7. If, however, the foal is suffered to live, it should be 
separated from pregnant animals before any of the swellings 
exhibit suppuration or sores. 
8. A mare, the dam of a foal suffering from the joint-ail, 
should undergo the same antiseptic treatment as though she 
had aborted, providing she is not doing well. 
9. Mares that have aborted and done well should not be 
allowed to stallion sooner than two or three weeks after the 
accident. 
History of Experiment and Result so far as Ascertained .—A 
few days after arriving at the ranch, June 25th, “ Biddy Mac,” 
a trotting brood mare, gave birth to a foal. This foal, pre¬ 
viously mentioned, was very weak, and died from starvation 
in two days after its birth. A post-mortem examination was 
held, but nothing could be found sufficient to cause death. 
The udder of the dam was then examined, and no milk found. 
Cultures were made from the blood and several of the glands 
of the colt, to see if they might possibly contain any of the 
germs causing the trouble. It is not intended to give the re¬ 
sults in detail, as many of the minute points were only tedious 
and of no practical value to the general public. 
Cultures were made from the diseased foetal membranes 
from “ Biddy Mac,” and inoculation made therefrom. One 
bay mare in foal received the inoculation on June 6th, and on 
the following night she foaled. On June 29th, the foal showed 
signs of joint trouble in right knee, and on July 1st the hock 
joint was as large as a man’s head. Thus, from this experi¬ 
ment almost just begun, we might say, do we produce the 
disease in a colt that when born was apparently in health, 
and that, too, after the inoculation had only been introduced 
a few hours. 
Another mare, a dun, inoculated with a culture from the 
blood of Biddy Mac’s colt on the 20th day of June, gave birth 
to a dead foal. This was an abortion, as evinced by the dis¬ 
eased placenta. Hence we see that from these two inocula¬ 
tions with culture we have produced both the diseases, abor¬ 
tion and joint trouble. The germs causing these two dis¬ 
eases are the same, as shown under the microscope. That
