Dull, very hot skin. 
27 | Sam: -..- 107 Skin very hot, hips stained with feces. Defecations semi-fiuid, 
| dark greenish, with clayey aspect, and fetid. Pulse 160 per 
minute. Breathing 28 per- minute; deep, rather labored; 
wheezing inspiration, terminated by a snore. Can scarcely be 
' roused, and crouches in the litter at once when released. 
28} 10a.m..--| 104.5 Scouring. Feces offensive. Lies constantly on belly. When 
lifted hangs helpless with no attempt at struggling. Discolor- 
ation is very marked on ears, snout, belly, and thighs. 
29 | 9.30a.m-.| 102.75 Ran from bed to avoid being caught, but hangs helpless in hands 
when lifted. Feces very soft; fetid. Skin more deeply col- 
ored than before, but cool. 
30 | 2 p.m..... 99.75 Very sick; stupid; stands constantly with fore limbs drawn 
back and hind advanced, so that all four feet meet. Flanks 
hollow. Skin on discolorations very deep purple, almost black 
onrump. Bowels loose. Fetid. 
31} 9a, m..--- 94.5 Lies in stupor, with limbs and body jerking every instant. 
: Breathing slow, sighing, rattling. Feces and urine discharged 
involuntarily, and have soaked the left (lower) thigh, which, 
in consequence, shows a much brighter red than the other 
parts of the body. The general surface, excepting some white 
patches inside the arms and thighs, was of a dark purple, al- 
most black on the ears, snout, median line of the abdomen, 
rump, and hocks. Killed by bleeding.

Post-mortem examination.—Blood: Seanty; that from axillary vein is neutral or 
slightly alkaline. Red globules deeply crenated and shrunken very disproportion- 
ately to the white globules, which are large and rounded, but appear deficient in 
numbers : 1:: 80. 
Skin: Section of the blue skin of the ear shows cutis, cuticle, and bristle follicles 
deeply congested, most of the capillaries being blocked by coagulated blood, and 
microscopic extravasations appearing at short intervals. The red globules in this 
part are full, rounded, and of Ae usual size. 
Digestive organs: Tongue has a series of white sloughs along its tip and right margin, 
resembling those of the intestines, being yellowish-white, laminated, non-vascular, 
and with very slight congestion and redness around them. Microscopically theso 
sloughs are composed of epithelial cells with much granular matter. In one a central 
red spot presents stagnation and coagula in the capillaries and microscopic extravasa- 
tions. It is manifest these form in the same manner with the sloughs in the intestines. 
Circumscribed spots of the mucous membrane become the seat of congestion, resulting 
in coagulation of the blood in the capillaries and exudation and extravasation alike 
into the epithelial and sub-epithelial layers, leading to thickening and induration of 
the deeper strata, and death of the more superficial ones. 
Soft palate: The buccal or lower surface bears a similar slough, while many of its 
follicles are red, swollen, and filled with a yellowish-white (cheesy?) matter. 
Throat: The laryngeal surface of the epiglottis is congested, the redness being in- 
effaceable by pressure. The mucous membrane on the back of the right arytenoid 
cartilage bears a four-lobed warty looking excrescence like a small pin’s head, which, 
under the microscope, discloses only round granular cells and free granules. 
Abdomen, Stomach: This contains a few ounces of half-digested food. This, together 
with the lower portion of the gullet, is of a deep yellow hue, apparently from regur- 
_ gitated bile. No marked congestion of the mucous membrane. 
Small intestine: Shows circwmscribed spots and patches of congestion and small 
petechia, but no erosions.
