palate and right tonsil ; that on the latter was of some size 

 and depth, and had an elevated border.' The symptoms 

 and appearances in this case led Bossi to conclude that the 

 animal was suffering from diphtheria, or perhaps more 

 correctly speaking, from laryngo-pharyngeal angina of 

 pseudo-membranous or croupal character. The dog died 

 on the third day, from suffocation, after having had some 

 convulsive movements. At the necropsy, the mucous 

 membrane of the fauces was found in a pulpy condition 

 and denuded of epithelium. Here and there the mem- 

 branous exudation presented the appearance of compact 

 thick, adherent excrescences. The ulcerations were blackish 

 and very deep. The inflammation extended to the mucous 

 membrane of the pharynx and larynx. The heart and 

 lungs, which presented a blackish, flabby appearance, con- 

 tained pitch-like blood and several fibro-albuminous con- 

 cretions. 



" This is a remarkable case, and one well worth remem- 

 bering by members of the veterinary profession, many of 

 whom have a great deal of practice among dogs ; animals 

 which, from their intimate association with mankind, and 

 from their habits and tastes, would be the most likely to 

 receive the contagion, if it be really transmissible. 



" Experimental evidence as to the transmissibility of 

 diphtheria from man to animals is not very abundant, but it 

 appears to be sufficiently clear to enable careful patholo- 

 gists to come to a decision ; as several have concluded, from 

 the results of their attempts to produce the disease in 

 animals, that the morbid process generated in these by 

 inoculating portions of diphtheritic concretion is not simply 

 what has been designated a ' mycosis,' but is, in reality, the 

 specific malady itself. In his report on the ' Pathology of 

 the Infective Processes,' just published in that of the 

 • Medical Officer of the Privy Council, Dr. Burden Sanderson 

 gives a resume of the experiments made by the principal of 

 these pathologists.
