IVIENINGITIS IN THE HORSE, SUPERVENING ON AN INJURY. BY 1.1 EUT. A. LEA1>I:\C;, A. V.D., MOOI RIVER REMOUNT DEPT., NATAL, SOUTH AFRICA.
THE animal in question had always been of an excitable disposition, and was noticed to have a trick of suddenly running backwards when being ridden, and then could only with difficulty be induced to go forwards again. He great ly resented having his legs handled, and on the day that the accident occurred (December S, 1905), on attempting to pick up his feet, he suddenly reared up and, falling backwards, severely injured his head. He lay stunned for some time and then got up in a dazed, staggering condition, and was taken to the sick lines, but in a very short time became very violent and excited. He continued in this condition from December 8, 1905, to December 14, 1905, when he became paralysed in all four limbs, but s truggled about trying to rise, and severely injured his head in the attempt. He died at 7 a.m. on December 17, 1905. Post·mortem examination showed extreme bruising of the head, particularly about the base of the skull, but there was no fracture. The meninges of the brain and spinal were highly congested, and the brain substance softened , which probably accounted for the peculiar excitable temperament. The softening areas of the brain seemed general, but most noticeable in both central hemispheres and lateral lobes of the cerebellum. The medulla oblongata was a lso affected, so probably the origin of the 10th, I Itl! and 12th nerves were implicated. The base of the brain was somewhat disorganised in removing it from cranium, so I am unable to state what parts of the brain underwent so ftenin g in that position.
