Cause. On the track, when regiment ordered to another 
State, not possessed of a microscope (wouldn’t know how to use 
it intelligently if owned one), believe that a water insect about 
one-eighth of an inch long and resembling in appearance the 
ordinary screw worm, or a small bot, originates and is propa¬ 
gated in the shallow water around the margin of rainwater 
ponds in Southern Florida. As the animal enters the pond for 
drink or other purposes it is attacked, the insect penetrates the 
dermis and attacks the tissues beneath, with the results already 
mentioned. The insect is known locally as a “leech.” I have 
not had but ten mild cases in twelve hundred horses of the regi¬ 
ment, but have had thirty-two cases in the wagon train of two 
hundred and sixty-one mules ; five cases among the mules died 
from sloughing of hoof, or were shot to end suffering, one horse 
left behind and turned into the veterinary hospital at Tampa, 
I understand. The disease seldom attacks more than one foot 
of an animal. Of course, the general symptoms of the patient 
are those found in cases of severe local inflammations. 
In two cases there was observed complete sloughing of the 
plantar nerve and blood vessels on both sides of theloot and 
immediately above the coronary band. Needless to remark 
these animals went up the flume ; in seventy-five per cent, of the 
cases the disease did not make its appearance until we were on 
the train between Tampa and our new camp at Huntsville, 
Alabama. Horses were never washed in ponds, but some may 
have passed through.

I enclose a report of the death of the stallion Yataghan, by 
Lord Russell, from rupture of the stomach and strangulated 
hernia. I send you this report as the symptoms are so very dif¬ 
ferent from those we generally see. 
On October ii, 1898, about 6.30 p. m., a gentleman called 
at my place, saying Yataghan was sick. I asked him how he 
acted. The symptoms given were that he lies quiet, but occa¬ 
sionally rolls on his back ; not very much pain and not bloated. 
I sent some cannabis indica down, telling him I would be there 
as soon as I could. I got there about 8 o’clock ; found patient 
on his feet and quiet; had given 4 drachms of cannabis indica.
