AND TYPHUS.

a general inoculation of the animals, or would the authorities 
sanction such a proceeding ? These are questions of the greatest 
interest, and merit our most serious attention. 
M. Dupuy, in a work recently published, recommends inocu- 
lation in the typhous epidemic of cattle ; and he hesitates not to 
say, that it is, in point of fact, nothing more or less than a vario- 
lous cachexy, or eruption fpicotte) of cattle; that it resembles 
variolous affections in the human being, the horse, the sheep, 
and the swine ; and, relying on the resemblance between or the 
identity of the maladies, and upon the results of his own experi- 
ments, he concludes that inoculation is a measure that should 
be adopted in preference to all others on the appearance of this 
disease. Such an opinion, unhesitatingly delivered by a man 
like M. Dupuy, who has seen and studied the disease, and has 
successfully practised this inoculation, must have considerable 
weight with veterinary surgeons, and with the municipal autho- 
rities. It then becomes our duty to examine this matter in de- 
tail, and, first of all, to inquire into the identity or analogy exist- 
ing between typhus and variola, whether mild or malignant. 
Typhus — is it a variolous affection ? 
Ranrazzini in 1711 described typhus under the name of the 
small-pox of cattle*. 
The physicians of Geneva in 1714 attempted to prove the ana- 
logy which existed between this disease in cattle and the small- 
pox in the human subject^. 
Herment, physician to the King of France, Drouen, surgeon 
to the Body-Guard, and Guillot, physician at Besan^on, at- 
tempted to shew the same analogy. 
Layard made the same observations in England in 1757, and 
Vicq-d’Azyr designated the epizootic typhus of 1774, 1775, and 
1776, under the name of variolous typhus. 
In order to ascertain the analogy or resemblance that may 
exist between these diseases, there seems no better way than to 
form a synoptical and comparative table of the symptoms, dura- 
tion, and termination of the one and the other. 
The typhoid epizootic presents always at its commencement, 
and at its full development, a serious character that cannot be 
mistaken. It destroys the greater part of the animals which it 
attacks ; but after a certain time it becomes less obstinate and 
destructive. Strictly speaking, we might distinguish two species 
of typhus — the one malignant and irregular, the other mild and 
regular ; there are also two varieties of small-pox answering to 
the same description.
