GENERAL LYMPHANGITIS.

took their animals, one hundred and thirty head in all, home 
and fed them on gram and hay, to prepare the same for work 
in the harvest. Hardly three weeks later, each one of these 
farmers had one mule complaining of this mule disease ; that 
one of David Kerr was all gangrened in the head, and killed 
after three or four weeks ; it formed the subject of the post 
mortem examination given above. The mule of James 
Kenealy broke out in a hind leg; I lost sight of him ; the 
third one belonged to W. W. Stone, and received my close 
attention for one month. This mule was three years old and 
fat; broke out on legs and body, having, inside of one week, 
over one hundred abscesses and buttons ; both nasal cavities 
were gangrened, but there never was any oedema in the glot¬ 
tis. This mule was lively, ate well, and had all the time a 
splendid coat; but gradually the disease progressed, and be¬ 
fore the farmer concluded to destroy her I was allowed to 
experiment on her. I inoculated an old mare in three places, 
one on the left costal region, and one on each side of the neck, 
by making a cut about two inches long and pouring the fluid 
extracted from a newly opened abscess of the mule in the 
pocket of these cuts, and closed them up with one stitch. 
Then I coated a small sponge over with the nasal discharge 
of the same mule by holding and turning the sponge around 
in the nostrils, and introduced this same sponge in both nos¬ 
trils of the mare, for a few minutes. At the same time, the 
mare was tied up near the mule, eating out of the same man¬ 
ger and drinking from the same pail. Fourteen days later 
Mr. Stone resolved to kill his mule, and my mare was taken 
out and destroyed. The three wounds where I had intro¬ 
duced the matter taken from the mule, were giving a good 
deal of suppuration of a very healthy character and no swell¬ 
ing, nor cord, nor tumor, could be detected either around 
the three inoculated wounds nor on any part of the body. 
The nasal cavities were clear, and no ganglion swollen. The 
mare was declared sound. 
No sick animal could be found on the premises of either 
one of these three farmers, nor in the pasture. In all certain¬ 
ty these mules were not glandered, unless it be the acute type ;
