Hæmatozoa few in the blood. Temp. P.M.
1st March.—Death.
AUTOPSY.—Body
extremely emaciated.
Lungs are very large, occupying the whole of the pleural cavities, and, on opening the
chest-wall, at once bulge out through the opening. The apices are the seat of well marked
emphysema; whilst the other parts do not show the change so distinctly. The middle
lobe on the right side is of a dark-red colour and consolidated.
Heart is distended with dark-coloured clots ; but there are no petechiæ in its cavities.
Liver.—Large.
On section, appears healthy.
Spleen is enlarged to three times the normal size; but there are no petechiæ on the
capsule. On section, the tissue is firm and looks healthy.
Stomach. — There is some congestion near the pyloric extremity, but no ulceration.
Kidneys.—There are a few petechiæ on the surface of the organs; but on section, they
are not found to involve the structures below.
Bladder.—Healthy.
Remarks.—This animal, when inoculated on November 24th, 1890, with blood containing
numerous hæmatozoa, was eight weeks advanced in pregnancy.
On the 30th or 6 days
later, she had three young ones, one born dead. The blood of the mother and that of the
young ones was free from hæmatozoa. On December 1st, the mother's blood contained
hæmatozoa and continued to do so off and on until her death on March 1st, 1891. The
young ones were kept with their mother and were suckled by her for 67 days subsequent to their
birth. On the 16th December, No. I young one presented a few hæmatozoa in its blood,
but on this day only. On February 4th, it was decided to test whether any protection had
been acquired in utero, or at a later date during the period of suckling. Consequently the
young ones were subcutaneously inoculated in the Inguinal Region with .2 c. c. of blood,
containing numerous hæmatozoa taken from Horse No. XI.
No. I presented hæmatozoa in the blood on the 10th February 1891, and these con-
tinued to be present with only 6 days intermission until June 2nd, the date of death, during
a period of 113 days.
No. II presented hæmatozoa in the blood on the 10th February 1891, and these con-
tinued to be present, with 28 days intermission, until July 3rd, 1891, the date of death,
during a period of 144 days.
The points of interest in these cases are : —
(i). That hæmatozoa should have been present for a period of one day only in the
general circulation of the young Guinea-pig No. I, and the probability is that they gained
