the membrana nictitans; all visible mucous membranes of a pale yellow color; very thirsty.
Feeding fairly well, taking 6 pounds of grain daily and the full allowance of grass. Skin dry
and bound to the ribs. The gait stiff and weak. Œdema of all the legs. Urine and dung not
shown.
In a few minutes after I had made the above notes, just as I was coming away, she showed
symptoms of abdominal pain, became restless, lying down and soon up again, &c, which the
salutri said was a sure sign that she would not live long ; for it was not uncommon for the cases
to have such restlessness off and on in the latter stage, and increasing up to the end. This is
the first time this mare has shown pain.
Evening.—Has had no pain since noon. Pulse 56, respirations 36, temperature lOl3/5. Urine
alkaline, specific gravity 30, there is no trace of albumen, color normal. Dung normal. Fed
up. Examined the blood under microscope, the light not good, found nothing abnormal.
September 20 th—Morning.—Pulse 50, respirations 14, short; temperature 1001/5. Urine,
specific gravity 35, alkaline, free from albumen, sediment normal.
Evening.—Pulse 52, respirations 28, temperature 101 2/5. Urine, specific gravity 26. Dung
normal. Feeding well.
September 21st—Morning.—Pulse 46, respirations 9, not so short as usual; temperature 100.
Urine, specific gravity 35, alkaline, free from albumen. Dung normal.
Evening.—Pulse 35, respirations 30, temperature 102. Urine, specific gravity 34. Fed up.
September 22nd—Morning.—Pulse 56, respirations 12, temperature 1011/2. Urine, specific
gravity 18. Blood examined for the first time in good light by the microscope, parasites found
in great numbers, exceedingly active. I shall give a fuller account of them elsewhere.
Evening.—Pulse 68, respirations 40, temperature 103 2/5. Urine, specific gravity 30. Fed
up during the day.
September 23rd—Morning.—Pulse 58, respirations 14, temperature 101. Urine, specific
gravity 30, has no albumen. Parasites continue active in the blood.
Evening.—Pulse 90, respirations 68, temperature 105. Urine, specific gravity 22. Fed
well during the day.
September 24th— Morning.—Pulse 68, respirations 18, temperature 1022/5. Urine, specific
gravity 20, more high colored, slightly albuminous, alkaline; parasites in blood less active
and fewer.
Evening.—Pulse 64, respirations 48, temperature 102 2/5. Urine, specific gravity 22 ; not so
high colored as in the morning. Fed well.
September 25th—Morning.—Pulse 49, respirations 12, labored; temperature 100. Urine,
specific gravity 28, alkaline, slightly albuminous. Examined a drop of fresh-drawn blood
carefully, found only one parasite, which appeared thicker in the body than what I saw before ;
examined a second drop and found no parasite in it; examined a third drop got from another
fresh cut and found no parasite ; the white corpuscles are much increased in number.
Evening.—Pulse 58, respirations 42, temperature 102. Urine, specific gravity 30. Fed
well during the day.
September 26th—Morning.—Pulse 50, respirations 10, temperature 100. Urine, specific
gravity 30, alkaline, free from albumen.
Evening.—Pulse 66, respirations 45, temperature 102. Urine, specific gravity 22.
September 27th—Morning.—The animal is greatly emaciated, though she feeds so well,
and there is no chance of her recovery. She was therefore destroyed in order to investigate
the disease post mortem. Large quantity of clear serum found in the abdominal cavity and a
slight velvety fluff of lymph upon the parietal peritoneum; no inflammation. Subperitoneal
connective tissue very yellow. Liver impregnated throughout with old calcareous degenerations
of cysticerci larvae from the size of a pea down. The organ was otherwise perfectly healthy
in structure. The stomach and intestines were opened and examined from end to end and
found normal. There were a few subperitoneal petechiae on the free border of the small colon ;
these were examined by the microscope, nothing but a sanguinous exudate was found.
Scrapings and sections of the kidneys were examined by the microscope, nothing abnormal was
found in them. Spleen, heart and lungs were also healthy. Parasites found in the blood, but
not near so many as at first.
Remark.—It is worthy of note in this case that the urine became slightly albumenous with
the disappearance of the parasites from the blood. I found nothing abnormal in the deposit
from the urine, examined carefully for " casts " of the urinary tubules of the kidney. Dung was
always normal. The patient showed no symptom of pain since the morning of the 19th. The
great difference observed between the number of respirations morning and evening I attribute
to the heat of the sun, which came direct upon the horses in the afternoon. The temperature
within a cool bungalow was about 82° every day.
