sheep received its infection. The cattle may have been in 
fected from the same original source, or possibly there was 
an indirect infection from the dead sheep; but the latter theo- 
ry seems very improbable. The sheep in question developed 
its disease and died in the sheep barn practically surrounded 
by other sheep, and yet we had no other cases among sheep 
at that time and none since. 
PROVISIONAL REPORT ON BACTERIOLOGICAL EXAMINATION 
OF HA:MORRHAGIC SEPTICAEMIA AT STATE EXPERIMENT 
STATION, ST. ANTHONY PARK, JUNE 9th, 1902. 
Specimens were collected from cows No.’s 1, 2, 3 on June 9th and from 
cow No.4 on June 12th, at autopsies conducted by Drs. Reynolds and 
Brimhall. Bacillus bovisepticus (hemorrhagic septicemia) was obtained 
in pure culture from the liver and'spleen of cow No. 4 and was found pres- 
ent also in the lung and meninges of cow No. 1 and in the pharyngeal gland 
and meninges of cow No. 2, though in these latter two animals the bacillus 
was mixed with other organisms such ascolon bacillus. This was prob- 
ably due to the fact that the autopsies were not made until several hours 
after death. 
With the cultures obtained from the meninges of cow No. 1, rabbit No. 
569 was inoculated intravenously, June 13th and died on June 14th (i. e. in 
less than 24 hours). From the rabbit the bacillus was obtained in pure 
culture from the heart’s blood. 
From cow No. 8 this bacillus was not isolated probably owing to the 
very great infection with other microorganisms which had developed after 
the death of the cow. Further rabbit inoculations will be made. In the 
meantime, from three of the sources, the microorganism has been obtained 
and one source, cow No. 1, the organism has been shown to be virulent. 
The strains of bacilli from the other two cows have. been inoculated into 
animals but as yet no results have been obtained.

CASE NOTES. 
Tris.—June 8, 3:00-5:00 p. m. She was slightly stupid, in 
standing position, apparently strong and breathing easily. 
This cow drank naturally and did not show anything unus- 
ual except a slight listlessness. Died at 6:15 p. m. Iris’ 
death was very unexpected until withina few minutes before 
it occurred. See Fig. 7. 
- Vye Cow.—June 8, 11:00 a. m., quiet, apparently com- 
fortable. Could walk fairly well, not supposed to be in any 
serious danger. This cow had a slight convulsion at 9 a. m. 
1-3 p. m. quiet and lying in a comfortable position, died 
very suddenly. : 
June 9, the cow found dead early in the morning in a
