covery. I have described this case more minutely because it 
was the first case that I was successful in where the power of 
deglutition had passed before I could commence the treatment, 
and by these hope to encourage to a more persistent effort some 
one of my fellow practitioners.

Test Inoculations against Texas Fever [-Report of 
the Commission of the Soc. Centrale de Med. Vet.f —In the No¬ 
vember number of the Review I gave a brief account of the 
investigations of Ligniere in Argentina, in regard to the dread¬ 
ful malady “Tristeza,” or, as it is called here “Texas fevei.” 
In the same article I mentioned the appointment of a commis¬ 
sion, consisting of Messrs. Mollereau, Moussu, Nocard and 
Railliet, to investigate the immunizing effects of the inocula¬ 
tions discovered by Ligniere. The report is as follows : “The 
test inoculations were undertaken in the presence of the mem¬ 
bers of the commission, and for the occasion five cattle were 
employed. Two cows (No. I and No. IV) were inoculated by 
Ligniere, after his arrival from Argentina, with the natural 
disease. Both animals became affected in a mild way, so that 
they could be taken as immunized. Two cows (No. II and 
No. Ill) were submitted, July 5, to the inoculation as recom¬ 
mended by Ligniere, the effect of which was only a slight 
hyperthermia. The fifth animal (fully developed) was only to 
serve as control animal and was not subjected to any treatment. 
O11 July 15 the five animals received subcutaneously injected 
5 cc. each of virulent blood. The two cows, No. I and No. IV, 
which recovered from the slight attack of the disease, did not 
show disturbances of any kind, the appetite remained good and 
the temperature normal; the injection therefore had no effect 
on either animal. The other two cows, No. II and No. Ill, 
behaved in the same manner as No. I and No. IV, the tempera¬ 
ture always being normal, thereby showing the preventive 
inoculations to be an excellent success, as the test animals did 
not show the slightest disturbances. In the remaining animal, 
No. V, nothing was noticed the first five days, the temperature 
fluctuated regularly between 38 and 39°C., the appetite being
