INDEX OF DISEASES AND REMEDIES 791 



ROARING or WHISTLING continued. 

 Tracheotomy also affords relief. 

 Strychnine persisted with for weeks in the earlier stages appears to 



arrest and may prevent the muscular wasting. 

 Of various surgical operations attempted, excision of the left laryngeal 



ventricle has given the best result. 



ROT IN SHEEP. DISTOMUM HEPATICUM. See WORMS. 



SADDLE GALLS. 



Bruises from badly-fitting saddles or harness. 



Relieve from weight and prevent friction. 



Apply hot compress and antiseptic dressings. 



Swollen sebaceous follicles in the early stages are reduced by friction 

 with soap liniment ; in chronic cases by fomenting, lancing, or 

 cauterising with undiluted carbolic acid. 



Portions of dead tissue or exudate constituting sitfasts should be dis- 

 sected out, and the wound treated in the usual way. 



SANDCRACK. 



Fissure in horn of horse's foot, usually on inner quarter of a fore- or 



toe of a hind-foot. 



Remove shoe, thin wall on each side of fissure, cleanse and disinfect. 

 Fomentation, poultice, and rest relieve pressure, inflammation and pain. 

 When these abated, clamp or wedge the fissure, or groove the wall 



transversely or obliquely to the direction of the crack, and blister 



coronet. 

 Bar shoe, made to relieve fissured horn from pressure and concussion. 



Dress hoof frequently with wood tar. 



SEPTIC INFECTION. 



A febrile state, the result of the circulation in the blood of patho- 

 genic organisms or the toxins to which they give rise. The 

 organisms multiply at the seat of inoculation, and have the power 

 of entering the circulation, and thus forming secondary infective 

 foci. Infection occurs in puerperal metritis in cows and ewes, 

 in the fever occasionally following castration and other surgical 

 operations, as well as accidental wounds in horses (open joint, 

 gathered nail, etc. ). 



Arrest if possible the primary source of infection. 



Cleanse and render aseptic any wound. Excise necrosing tissue. 



Corrosive sublimate solution 1 to 1000. Zinc chloride 1 to 100. 



Administer antiseptics, antipyretics, creolin, sulphites, quinine, anti- 

 streptococcic serum. 



Generous dietary ; milk, eggs, oatmeal gruel, beef tea. 



Alcoholic stimulants, acids, and bitters. 



SARCOMATOTTS TUMOURS. 



Are chiefly composed of embryonic or immature connective tissues ; 

 they contain blood-vessels, but neither nerves nor lymphatics have 

 been clearly made out ; they differ greatly in appearance, rapidity 

 of growth, and malignancy, and occur in all the lower animals. 

 In the earlier stages, especially if likely to interfere with any important 

 function, removal by the knife should be attempted. 



SCAB IN SHEEP. 



Skin irritation, inflammation and scabbing, caused by Psoroptes. 



See ACARI and MANGE. 



In all bad cases the sheep should be bare shorn and affected parts soaked 

 with pot. carbonate dissolved in twenty parts water before the 

 insecticide is applied.
