ENGLISH REVIEW. 
Median Neurotomy [By IV. B. Nelder]. —This opera¬ 
tion is making its way in the domain of veterinary surgery, and 
continues to give the same satisfactory results in relieving lame¬ 
ness due to diseased conditions of ligamentous and tendinous 
structures, and to bony deposits of the lower parts of the an¬ 
terior extremity. In his article the author records his experi¬ 
ence in six cases where excellent results were obtained. Lame¬ 
ness due to splints, chronic thickening of the suspensory liga¬ 
ment, of the perforans and perforatus tendons, of ringbones and 
sidebones, and also navicular disease, were relieved and the 
animals returned to work, which they have performed evei 
since to the satisfaction of their owners. The lameness had ex¬ 
isted previous to the operation for from three to six months and 
in two of the cases for twelve months. The cases were recorded 
in the Journal of Comparative Pathology. Mr. J. Webb, in the 
Record , reports the case of an aged mare which had been lame - 
for several years, due to ringbone, chronic sprain of the back 
tendons, and an enlarged knee. In all three cases the lameness 
subsided immediately. In one it returned after three months, 
but was relieved by blistering, which permitted the animal to 
work for six months, when it was disposed of. 
Pulmonary Filariasis in a Mule [By H. B. Elliot , M. 
R. C. V. N.].—It is unfortunate that a minute post-mortem ex¬ 
amination could not have been made in this interesting case ; 
but imperfect as this was, the history and the manifestations 
presented, were certainly very uncommon. This mule, aged 
seven years, was laid up on account of lameness in the rear hind 
leg ; she had been more or less tender in that extremity on several 
occasions. From general examination a diagnosis of hip lame¬ 
ness was made, and, the animal improving, she was returned to 
work. For several months the mule was able to perform her 
duties, although never entirely free from lameness; she was 
considered u a good working mule.” One day she re-entered the 
hospital for a swelling extending from the point of the near 
elbow to the adjacent thoracic region, attended with consider¬ 
able lameness of the near leg. This subsided under anodyne 
treatment. Some two weeks later she was found down in her
