developed and it was taken into the Infirmary where it remained three days. On the 17th,
as the temperature was 37.2°C, it again was worked, doing 13 miles per diem, until 24th,
when a general eruption of Urticaria broke out: on that date the temperature was 37.2°C.

On admission.—The animal is in fair condition, but looks aged ; there is no fever, but
the conjunctival membranes present large claret-coloured extravasations, especially involving
the membrana nictitans3 in both eyes. The general surface of the skin looks uneven, and
puffed, and on the left side of the neck there are several patches which appear to be the
remnants of an Urticarial eruption which has almost disappeared. There is slight œdema
about the fetlocks which are neither hot nor painful to the touch. Temp, A.M. 38°C. The
pulse is weak and thready—56 beats—and the respirations are 36 per minute. The hæma-
tozoon is absent from the blood; the red corpuscles form healthy rouleaux and the white
are normal as regards number and size. Temp. 1 P.M. 37.7°C.
Urine.—Turbid, yellow, Sp. Gr. 1,018, alkaline, contains no albumen, crystals of
Carbonate and Oxalate of Calcium. Temp. 5 P.M. 38.3°C. P. 44. R.40.
One dose of the double Iodide of Mercury and Potass, gr. ii, was administered in the
evening.
1st November.—The condition of the animal is unchanged except that there appears to
be a slight increase in the amount of oedema of the hind limbs. Temp. A.M. 38°C. P. 44.
R. 20.
The hæmaoozoon is absent from the blood. Temp, 1 P.M. 38.5°C. Urine, turbid,
orange in colour, Sp. Gr, 1,034, acid in re-action and contains a trace of albumen.
Two doses of the medicine were administered during the twenty-four hours. Temp.
5 P.M. 38.2°C. P. 44. R. 20.
2nd.—This morning the animal is bright and moves freely about its loose box. There
is a discharge of mucus from the right nostril. The eruption has not altogether disappeared
from the skin, as a few patches of Urticaria are still visible on the left flank. The petechiæ
are fading from the conjunctivæ. Temp. A.M. 38 . 1°C. P. 44. R. 16. There are a few
hæmatozoa in the blood. Temp. 1 P.M. 38.4°C. Urine, turbid, viscid, orange, Sp, Gr. 1,032,
acid, contains a slight trace of albumen, crystals of Carbonate and Oxalate of Calcium.
Two doses of medicine were administered during the twenty four hours, the latter
containing grs. iv. Temp. 5 P.M. 39.8°C. P. 60. R. 24.
3rd.—This morning a general eruption of Urticaria appeared over the neck, chest, ribs
and flanks, the largest wheals being observed over the ribs and under-surface of the
abdomen. The eruption began to disappear at 10 o'clock and by noon only little was left—
a few patches over the neck and scapular regions. Temp. A.M. 39.8°C. P. 64. R. 20.
There are a few hæmatozoa in the blood. Temp. 1 P.M. 40°C. Urine, turbid, viscid,
yellow in colour, Sp. Gr. 1,040, alkaline, contains no albumen; crystals of Carbonate and
Oxalate of Calcium. Two doses of the medicine were administered during the twenty-four
hours, the last dose being increased to gr. v. Temp. 5 P.M. 39.5°C. P. 48. R. 28.
4th.—An eruption of Urticaria is again well marked this morning over the skin cover-
ing the neck, chest, scapular regions, ribs, hind quarters and extremities, and between the
thighs ; some of the individual patches of the rash are one inch in length by half an inch in
width at their widest part,-and oval in form. The visible mucous membranes are clean and
healthy-looking, and petechiæ are entirely absent from the conjunctiva). The pulse is
regular and only slightly increased in frequency. The appetite is very good. Fæces
normal in character. Temp. A.M. 39.1°C. P. 44. R. 28.
The hæmatozoa are numerous and active in the blood, and many are attached by their
flagellated extremities in groups of two and three. The red corpuscles are massed together
but do not form healthy rouleaux. The white corpuscles are not increased in number.
Temp. 1 P.M. 40.l°C. Urine, turbid, viscid, yellow in colour, Sp. Gr. 1,018, alkaline,
contains no albumen. Two doses of medicine were administered during the twenty-four
hours; the latter was, however, increased to grs. vii of the drug. Temp. 5 P.M 40.5°C
P. 64. R. 28.
5th.—The animal looks fairly well but on examination the visible mucous membranes
present a yellowish, unhealthy appearance, as also the conjunctivæ; the tongue is furred
the skin hot, the pulse full and hard and there is a general fulness of the veins of the body
especially noticeable in the sub-maxillary when the pulse is being felt. The eruption has not
altogether disappeared. One or two patches are still to be observed on the right side of
