MYELITIS SPINITIS ACUTE PARAPLEGIA. 499 



hind limb, so that it was with difficulty it was got into the 

 stable. 



At 7.30 P.M. my father found it on three legs, with violent 

 muscular tremblings, evidently in great agony, and shrink- 

 ing from the slightest touch. 



At 9 P.M. my father, Mr Law, and myself, visited the 

 patient, and found paralysis of motion in both hind limbs, 

 though sensation seemed to be retained. The animal could 

 rise on its fore limbs, but only partially on the hind, these 

 being bent, with the pasterns resting on the ground. The 

 respiratory movements of both thoracic and abdominal 

 muscles were normal The hind legs were drawn up again 

 when pulled back by the hand, and were thrown out 

 slightly with the general movements in the frequent 

 struggles of the animal. Pricking the tail with a pin caused 

 its ready movement. The line of the lumbar and sacral 

 spines was regular, and neither they nor the dorsal showed 

 tenderness on being struck. The mare was in violent 

 agony, with the pulse at seventy-two per minute, full, but 

 soft, the skin drenched with perspiration, and the eye 

 abnomally bright, as in colic. The expression of the face 

 was haggard, and the head frequently turned to the flank, 

 as in abdominal pain. 



At 10 P.M. I found her in the same condition, excessively 

 restless, and suffering severely. Gave an anodyne draught, 

 which partially relieved the pain. 



Examination per ano, detected healthy beating of the 

 posterior aorta, and of both the iliacs on each side, and de- 

 cided that no retention of urine existed. 



By applying the ear over the heart near its base, I de- 

 tected a rushing sound replacing the second sound of that 

 organ. An hour later, Dr Arthur Gamgee accompanied Mr 

 Law, and examined the heart carefully with the stethoscope.
