Autopsy.—The lesions are identical with those which were observed in the case 
of the last animal, with the exception that the liver is reddish-brown instead of 
yellowish. The articular synovia is russet-coloured. There is found in the cardiac 
muscle and in the kidneys an enormous number of hematozoa, intra-globular or free. 
3.—VIRULENT DISEASE TERMINATING IN RECOVERY. 
(Prare XIII.) 
Bullock aged 2 years of the ordinary breed of the Province of Buenos Ayres (an 
immune district). 
on June 9, 1899, I injected beneath the skin of this animal 10 c.c. of virulent 
bloo 
June 10.—Temp. 38°6 C. I found no hematozoa in the blood. 
June tsar acre: 38° C. After a lengthened examination I finished by discover- 
ing in the jugular blood a corpuscle containing two typical piriform hematozoa. 
June 12.—Temp. 38°7 C. ‘Lhe hematozoa are still scarce, but they are more 
easily detected than on the previous evening. The general condition of the animal is 
excellent. Number of corpuscles, 9,000,000 per m.m.c. 
June 13.—Temp. 40°2 0. Notwithstanding this sudden rise of temperature, and 
the presence of a considerable number of hematozoa in the blood, some of which are 
free, the animal scarcely appears unwell; it feeds as on the previous day. In the 
evening the urine begins to show a reddish colour, and contains some albumen. The 
number of red corpuscles has fallen to 6,572,0U0 per m.m.c. 
June 14.—Temp. 40°8 C. The patient is greatly diarrhawad, and the excreta 
Basen the urine is red. The animal is depressed, eats nothing, and appears to be 
very ill. 
Sees of corpuscles.—Only 1,550,000 per m.m.c.; 10 to 15 per cent. are 
infested with Piroplasma. . 
June 15.—Temp. 39°5 C. The animal continues to be very sick. The muzzle is 
pale; the urine red, contains enormous quantities of albumen. 
Number of corpuscles. —310,000 per m.m.c. 
June 16.—Temp. 38°1 C. The animal appears to be a little better; it is weak, 
eats very little, constipation sets in; the urine becomes rose-tinted; in the evening it 
contains no longer any hemoglobin, but still holds albumen. The number of 
corpuscles is 434,000 per mm.c. The hematozoa are less numerous than on the 
previous evening. 
June 17.—Temp. 38°1 C. The animal is better; ithas a slight appetite. Number 
of red corpuscles, 433,000 per m.m.c. ‘There are few hematozoa. In the blood I finda 
giant multi-nucleated corpuscle. The blood serum is slightly rose-coloured. No 
hem» globin in the urine. L 
June 18.—Temp. 39°5 C. The animal is slowly approaching convalescence. It 
is difficult to detect any hematozoa, whilst on the other hand, the giant multi- 
nucleated corpuscles are very numerous. Number of corpuscles, only 372,000. The 
plood serum is pink; the blood-«lot scarcely dissolves in it. 
June 19.—Temp. 38°7 C. The number of rd corpuscles has risen to 502,000. 
The animal eats well, no longer appears sick, but still remains very weak and ansemic. 
Constipated. 
June 20.—Temp. 38°5 C. Number of corpuscles, 600,625 per m.m.c. The blood 
serum is siill a little pink. The urine contains albumen. I can find no hematozoa, but 
the giant multi-nucleated cells are very numerous and filled with spherical or irregular 
granulations, strongly stained with methyline blue. ‘the granulations are so 
numerous and so minute in a given number of corpuscles, that the latter are stained 
completely blue, and a mere superficial examination would lead to the belief that they 
were white corpuscles. 
June 21.—Temp. 38°6 C. The number of corpuscles has abruptly risen 
to 3,089,000. ‘The giant cells are still numerous. There is a considerable number of 
small red corpuscles. The excreta begin now to assume a normal consistency, but 
still retain the rusty colour. 
June 22.—Temp. 38°70. Number of corpuscles, 3,263,000. The general 
condition of the animal shows visible improvement. ‘There are no Piroplasma in the 
blood ; many small corpuscles and also an equal number of giant multi-nucleated cells 
are perceptible. Serum still pink. 
June 23.—Temp. 38° C. Number of corpuscles, 3,348,000. 
June 24.—Temp. 38°43C. Number of corpuscles, 3,131,000. Giant cells still 
present, but no Piroplasma. 
June 25.—Temp. 38°7 C. Number of corpuscles, 3,627,000. The mucous 
membranes and the muzzle are not so pale. The animal is recovering strength. The
