    Notes on Cases. Case I. Macacus Rhesus ^. Nov. 18th, 1891. Double section of cord. 11 a.in. Temp. 101°-7F. lp.m. Temp. 940,4 F. Reflexes absent. Nov. 19tli. Takes solid food. Legs flushed and hot. Nov. 21st. Temp. 101o,8F. Tremors of legs. Tendon reflexes absent. Legs still warm. Nov. 23rd. Tremors gone. Limbs cooler. May 16th, 1892. Killed by chloroform. Tendon reflexes had not returned. Lesions found to be at level of 12th thoracic and 3rd lumbar nerve-roots respectively. Case II. M. Rhesus £. Dec. 22nd, 1892. Operation as above. No apparent shock. Dec. 25th. Animal quite well. Jan. 7th, 1893. Knee-jerk has returned. Jan. 18th. Killed by chloroform. Knee-jerks were somewhat exaggerated. Lesions between 9th and 10th thoracic and 12th thoracic and 1st lumbar nerve-roots. Case III. M. Rhesus $. Sept. 22nd, 1893. Double complete division of cord and of posterior roots going to isolated portion on R. side. No apparent shock. Sept. 26th. Knee-jerks present. Reflexes from toes also obtained. Oct. 2nd. Monkey found dead in cage. No suppuration anywhere. One posterior root going to isolated piece on R. side had not been divided. The lesion in each case isolated a piece of cord about two segments long in the lower thoracic region. In monkey I. the knee-jerk never returned: in monkey II. it reappeared after 16 days: in monkey III. already in four days which is, I believe, the shortest recorded interval. Case IV. Cat. May 30th, 1893. Longitudinal division of cord, in lumbar region. May 31st. Both knee-jerks present. June 1st. Can jump up 4 feet (into cage). June 20th. Killed by chloroform. Lesion is between 5th—6th lumbar nerve-roots. Case V. Cat. July 26th, 1893. Longitudinal division in knee-jerk region. Aug. 16th. Killed. Lesion about level of the 6th lumbar nerve-root. O
