AUTOPSY.—6 P.M.. 21st October 1891 :
Body much emaciated; hind limbs swollen and œdematous.
On opening the thorax. no fluid was found in the pleural cavities or any signs of adhesions.
Lungs.—The lungs present a pinkish-red colour. without any signs of extravasations on
their surfaces. There is a slight amount of emphysema at the apices of the organs and
several hard nodules are to be felt lying in the tissue of the organ. On section these are
found to be calcareous nodules. easily enucleable.
Heart weighs 6 lbs. The cavity of the pericardium contains about two ounces of an
amber-coloured fluid. perfectly clear in character. There is one extravasation. about the size
of a four-anna piece. lying under the visceral pericardium. covering the right ventricle. and
in proximity with the inter-ventricular groove. The endocardial linings of the right and left
auricles are free from extravasations. But several small ones 1/8th of an inch in diameter and
circular in form. are observed lying under the endocardial lining of the ventricles. The
valves. however. present a healthy appearance.
Liver weighs 12 lbs. 5 ozs. and presents several white patches of thickened capsule on its
anterior surface. the result of old inflammatory changes. On section the organ presents what
appears to be a perfectly healthy structure.
Spleen weighs 2 lbs. 1 oz.. normal in size. firm and dotted over with a few extravasations
of blood.
Kidneys.—Right 1 lb. 7 ozs.; left 1 lb. 71/2 ozs. The capsules strip easily and appear
somewhat pale. but there are no petechias.
Stomach.—Distended with semi-digested food. On section the cuticular portion of the
organ is contracted and wrinkled. presenting a perfectly healthy white appearance. The
villous portion is also contracted and the mucous membrane thereof thrown into rugæ.
There is no sign of congestion or ulceration. and there is a complete absence of parasites.
Small Intestines.—The whole length of the small intestines from the pylorus to the cæcum
presents on its mucous surface a glairy viscid green coloured material like white of egg and
is tinged green from the lucerne grass. There are also three small red patches. each about
the size of a two-anna piece. lying some feet apart but not corresponding with solitary glands
or Peyer's patches and presenting no signs of ulceration. There are no parasites.
Large Intestine and Rectum present a healthy appearance. No parasites.
Remarks.—This was a Grey Australian Gelding. which had been cast from the Royal
Artillery. 16 years old and in good condition. He was kept under observation from March
11th. 1891. until May 4th. and during this period appeared perfectly healthy. It was then
