NEUROMA — TUMOR OF A NEKVE. 



Neuroma may be from enlargementof the end of a divided nerve, or da© 

 to fibrous degeneration of a nerve which has been bruised or wounded. 

 Its most frequent occurrence is found after the operation of neurotomy 

 for foot lameness, and it may appear only after the lapse of months, 

 or even years. Neuroma usually develop within the sheath of the nerve 

 with or without implicating the nerve fibers. They are oval, running 

 lengthwise with the direction of the nerve. 



Symptoms. — Pain of the atfected limb or part is manifested, more es- 

 pecially after resting awhile, and when pressure is made upon the 

 tumor it causes extreme suffering. 



Trentment — Excision of the tumor, including part of the nerve above 

 and below, and then treat it like any other simple wound. 



INJURY TO NERVES. 



These may consist in wounding, bruising, laceration, stretching, com- 

 pression, etc. The symptoms which are produced will depend upoa 

 the extent, seat, and character of the injury. Recovery may quickly 

 take place, or it may lead to neuritis, neuroma, or spinal or cerebral irri- 

 tation, which may result in tetanus, paralysis, and other serious de- 

 rangements. In all diseases, whether produced by some form of ex- 

 ternal violence or intrinsic causes, the nerves are necessarily involved, 

 and sometimes it is to a primary injurj^ of them that the principal fault 

 in movement or change of nutrition of a part is due. It is often diffi- 

 cult or impossible to discover that an injury to a nerve has been in- 

 flicted, but whenever this is possible it may enable us to remedy that 

 which otherwise would result in permanent evil. Treatment should 

 consist in relieving compression, in hot fomentations, the api)licatiott 

 of anodyne liniments, excision of the injured part, and rest. 



CEREBROSPINAL MENINGITIS. 



This may occur sporadically as an encephalitis, with implications of 

 the spinal cord and its meninges. Usually, however, it appears as aB 

 enzooty in a stable, city, or farming district, not infrequently extend- 

 ing long distances in certain well-defined lines, along rivers, valleys, 

 or along ridges and mountains. For this reason the enzootic cerebro- 

 spinal meningitis has been attributed by some veterinarians to atmos- 

 pheric influences. The first written history we have of this disease was 

 published about thirty years ago by Dr. Isaiah Michener, of Carners- 

 villo. Pa., in a pamphlet entitled " Paralysis of the Par-Vagum." Sev- 

 eral years later Prof. A. Large, of Brooklyn, IST. Y., gave it the name of 

 " cerebro-spinal meningitis " on account of its similarity to that disease 

 in the human family. Dr. J. C. Michener, of Colmar, Pa., in 1882, 

 suggested the name of " Fungosus Toxicum Paralyticus," in view of 

 the exciting cause being found in foods undergoing fermentation. la
