique. Ce dernier parait 
etre le memo quo le grease constitutionnel du docteur Loy, car il 
est accompagne d’une eruption semblable a la petite veriole. Aussi,
