570 EPITOME OF MODERN TREATMENT 



100 yards to cause them to urinate. Ammonium and sodium benzoate, in 

 the horse, or hydrochloric or sulphuric acid. 



In dogs, lithium salts may be placed in the drinking water, or lycetol 

 (dose, gr. 15). These agents may prevent calculus formation but no drug 

 will dissolve calculi in the body. 



In oxen — Work forward urethral stone by massage or do ischial ure- 

 throtomy. 



In sheep — Stroke the urethra to remove stone or sediment about meatus. 

 Success is secured only by amputation of the penis in many cases; lithotomy, 

 lithotrity, or urethrotomy are often required. To relieve pain and spasm 

 in urinary calculus, give hot enemata, and morphine and atropine, under 

 the skin. 



Canker op Ear. See Otorrhea. 



Canker op Feet in Horses. 



Throw the animal and remove by actual cautery or knife all the diseased 

 horn of the sole and frog down to the sensitive tissue. Tight bandage 

 above fetlock for a few hours to prevent hemorrhage. Dress foot with one 

 of following: — Salicylic acid; stick silver nitrate; formaldehyde (10 per 

 cent.); equal parts of alum, or tannic acid, and iodoform; creolin or iodine 

 ointment (5 per cent.); equal parts of zinc, copper and iron sulphates, 

 vaseline to make paste, and enough creolin to equal 5 per cent. Then 

 cover with tow, false sole of leather or iron, and shoe. Dress daily with 

 one of above agents and remove any specks of canker, if present. When 

 horn forms, dress with tar or calomel. After first days of treatment animal 

 may do best at work. 



Capped Elbow, Hock, Knee. 



Treatment as for bursitis (see Bursitis) in acute stage; in bursitis (of 

 perforatus) or capped hock, apply high-heeled shoe; in capped elbow, pre- 

 vent increase of trouble by use of heel or ring pad; when large amount of 

 induration has formed it must be excised. 



Catarrh. See Coryza, Rhinitis^ Acute. 



Catarrh, Chronic. 



Symptomatic of chronic rhinitis, disease of accessory sinus, and guttural 

 pouches, glanders, carious teeth and new growth. Isolate and test for 

 glanders. In general give tonics as iron and arsenic, graze or feed from 

 floor, rest from work and fresh air. Inhalations of phenol or compound 

 tincture of benzoin. Treatment mainly surgical — trephining, drainage and 

 irrigation of maxillary sinus; hyovertebrotomy in disease of the guttural 

 pouches in sheep, see Mestrus larvw. 



Catarrhal Fever. See Maligant Catarrhal Fever of Cattle. 

 Cerebral Anemia. 



Shown by fainting (syncope). See Syncope. 

 Cerebral Hemorrhage. See Apoplexy, Cerebal. 

 Cerebral Hyperemia. 



Raise head, ice bag to poll; venesection, 4 to 8 quarts in horse; veratrum. 

 Mustard paste to legs and bandage. Warm covering; croton oil; dark, 

 quiet quarters; if swallowing possible, gruels and mashes. 



Cerebritis. See Encephalitis. 



Cerebro-Spinal Meningitis. 



Chiefly enzootic and epizootic in horses and sheep. See also Encephalitis 

 for general treatment. Quiet, dark, cool quarters ; slings for horses if animal 

 cannot stand. Lumbar puncture behind 6th lumbar spine to relieve pressure 

 and for cell and bacterial examination. Physic ball with calomel for horse, 

 or barium chloride intravenously if the horse cannot swallow; ice to head, 

 ergot, atropine, strychnine, cantharides; cathartics; water via stomach tube; 

 catheterize; avoid moldy food and stagnant water; secure food from other 

 regions; dry stable; disinfect quarters after occupancy.
