Owing to the propensity to lick and the danger of absorption, poisonous agents are virtually proscribed. Yet Möller advises cantharides, croton oil, mercuric iodide, and oil of mustard, and Trasbot restricts the choice to tartar emetic one part to sixteen parts of lard. This the latter rubs softly along the spine for several minutes. If the dog is closely watched or muzzled this or the mustard or croton oil may be admissible. If otherwise, a long-haired dog may be rubbed on the spine with a combination in equal parts of strong aqua ammonia and olive oil; or it may have applied for some minutes wet cloths rather hotter than the hands can bear; or a light cauterization may be made with a Paquelin cautery. At this stage, too, bitters and phosphate of lime may be given. Trasbot has long used with the best results 1 grain doses of neutral, gelatinoid phosphate of lime, repeated two or three times a day. Iron may also be resorted to, or sulphate of zinc. Strychnia and electricity are also of great value as soon as the irritability of the spinal centres will allow of their safe employment. Massage and gentle exercise are important. From the first, attention must be given to obviate the retention of urine and fæces, and the strict antisepsis or asepsis of the catheter adopted to prevent infective cystitis and nephritis. Throughout the disease abundant nourishment of an easily digestible quality is demanded. Cleanliness, pure air and general comfort must not be forgotten. CHRONIC MYELITIS. SCLEROSIS. Sequel to acute. Result of sprains and spinal injuries. Symptoms: paresis on exertion, lameness in one or more limbs, knuckling, circumductive movement of feet, uncertain planting, dropping, worse if blinded, phenomena progressive. Lesions: sclerosis of cord; absorption of nerve cells and fibres, in gray horns, and columns, superior, lateral and inferior, cord, altered in color, unduly firm, in points softening. Stains deeply in carmine, lightly in osmic acid or hæmatoxylin. Meninges thickened, nerve roots atrophied. Diagnosis: previous acute myelitis; later muscular weakness, and paresis, under exercise; from embolism. Treatment: hopeless if advanced: progress delayed only. Good hygiene, tonics, open air, gentle exercise, pure water, grooming, succulent pasture, nourishing food, alkalines, common salt, phosphates.
