    Uterus and appendages, per incuriam, not examined. Large abdominal veins full of dark, fluid blood ; little or no blood in aorta. Brain and its membranes—skull and scalp healtby; no niai'ked congestion nor venous engorgement in any; ventricles moist, but contain no appreciable amount of serum; choroid plexus congested; cerebral substance firm, normal, no increase of its puncta vasculosa ;'' the internal ganglia and the cere- bellum normal. [Brain examined 60 hours after rest of body.] The weight of the body after evisceration is 4 lb. Tlie following were the post-mortem appearances noted, on the 28th November, in dog No. 3. Exhales a most nauseous odour ; rigor mortis well marked ; eye-lids half closed ; corneee hazy ; muzzle firmly closed ; stout muscular animal; muscles well developed, dull in colour, very dry; temporal miiscles, when removed, appear as rigid as dried ham, and can readily be cut into thin slices; sub- cutaneous cellular tissue, and fat and cellular tissue of thorax and abdomen also very dry. On opening thorax, viscera are dry and collapsed; cartilages of the ribs ossified. Lungs weigh 6 oz.; slightly overlap pericardium; of a light reddish colour, covered with bluish-black punctuate mottling ; crepitant throughout; congested to a slight degree posterior- ly ; on being cut into dark blood escapes from numerous points ; otherwise healthy. Bronchi normal; no congestion nor increase of mucus. Trachea pale ; quite healthy. Pericardium merely moistened with serum; no ecchymosis. Heart weighs 3 J oz.; normal in all its walls, cavities, orifices, and valves. Both ventricles contain dark, semi-clotted, but comparatively fluid blood, which also fills the auricles and great vessels. No coagula of any kind. Left ventricle firmly contracted; right very flaccid ; muscular substance firm, dull in tint; heart appears dilated, especially at its base, probably on account of the quantity of blood contained in the ventricles, no ecchymosis posteriorly ; muscular substance normal; aorta quite healthy. (Esophagus healthy; mucous membrane pale ; plicte distinct, covered with very thick viscid but normal mucus. On opening abdomen, viscera very dry and collapsed; mesentery resembles a diaphanous membrane like tissue- paper beautifully ornamented by arborescent lacteals and veins, the latter gorged with dark blood ; the omentum has the appearance of a lax network of the most delicate silky fibres, covering the intestines, and containing in its areolae C
