colour. Urinary bladder hæmorrhagic. Acute cystitis.
Horse 149.—Gastro-enteritis, mild. Vessels of cerebrum and cerebellum,
highly congested; spinal meningeal vessels—slightly congested in a patchy
manner. Liver, kidneys and spleen congested, the spleen pulp softer than
normal; slight petechiæ on endocardium and on bladder mucosa. Slight
cystitis. Streptococcus melanogenes isolated.
Horse 42.—Slight gastro-enteritis ; congestion of meningeal vessels ex-
tensive, brain and cord ; severe hæmorrhage into pial folds of cerebral cortex,
both sides, and cerebellum and at base of brain ; hæmorrhages throughout the
surface, and brain pulp has a peculiar yellowish colour and somewhat softened ;
gelatinous œdema, cervical and lumbar parts of cord. Kidneys congested;
bladder, much thickening and hæmorrhage ; chronic cystitis. Spleen normal.
Liver, congested.
Horse 513.—Catarrhal inflammation of small intestines ; congestion of
vessels, cerebral cortex and cerebellum; extensive hæmorrhage near the
thalamus ; brain pulp decidedly yellow in colour but not softened ; meningeal
vessels of cord congested, with hæmorrhage in lumbar region, and jelly-like
material between the pia and dura mater. Urinary bladder, hæmorrhagic,
full of blood. Mild cystitis. Spleen—" like an anthrax spleen ". Lymph
glands, dark and hæmorrhagic. Liver, markedly icteric. Blood tarry and
fails to clot. Kidneys, severely hæmorrhagic.
Horse 88.—General gastro-enteritis ; congestion of meningeal vessels,
cerebrum and cerebellum ; spinal, meninges intensely congested with patchy
hæmorrhage of considerable depth. Spleen slightly congested. Urinary
bladder normal. Kidneys and liver congested.
