History of Animal Plagues. 491 



looked upon as a typlioid fever, accompanied by inflammation 

 and 2;an<rrene of the abdominal viscera, and of the luno-s. Bv 

 manv, however, it was regarded as identical with the Cattle 

 Plague, which yet lingered in France, and which also prevailed in 

 many provinces of Austria during this and the following year. 



As Vicq-d'Azyr's celebrated Memoir on this outbreak has 

 always been considered a model report, and as it is now exceed- 

 ingly scarce, a translation of it may not be uninteresting to the 

 student. It is particularly worthy of notice how closely the 

 symptoms correspond with those of Cattle Plague, and it might 

 have been that careful investigation would have revealed a con- 

 tagious orio-in for it, and have established the identity of the two 

 maladies. 



' The epizootic disease which is the subject of this Memoir, 

 although very deadly and contagious, has been arrested in its 

 progress, without having recourse to the extreme measure that 

 necessity sometimes renders indispensable, and that the nature of 

 the malady demands in certain cases. ^ The treatment which 

 has been adopted at my suggestion has, in the majority of in- 

 stances, been followed by success; these two circumstances, then, 

 are sufficient to make the description of this epizouty interesting. 

 I shall show, in different articles, all that which concerns it : the 

 topography or situation of the localities in which it has reigned; 

 its local causes; its origin and increase; its symptoms; its ac- 

 cidental features ; the internal lesions which have been observed 

 in animals that have died from it; its connection with other 

 analogous disorders; the curative measures and those of a pre- 

 servative kind ; the manner of disinfecting ; the disposition of 

 the military cordons and other auxiliaries; and the general 

 tableau of the numbers of animals which have died and those 

 which have been cured : — all these will be shown in succession. 

 Besides the advantage which will result from this method, there 

 will be manifested, in these details, to those medical men who 

 may undertake similar labours, a just and precise idea of the ob- 

 jects they will have to keep in view.
