628 ON THE VARIOLA OR SMALL-POX OF SHEEP. 
loured ; sometimes ulceration of the velum palati, epiglottis and 
the interior of the larynx; the pituitary membrane thickened, 
livid, engorged, ulcerated, and sphacelated; sanguineous conges- 
tion in the nasal fossa ; mucous membrane of the trachea and 
bronchi inflamed, ulcerated, and gangrenous ; sometimes containing 
albuminous concretions and false membranes; the pleura and 
sometimes the mediastinum inflamed ; effusion of water into the 
thorax, and even into the pericardium ; the lungs diminished in 
volume, discoloured, tuberculous and hepatised; the heart soft- 
ened and pallid ; the internal surface of the rumen rugged ; the 
reticulum or maniplus distended, and its membrane or internal 
coat dry ; the abomasum or fourth stomach distended with gas ; 
the mucous follicles of its internal coat more or less developed ; 
colon in the same state ; the liver tuberculous, adherent to the 
diaphragm, its substance of a lively red, sometimes of a deep 
brown colour ; the gall-bladder flabby, distended, blue or black ; 
spleen, sometimes voluminous; kidneys pale, discoloured, de- 
prived of their fatty covering, and their surface sometimes studded 
with little white bodies. 
Professor Simonds, of the Royal Veterinary College, London, 
in an interesting paper published in The Veterinary Record of 
this month, and which I would recommend to the perusal of all 
flock-masters, has given the following as the post-mortem appear- 
ances presenting themselves in one that died soon after its arrival 
at the College : — “ The skin was thickly studded with the eruption 
in its nodular or tuberculous form. A section of some of these 
nodules being made, shewed that they extended to the subcuta- 
neous structure, presenting an appearance not very dissimilar to 
warts. The cellular tissue immediately beneath the integument 
was infiltrated with blood ; the conjunctiva and Schneiderian mem- 
brane were highly injected, as was the mucous lining of the trachea 
and bronchi ; and the vessels of the lungs were filled to engorge- 
ment, which evidently was the immediate cause of death. The 
other viscera, both of the thorax and abdomen, shewed no traces 
whatever of diseased action.” 
According to the experiments of the French veterinary sur- 
geons, none of our other domesticated animals nor poultry, nor 
even the monkey-tribe, are susceptible of the action of the small- 
pox of sheep, neither by inoculation nor infection ; but the mon- 
key, from his close approximation to man, will take, both by con- 
tagion and infection, the human small-pox. 1 have seen several 
cases of what might be called small-pox in the horse, as far as 
external character went, but still it did not propagate itself to 
others by infection ; — how far it would have done by inoculation, 
I do not know.
