VII.— VARIOUS DISEASES. 



PARASITIC ANEMIA (IXODES). 



196. A nine-year-old setter dog, entered hospital November 24th, 

 1894. For several months this dog had been covered with ticks. 

 More than 300 could be counted, fixed principally to the ears, the 

 right side of the head, the left shoulder, the chest, and the dorso- 

 lumbar region. The animal was thin and very feeble, showed slight 

 ptyalism, and its mucous membranes were pale. Appetite was good. 

 Temperature 37*8° C. 



The ticks fixed to the ears and left shoulder were touched with oil 

 of turpentine, and those in the other regions with benzine. At the 

 end of an hour some of the larger which had been touched with 

 benzine began to loosen their hold. An hour later the majority were 

 only attached by the rostrum, and their bodies were blackish ; they 

 were then easily removed with forceps. The large ticks touched with 

 oil of turpentine became detached more slowl3^ The smaller had all 

 preserved their colour. At the end of four hours all the parasites, 

 whether touched with benzine or with turpentine, remained fixed to 

 the skin only by the end of the rostrum. 



The patient showed uneasiness and partial paresis of the hind 

 quarters, resulting from absorption of a certain quantity of the agents 

 employed. It was washed, dried, and rubbed, and given a few 

 spoonfuls of strong coffee and milk containing bicarbonate of soda. 



Some ticks which survived the action of the benzine and turpen- 

 tine were touched with pure carbolic acid. At the end of ten minutes 

 they were easily removed. It is interesting to note that the larger 

 ticks appeared less resistent than the small. 



ECHINOCOCCOSIS OF THE BRAIN, LUNGS, AND LIVER IN A HORSE. 



197. A fifteen-year-old blue roan pony, first seen at 5.30 a.m. on 

 June 3rd, 1895. 



History. — Was thought to have sustained some injury to its hind 

 quarters, and was unable to rise. 



On the previous evening it had been a little restless, and seemed 

 rather uncertain on its hind legs, but becoming quieter after the 

 administration of some simple colic medicine it was left for the night. 

 Early next morning the coachman found the pony lying on its off side, 

 sweating a good deal, and unable to rise. It had been lifted by sheer 

 strength, but could not stand.
