yellowish-brown color. Under the microscope this color is found due partly to the
advanced fatty degeneration of the cells, partly to the yellowish masses of pigment
within the cells.
Bile so thick from admixture of amorphous solids that it scarcely flows from the
incised bladder.
The fatty tissue around both kidneys, especially the left, in a condition of sangui-
nolent oedema. More or less congestion of the entire parenchyma. Minute petechime
in cortical substance. In sections of fresh tissue the capillaries are seen filled with
dense masses of blood corpuscles, in some of which the parasites may be distinguished.
Urine pale, free from hemoglobin. Specific gravity 1015. Neutral. Albumen pres-
ent in small quantity.
In stained preparations of kidney, liver, and spleen a small number of red corpus-
cles are found invaded by large paired parasites.
The digestive tract normal with following exceptions: Contents of manifolds
somewhat dry. On mucosa of fourth stomach a few slightly depressed ecchymoses.
In duodenum Dochrius present. In the ileum worm-nodules of various sizes under
mucosa. Very little dry feces in large intestine. Mucosa shows occasional ecchy-
moses. (For the temperature record, consult pp. 272 and 277.)
No. 52 (satire).-Bull calf of No. 51, aged 4 months. On June 27, 1889, placed in
field II (North Carolina cattle without ticks) with No. 51. No result up to Septem-
ber 14. On this day North Carolina cattle with ticks were put in field II, in which
No. 52 remained.
October 29-November 11.-Calf during this period very sick, as manifested by
marked emaciation, weakness, and loss of appetite.
November 7.-Blood contains 2,219,000 corpuscles in a cubic millimeter. There is
considerable variation in their size, some having a diameter of 9 ,p. When stained,
a small number (perhaps 1 to 2 per cent) are observed with the peripheral coccus-like
bodies.
November 11.-After this date slow improvement. Unthrifty and stunted condi-
tion of calf through the winter. (For the temperature record, see p. 272.)
To. 53 (native).-Heifer, 18 months old, raised on the station. Placed in field II
(North Carolina cattle without ticks) June 27, 1889.
September 6.-There being no result up to date, the animal was transferred to
field I (North Carolina cattle with ticks).
October 4.-Has been losing flesh during the past week and is now very weak and
thin. Can not walk without staggering. Blood examined and found quite thin.
Only 2,766,666 corpuscles in a cubic millimeter. In stained coverglass preparations
the red corpuscles vary in size; some are quite large and show a large number of
stained points on the disc, as if dusted over with granules of coloring matter.
October 10.-Slight improvement in the general condition since October 4. Blood
examined to day. Only one intraglobular coccus-form seen, while there are a small
number of the punctate corpuscles, described above, present. In one cubic milli-
meter of blood 2, 626,666 corpuscles present.
November 7.-Blood examined. About 3,560,000 corpuscles in one cubic millimeter.
In preparations stained in alkaline methylene blue there are in perhaps 10 per cent
of the red corpuscles barely visible coccus-like bodies, quite invariably on the periph-
ery of the corpuscle, often on the very edge, one in each corpuscle.
November 11.-General condition has remained unchanged during the past month.
Still weak and thin. Gives birth to a 6i months' foetus.
December 2.-Blood examined, but no abnormal forms detected. In one cubic nilli-
meter about 3,080,000 red corpuscles. Slight general improvement. Animal still
very thin. Appetite has returned.
April 1, 1890.-Improvement slow during the winter. Now in fairly good condition,
July 4.-Now in fine condition. Exposed in field VI (North Carolina cattle with
ticks).
