of darker colour than the neighbouring parts, but without 
the least trace of ulceration. In the mouth the mucous 
membrane of the tongue healthy. The only apparent 
lesions, against the first and second left molars and the 
third and fourth right, were two large deeply penetrating 
ulcerations extending even through to the skin, which is 
itself ulcerated. 
The ulcerations covered with a black detritus of repulsive 
odour, and with difficulty separable from the neighbouring 
tissues, the gangrenous part about two millimetres in thick¬ 
ness, and tearing somewhat readily on traction. Underneath 
this dead layer a yellowish border, of about half a millimetre 
in thickness, very tenacious, in it. One can recognise with 
difficulty the presence of muscular fibres, cellular tissue, and 
the deeper structures of the skin. All the surrounding 
structures of the cheek are the seat of an intense congestion. 
The two ulcerations from 3 to 4 centimetres in diameter, 
and with their depth decreasing towards their margins. 
The gums also the seat of a violent irritation. Within the 
third lower right molar, and a little below the position 
where the gum has been pierced or rather cut by the free 
border of the tooth, which is scarcely cut, a small tubercle 
about the size of a lentil, of a whitish colour, solid, and 
adherent to the membrane. On raising this the dermis of 
the mucous membrane is exposed, which is of a bright red 
colour, from its circumference to the seat of mortification. 
This evidently is the commencement of a mortification 
which, had the animal lived, would have assumed the cha¬ 
racters of the others. The pharyngeal glands are enormous, 
red, and have lost their firmness. Blood presents no marked 
features except its bright rose-colour, analogous to that which 
we always see in calves killed without being suspended by 
their hind limbs. Cicatrisation of the umbilical cord com¬ 
plete. 
In Case 2 the free margin of the tongue on the left side 
was the seat of an ulceration, which had caused a deeply- 
penetrating lesion of the organ, large enough to contain a 
pigeon’s egg; also the buccal mucous membrane and the 
gum of the left incisors, at the point where they correspond 
to the left anterior extremity of the tongue, in a state of 
mortification. There is, in fact, all along behind the incisors 
a greyish patch, limited in front by the teeth, behind by the 
openings of Wharton’s duct. The buccal mucous mem¬ 
brane mortified throughout the whole of its depth, but offers 
some resistance to the separation or the slough.
