July 18.—Temp. 38°7 C. Number of corpuscles 4,310,000. The animal is 
progressing well. 
July 23.—Temp. 38°4C. Number of red corpuscles, 5,600,000. 
July 30.—Temp. 38°7 C. Hed corpuscles, 6,700,000. One corpuscle contained 
two hematazoa. 
August 4.—Temp. 38°3 C. Red corpuscles, 7,150,000. There are still a very few 
red, multi-nucleated corpuscles. This bullock is doing very well. 
ATYPIC FORMS.

(Pirate XV.) 
Bullock of no particular breed.—Age, 3 years. 
On the 26th October, 1899, I injected into the jugular of this bullock } c.c. 
of emulsion taken from a kidney from an animal which had died a natural death. 
Temperature 39° C. 
October 27.—Temp. 39°3 C. Red corpuscles, 8,1000,000 per m.m.c. 
ri 28.—Temp. 39°2 C. ; 
»  29.—Temp. 39°2 C. - 
»  80.—Temp. 39°5 C. So far, the subject has remained in health, the 
examination of the blood showing nothing abnormal. 
October 31.—Temp. 40°4 C. ‘The general condition is good, but the appetite 
diminishes. 
November 1.—Temp. 40°9 C. The animal appears sad and depressed; has 
scarcely any appetite. There is no hemoglobin in the urine, nor do 1 observe any 
hematozoa in the blood. 
November 2.—Temp. 41°92 C. The animal no longer eats. It visibly loses flesh, 
and yet the blood shows no trace of hematozoa. There is no hemoglobin in the 
urine. Number of corpuscles, 8,050,000. 
November 3.—Temp. 41°1 C. It is still impossible to find a single hamatozoa in 
the corpuscles. The colour of the urine is normal. 
November 4.—Temp. 41° C. The animal takes no food. It is exceedingly 
emaciated, its flanks are very hollow. For hours it remains standing, the head sunk, 
the eyes haggard, and foams at the mouth. Towards 5 p.m. it is seized with a violent 
trembling, which convulse it at shorter intervals. Shortly afterwards there occurs an 
emission of urine, slightly reddish, owing to the presence of hemoglobin, and containing 
a large quantity of albumen. When the animal is forcibly compelled to move, the 
hindquarters waver, and the carriage of the head presents that special stiffness 
alluded to in the article on symptoms. The excreta are liquid, yellowish at first, then 
of a rusty colour; 75 respirations and 120 pulsations per minute may be noted.. The 
red corpuscles number 7,100,000 per m.m.c. in the morning, and in the red corpuscles it 
is difficult to find a few scattered intra-corpuscular hematozoa of remarkably small size. 
November 5.—Temp. 40°9 C. The number of corpuscles has fallen to 4,464,000 ; 
the urine is bright red. The animalappears to be at the point of death; ever since 
the morning it has struck its head against the wall, struggles to breathe, and appears 
totally indifferent to its surroundings. More infested corpuscles are found in the 
blood than could be detected on the previous night, but the number is still restricted. 
At 4 p.m. the animal died. 
Autopsy.-The muscles are normal. The mucous membrane of the digestive 
canal is slightly reddened; towards the end of the cecum there are blood. clots. 
On the peritoneum there are some petechiw. The intestinal lymphatics and sub- 
lumbar regions are somewhat hypertrophied, infiltrated, and hemorrhagic. The 
spleen is firm, moderately hypertrophied with a black pulp. The liver is of a violet- 
brown colour, the bile clotted and dark, less abundant than usual. The kidneys are 
covered with an enormous hemorrhagic edema; they are dark-brown, friable, and 
much congested. The urine is bright-red. The pancreas is very much reddened. 
Nothing abnormal is noticed in the lungs. 
The heart has only a few hemorrhagic spots on the surface ; on the other hand, 
there are many on the left endocardium. The colour of the cardiac muscle is almost 
normal. The blood coagulates and reddens quickly when in contact with the air; at 
first sight it is not clear, as we have seen in other virulent cases. A large number of 
round hematozoa are found in the kidneys examined immediately after death, and 
many begin to form spores. Elsewhere, that: is to say, in-the cardiac muscle, the 
spleen, the liver, the pancreas, the blood, there are few hwmatozoa; there are still 
fewer in the marrow, in the thyroid body, and in the lymphatic glands. All the 
hematozoa found were rounded in form, although the examination was made imme- 
diately after death. 
Jt will thus be seen that the pear shape is not always found in the carcass.
