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. Burdon Sanderson 
gives a résumé of the experiments made by the principal of 
these pathologists.
