nose. The diarrhœa has continued through the night, and the evacuations now contain mucus and
a small quantity of blood. 5 P.M.—The animal has rallied a little, and the symptoms are less

8 A.M.—The animal is worse, and later in the day the symptoms increased in virulence, and death took
place at 11 P.M. from rinderpest.
Remarks.—Calf.—This animal was about 26 days old when it was brought to the Laboratory at the side of its mother.
The cow was inoculated on the 28th of August 1892 with soiled blood, and the hæmatozoon appeared in its blood on Septem
ber 2nd, and remained present until the evening of the 6th. The calf was allowed to suck its mother three times daily
but during the intervals was secured at some distance from, but in sight of the cow. The milk from each teat of the cow
was subjected to microscopical examination for a considerable period, but no sign of the hæmatozoon was discovered.
Up to the morning of the 9th October, the thirty-eighth day from the appearance of the organism in the blood of the
mother, on microscopical examination of the calf's blood, hæmatozoa were found of some length and very active in their
movements. From that day until the 8th January 1893 no more organisms were observed although careful examination
of the blood was made daily. A point of considerable interest is observed on reference to the charts of the mother and
young one. In the case of the latter the falls in temperature of the mother are faithfully recorded on that of the calf,
and when the temperature of the cow became markedly of an intermittent type, it was recorded, and if anything rather
exaggerated, in the temperature curve of the young one. The calf on the 8th January 1893 was in good condition and
had grown considerably.
This animal was re-inoculated on the 9th February 1893 with 1.0 c.c. of blood containing numerous hæmatozoa
drawn from the jugular vein of Horse No. LXXXIV, immediately after death. The latent period occupied 3 days, and
three paroxysms of 2, 1 and 1 days, with two intermissions of 3 and 123 days, followed respectively. Death from
rinderpest, accidentally contracted, occurred 100 days after the last appearance of the hæmatozoon in the blood.
