APPENDIX F.
SURRA.
Case 6.—Experimental—by drinking affected blood.
Grey Mare, aged 17, Regimental No. 1867, of the 1st Punjab Cavalry.
September 29th, 1880—Evening.—The disease surra having been transmitted by subcu-
taneous inoculation, as shown in appendix D, case 4, and appendix E, case 5, I was anxious to
know whether it could be transmitted also by drinking the blood containing the surra parasite.
Accordingly, Colonel McLean, Commanding 1st Punjab Cavalry, was good enough to place this
and another mare (case 7) at my disposal for the experiment. This mare is one of those to be
cast soon for being old and worn out, but is in good health. Blood examined and found free
from parasites. The mucous membranes have none of the color peculiar in surra. Pulse 38
and temperature lOO 3/5 just before the experiment was made. This mare marched in with the
regiment from Kabul a few days ago ; she has not been exposed to the local influences which
are supposed to induce the disease surra in this district, and is so much the better for a test
experiment. Twenty-four ounces of blood was drawn from the jugular vein of case 4, and without
any delay it was poured down the throat of this mare (fasting) by a horn. In taking it she
coughed a great deal; some of it she spluttered back through her nose. I think about
4 ounces of blood was lost and full twenty ounces went into the stomach.
September 30th—Morning.—Pulse 36, temperature 98 4/5. The blood was examined by
microscope and found normal.
October 1st—Morning—-Pulse 39, temperature 100.
October 2nd—Morning.—Pulse 39, temperature 101 1/5.
October 3rd—Morning.—Pulse 48, temperature 100 4/5.
October 4th—Morning.—Pulse 40, temperature 99 4/5. The eyes becoming suffused. Blood
examined, no parasite found. Has continued to feed well.
October 5th—Morning.—Pulse 44, temperature 102 1/5.
October 6th—Morning.—Pulse 56, temperature 103 2/5. Visible mucous membranes very
yellow. Slight oedema of the legs. Blood examined, parasites found swarming and very active,
but many of them are much more slender and transparent than they are usually seen in
October 7th—Morning.—Pulse 64, temperature 103 1/5. Considerable oedema in all the legs.
Petechiae on the membrana nictitans and vagina very marked. Gait is weak and stiff; in short
she has all the characteristic symptoms of surra well developed.
I was not able to continue my observations of this case.
