288 Report on an Inquiry into the Nature, Causes, and 
kept sealed up in the incubator for a week. The characters of 
the organisms found in the fluid at the time of inoculation arc 
seen in the annexed drawing. There were, in fact, hardly any 
rods, only spores in various stages of subdivision.

I. and II. drawn with No. 10 imm. Hartnack, No. 3 oc. 1. Stages of division in spore?. 2. Sar- 
cina-\ilie groups of 4 sponiles. II. Rows of spores, some in process of division. III. With higher 
power — spores dividing and divided. 
No symptoms whatever were observed, beyond a slight 
lowering of temperature, as seen in the list of temperatures. 
(The normal temperature of the sheep averages 103° Fahr.) 
The animal fed well, and did not appear to suffer in any way, 
until the evening of the fifth day (96 hours after inoculation), 
when the temperature was 107°. No special symptoms, how- 
ever, were observed. Next morning the sheep was found dead. 
Examination of the hody about ttcelve hours after death. — Well- 
marked rigor mortis. No trace of decomposition. No local 
swelling observed. Skin generally free from exudation or 
ecchymosis. 
Pleurae healthy. Lungs pretty fully distended. Some small 
patches of collapse in upper part of right lung. Throughout the 
whole of both lungs, both on the surface and on section, are very 
abundant dark red spots, which have the appearance of uniformly 
disseminated ecchymoses. They are of nearly uniform size, 
about that of a mustard-seed. There is no appearance of 
pneumonic consolidation around or between them. Bronchi 
and trachea contain frothy blood-stained mucus ; mucous mem- 
brane generally appears somewhat injected. 
Pericardium healthy. Heart : ventricles normally contracted. 
Some small ecchymoses around the base of the left ventricle, in 
the subserous tissue. Endocardium somewhat deeply blood- 
stained. Ecchymoses in the muscular wall of the left ventricle, 
especially in and around the musculi papillares. Valves 
healthy. Blood in the heart imperfectly coagulated.
