Experiment XLVIII 
Post- Mortem of Native Bullock* 
Performed immediately after death. Some ten unidentified adult filariae were found in conjunc- 
tival sacs of both eyes. No sores nor discharge from nostrils. On section no oedema of abdominal wall. 
Stomachs enormously distended with food ; small intestines empty. 
Liver. — 2'72 kilogrammes. Substance dark. On upper surface of right lobe was a superficial 
abscess the size of an acorn, which contained a small slough. The abscess was quite localized. Gall 
bladder full of light-green fluid bile. Dotted over surface of mucous membranes were small circular 
injected areas. 
Spleen. — Weight, 793 grammes. Vessels of capsule injected, substance normal. 
Kidneys. — Right, 510.2 grammes; left, 4 5 3 "6 grammes. Appearance, normal. The perirenal 
connective tissue was infiltrated with a yellow gelatinous oedema. Pancreas and suprarenals apparently 
normal. 
Lungs. — Left, upper lobe firmly bound down by old adhesions, substance normal. Right, lower 
and middle lobes deeply injected. On section patchy, recent consolidation present. 
Heart. — Slight amount of straw-coloured fluid present in pericardial sac. Valves, normal. Muscle, 
normal. Some gelatinous oedema along coronary arteries. Fat, abundant. 
Bone marrow of long bones, yellow ; of short bones, dark red. 
Brain. — Slight thickening and injection of the pia mater. 
Lymphatic Glands. — The same appearances were seen as in P.-M. of Experiment XX. 
Once more the most marked pathological changes observed were in the lymphatic glands. Many 
very small, entirely haemorrhagic glands, varying in size from a pea to a bean, occurred in the mesentery. 
All the lymphatic glands were enlarged and oedematous. The medullae of many were of a deep chocolate 
colour, and some of the retroperitoneal group were markedly haemorrhagic.
