FATAL PNEUMOMYCOSIS IN THE HORSE. 649 
As both symptoms and lesions pointed to an infective 
agency, specimens of the exudate, blood and congested lung 
were taken in sterilized jars to the bacteriological laboratory. 
In these Dr. Moore found and recognized the same microbe 
which had been, present in the Monroe Co. cases, and with his 
cultures the following experiments were conducted. 
Experiment No. i. 
A worn-out horse in otherwise fair health was injected in 
the left lung with io c.c. of culture from the microbe from 
the Forest Home mare. Six hours later the injected animal 
was dull and stupid, with a temperature of 106, and a yellowish- 
red tinge of the conjunctiva. There was some acceleration of 
breathing and pulse, and anorexia, but by the following morning 
the temperature had fallen to ioo, the pulse and breathing were 
nearly normal and appetite was restored. There was slight cre¬ 
pitus in the seat of inoculation, with tenderness on percussion. 
The animal was kept for a number of days, but no further de¬ 
cided febrile reaction took place. When killed the chief lesion 
found was a thickening of the pleura io inches in diameter and 
a large pulmonary nodule with surrounding consolidation of the 
left lung, in the seat of the inoculation. In this exudate Dr. 
Moore found, as had been expected, the now familiar microbe of 
the Monroe Co. cases and the Forest Home mare. 
Experiment No. 2. 
June 6, a small white mare, which had suffered from detach¬ 
ment of the left hind hoof and had nearly completed the growth 
of a new one, was at 10 A. M. injected in the left jugular vein 
with 10 c.c. of a culture from the lung of the Forest Home 
mare. At 3 p. m. the temperature was 107.8, respiration 52, 
pulse 58 ; she was careless of food, perspired under the head- 
stall, and had dark red conjunctiva and pituitary membrane. 
The temperature of the day was 90 with a high dewpoint and a 
fresh northwest wind. June 7, temperature 102.3, respiration 
and circulation quiet, almost normal, and fed well. Tempera¬ 
ture of air 89. June 8, 5 p. M., temperature 101, respiration 26, 
pulse 36. Feeding well.
