Mule I.
Fawn-coloured gelding, aged, height 14-2½ hands, a strong animal in good health and
condition. After a period of observation lasting 28 days, the animal was inoculated on the
muzzle by means of a slight scratch, and a trace of blood containing numerous hæmatozoa,
taken from a guinea pig primarily inoculated from Horse No. CVII, was smeared over
the wound.
The period of incubation lasted 11 days; the disease ran its course in 75 days. The
hæmatozoon was present in the blood for 49, and absent during the intermissions for
26 days.
The following are some of the chief results obtained:—
Water drunk.—During health 13.80 litres were taken daily; the amount rapidly decreased
throughout the rest of the case, being in the latent period 12.23, paroxysms 9.68 and inter-
missions 7.37 litres, respectively. For the whole period, 114 days, it averaged 10.41 litres or
2.3 gallons.
Water in food.—In addition to the above, 4.38 litres (9.64 lbs.) were taken in daily as
moisture in the fodder and grain, equal to a total of 14.8 litres or 3.25 lbs. ingested. The
ratio of the water egested to ingested was in heath 1 : 1.71, it decreased in the latent period
to 1 : 2.07, whilst during the paroxysms the ratio was the same as in health ; but in the
intermissions it rose to 1:1.54, and for the whole period of 114 days it was the same as in
health.
The amount of water ingested during health was as 1:15.29 of the body-weight, whereas
during the last paroxysms, of four days' duration, the ratio was 1: 57.29.
Food.—This consisted of hay, lucerne, gram (for the first nine days), then barley and bran.
The animal weighed at the commencement of the experiment 698.5 lbs. and at death,
114 days later, 442.30 lbs., showing a loss in body-weight of 256.20 lbs., equal to 36.69 per
cent.
The difference between the Nitrogen ingested in the food and egested in the urine,
dung, &c., during the same period amounted to 56.82 per cent. of the total loss, calculated
as proteid matter ; the remaining loss was due to moisture, carbonic acid, &c.
Urine.—The mean daily quantity of urine voided in health was 2,514 c.c., it decreased
slightly during the latent period, but nearly doubled during the paroxysms (4,642 c.c.).
This latter quantity was slightly exceded in the intermissions, the output being 4,683 c.c.
For the whole period it averaged 3,914 c.c.
