red stripes entering the substance. In the region or the third dorsal segment, at the 
base of the right posterior horns, were four haemorrhages, the largest being about 
two mm. in diameter, and extending through two segments of the grey substance. 
The structure of the cord in the region of the haemorrhages appeared obliterated. 
Thorax. — Diaphragm reached to the level of the fifth rib on each side. Both lungs 
were adherent to the diaphragm, but were free elsewhere ; parietal pleura normal. 
Right Lung. — Pleura of the upper lobe normal ; that of the lower lobe showed 
dark blood coloured patches. The tissue of upper and middle lobes normal ; the 
lower lobe was congested and of a bright red colour. 
Left Lung. — Under the pleura were numerous small haemorrhages. The lung 
tissue contained patches of congestion. The mucous membrane of the trachea was 
pale and covered with a small amount of clear viscid mucus. The thyroid gland 
normal. The nasal cavity and the sinuses in connection with it, as well as the 
tympanum, appeared normal. The pericardium contained a few c.c. of yellow tinged 
clear fluid. 
Heart. — Size normal ; substance very pale and flabby. The chambers contained 
dark fluid blood and clots. The endocardium, the valves, and the intima of the aorta 
appeared normal. 
Abdomen. — The cavity contained about two hundred and fifty c.c. of a light 
straw-coloured fluid. 
Liver. — Of normal size ; its capsule here and there slightly thickened ; the 
parenchyma pale and friable. 
The Gall Bladder. — Filled with thick, fluid, greenish bile. 
The Spleen.- -Enlarged (20 x 10 x 6 cm.), the capsule very thick and partially 
adherent to the parietal peritoneum ; the pulp very dark purple-red and slightly 
diffluent ; on section, enlarged malpighian bodies could be seen in some parts, whilst 
in others no structure could be made out in the dark purplish mass. 
The Kidneys. — Were of normal size, capsules stripped easily. Externally they 
retained the deep embryonic furrowings ; the cortex presented an appearance of fatty 
striation, otherwise they were normal. 
The Bladder. — Contained nearly half a litre of cloudy urine. The mucous 
membrane was pale. The genital organs showed no changes. The suprarenals were

Stomach and Intestines. — The mucous membrane of the stomach was pale, that of 
the small intestine somewhat congested ; the large intestine being normal. The 
stomach contained a little mucus ; the small intestine was partially filled with 
yellowish-brown chyme, and here and there in the recesses of its folds a few anchylos- 
tomes were found.
