256 QUEENSLAND AGRICULTURAL JOURNAL. [1 Ava., 1901. 
blood, taken on the 22nd, shows a very red serum and a soft clot, whilst the blood of a 
a healthy animal, taken under the same conditions, has a citron-yellow serum, and the 
clot is firmer. In bovine malaria, the hemoglobin is, for a considerable time, scarcely 
held by the corpuscles. 
June 26.—Temp. 38°7 C. Number of corpuscles, 3,557,000. I find a type of 
hematozoa. More multi-nucleated cells. 
June 27.—Temp. 38°9 C. The giant cells diminish visibly in quantity. The 
size of the corpuscles becomes uniform. ‘The serum is of normal colour. 
June 28.—Temp. 38°6 C. The animal is progressing well. 
June 29.—Temp. 38°5 C. Number of corpuscles, 3,999,000. In a red blood 
corpuscle I meet with a hematozoa. The urine still retains a little albumen. 
June 30.—Temp. 38°6 C. 
July 1—Temp. 38°8 C. Number of corpuscles, 4,216,000. The size of the 
corpuscles tends more and more to become uniform; there are several small ones. 
July 2.—Temp. 38°5 C. Number of corpuscles, 4,092,000. A very small 
quantity of albumen in the urine. 
July 6.—Temp. 38°6 C. Number of corpuscles, 5,642,000. All the corpuscles 
have assumed a uniform size. There are no hematozoa. : 
_ July 12.—Temp. 38°7 U. Number of corpuscles, 5,642,000. No albumen in the 
urine. 
July 23—Temp. 38°6 C. Number of corpuscles, 6,618,000. The animal has put 
on as much flesh as before the experiment; its health appears to be excellent. 
August 15.—Temp. 38°7 C. Number of corpuscles, 7,200,000.

(Prare XIV.) 
Cross-bred Durham Bullock.—Age, 2} years. 
On the 24th May, 1899, this animal was injected in the jugular with 20 c.c. of - 
blood of a convalescent beast. 
Up to the 30th no change was observed. Temp. 39° C. 
May 31.—The temperature rises to 40°8 C., but the general condition is normal. 
June 1—Temp. 40°3 C. A slight depression and constipation are observed ; 
still, the animal feeds and ruminates well. The urine is not red. Number of corpuscles 
8,029,000 per m.m.c. Hematozoa very rare. 
June 2.—Temp. 40°2 C. Condition still the same. Number of corpuscles 
6,050,000. The hematozoa are slightly more in evidence. 
June 3.—Temp. 39°4 C. I observe a sensible improvement. The number of 
corpuscles has fallen to 4,900,000. There are few hematozoa; no hemoglobin in the 
urine. The appetite is good. 
June em: 38°8 C. Badly constipated; excreta chocolate-coloured. ‘The 
number of red corpuscles has again slightly diminished: 3,700,000. The urine 
aps alittle albumen; no hemoglobin. ‘Chere are not many hematozoa in the 
blood. 
June 5.—Temp. 39° C. The patient is convalescent. The number of corpuscles 
begins to increase: 3,782,000. Few hematozoa. Giant multi-nucleated cells appear. 
The animal is observed to have become somewhat thin. The appetite remains good, 
the constipation is easier. Still no sign of hemoglobinurea. 
June 10.—Temp. 38°9 C. Number of corpuscles, 4.929,000. No hematozoa. 
June 19.—Temp. 38°7 C. Number of corpuscles, 6,510,000. No sign of giant 
multi-nucleated cells; no hematozoa in the red blood corpuscles. The restoration of 
the blood proceeds very rapidly. 
June 28.—Temp. 38°4.C. Number of corpuscles, 6,355,000. After a long 
search I discovered two corpuscles infested with piriform hematozoa. No multi- 
nucleated cells are observable. The appetite and general condition are good. 
July 1.—Temp. 38°7 C. No hxmotozoa in the corpuscles. Under the micro- 
scope, the blood has the appearance of that of healthy animals; the corpuscles are 
all of the same size. 
This animal is always under observation. Its temperature is taken and blood 
drawn every day. From 1stto 10th the temperature remained normal; yet the animal 
has a very capricious appetite. On the 12th its temp. was 39°9C. I suspect it 
has had a relapse. 
July 13.—'Lemp. 38°5 C. I find many nucleated cells in the blood, a certain 
sign of fresh anemia. In fact, the number of corpuscles now only reaches 3,286,000. 
This anemia must have supervened slowly, for the animal’s urine has never been red. 
I perceive no Pirosuma in the corpuscles.
