THE POST-MORTEM EXAMINATION OF A RABID OX. 469 
Digestive passages .—The cavities of the mouth and pharynx, 
were thickly lined with very viscid mucus. The bursaj mem¬ 
brane was red at the base of the tongue, and the numerous folli¬ 
cles that open on its surface were surrounded by a distinct red 
areola. The membrane was neither thickened nor softened, and 
the sub-mucous cellular tissue, presented some capillary injection. 
None of the pustules of Marochetti were found. 
The internal membrane of the fourth or true stomach was of 
an ashy-grey colour, and the coats of their natural thickness and 
structure. This membrane presented numerous little spherical 
prominences, of variable size, caused by the presence of some 
gaseous fluid in the sub-mucous cellular tissue: with this ex¬ 
ception, it possessed the character of health. The mucous mem¬ 
brane of the rest of the alimentary canal was healthy, except 
that there were the same prominences as in the fourth stomach ; 
but they were confined to the line at which the small intestines 
were united to the mesentery, and they were collected in spaces 
of ten or twelve inches in length, with intervals of five or six feet. 
The same appearance was observed in the caecum, but it ceased 
at the commencement of the colon. The greater part of these 
prominences were as large as olives. 
The lobules of the pancreas were separated by a gaseous fluid. 
The bladder was contracted in an extraordinary degree, and ex¬ 
hibited on its mucous coat a few arborescent injected vessels. 
Chest .—The cellular tissue separating the .lobes of the lungs 
was the seat of some unusual collections of elastic fluid, grouped 
together in little cystiform cavities, a line in diameter. On 
cutting into the pericardium, more than a pint of reddish serous 
fluid escaped, but the membrane itself exhibited no morbid ap¬ 
pearance. The substance of the heart was pale and easily sepa¬ 
rated. The internal walls of the cavities of the heart were of a 
deep cherry-red colour, but the lining membrane was transparent 
and without colour; while the cellular tissue beneath was highly 
injected. The anterior aorta, as far as its division, and the 
thoracic aorta, contained a firm black clot of blood. 
Brain and spinal chord .—The small vessels beneath the arach¬ 
noid membrane were injected, but the substance both of the ce¬ 
rebrum and cerebellum were unaffected. The corpora striata, 
thelami opticoram, and tubercula quadrigemina presented a dark 
injection, without any softening of substance. 
In the spinal chord beneath the tunica arachnoidea was a 
reddish liquid, like the lees of wine, the third of a line in thick¬ 
ness. All the spinal chord, from the separation of the decussa¬ 
tion of the corpora pyramidalia, displayed in these two substances 
a want of consistence. This softening was more evident poste-
