ECHINOCOCCOSIS OF THE BRAIN, LUNGS, AND LIVER IN A HORSE. 505 



State oil Examination. — The animal was still lying on its off side, and 

 appeared fairly comfortable. The pulse was 50, soft, and of good 

 volume ; respirations 16, temperature ioo|-°. The conjunctiva was of 

 a brick-red tint, and the pupil sensitive to light. 



The animal was turned over and placed in a position to rise, but in 

 spite of some assistance it made no effort to do so. Examination of 

 the back and off hind limb revealed no injury. There was neither pain 

 nor crepitation, and sensation seemed good in both hind limbs. The 

 statement (elicited by close questioning) that the pony had not been 

 exercised for some days, but had been liberally fed, aroused suspicion 

 of haemoglobinuria, although the lumbar muscles did not show the 

 usual stiffness. The suggestion was afterwards negatived by the urine 

 continuing perfectly normal. 



As it was important to raise the patient, and allow it, if able, to 

 stand, this was done, but the animal failed to place any weight on the off 

 hind limb, which seemed para- 

 lysed : while the near, though 

 sustaining weight, could not be 

 moved. The united efforts of 

 five men were required to keep 

 the animal on its legs, and 

 therefore after the bed had been 

 renewed and increased it was 

 again let down. 



Failing any positive evidence 

 to the contrary, and no urine 

 having been found in the blad- 

 der, the case was at this stage 

 treated as azoturia. Stimu- 

 lating applications were made 

 to the loins, and an anodyne 

 draught containing Tr. Opii fl. 

 3ss, Chloral Hydrate Jj, Spt. 



Tereb. fl. jss, and 01. Lini Oss administered, and ordered to be re- 

 peated in four hours. 



By 8 p.m. on the same day (June 3rd) there was no particular 

 improvement, but the urine having been examined the diagnosis of 

 azoturia became untenable. In the meantime, however, the pupils 

 became insensitive to light, and some difficulty was shown both in 

 breathing and swallowing. Cerebral injury was therefore suspected, 

 and a dose of aloes and calomel given to unload the bowels. Cold 

 applications were made to the head, and at a later date a blister was 

 applied. 



At 6 p.m. on June 4th the pony was still unable to rise, and lay 

 with the head and neck fully extended. The pulse was imperceptible 

 either at the submaxillary or radial arteries, and the heart's impulse 

 could not be detected through the chest wall. The respirations were 

 57. The pupil was fully dilated and completely insensitive to light ; 

 the retinal vessels appeared enlarged, and the bright reflection from 

 the tapetum was dulled by what seemed to be a deposit of lympho A
