792 INDEX OF DISEASES AND REMEDIES 



SCAB IN SHEEP continued. 



Dress carefully every itching part with creolin and alcohol each one 



part, soft soap eight parts. Non-poisonous (Frohner). 

 Within a few days immerse each sheep for three minutes in bath of two 



parts each of creolin and pot. carbonate and 100 parts water. Repeat 



bath in eight days. 

 Watch for any rubbing, examine each sheep twice a week, and, if 



required, apply the creolin dressing. 

 Decoctions of tobacco and stavesacre and solutions of arsenic, tar oil, 



and creosote are also used, both as lotion and bath. 

 The following formulae have been selected from a number tested in 



Germany: (1) Arsenious acid 10 parts, alum 200, water 1000 parts. 



(2) Arsenious acid 10 parts, potash 10 parts, water 1000 parts. 



(3) Arsenious acid 10 parts, alum 10 parts, vinegar 1000 parts, water 

 1000 parts. To avoid danger from absorption of arsenic by the skin, 

 sheep should not be dipped before the tenth or twelfth day after shear- 

 ing. Each sheep is immersed twice and brushed all over the body. 



All affected sheep should be isolated ; while, to prevent the spread of 

 the parasites, which remain alive for at least a week, racks, rubbing- 

 posts, and anything on which they may have lodged, are washed with 

 warm lysol solution (3 per cent.). 



SEEDY TOE OF HORSES. 



A perverted secretion of horn, with excavation between the laminal 

 sheath and outer wall of the foot, the space being partly filled with 

 soft mealy horn. It frequently follows laminitis. A similar 

 condition occurs in sheep. 



All diseased horn must be removed and the cavity disinfected. 

 Healthier growth encouraged by moisture, exercise, and blisters to 



coronet. 



A bar shoe relieves pressure. If space not large, recovery may follow 

 careful disinfection of the cavity. In other cases the outer wall 

 should be excised, and the exposed surface dressed with antiseptics. 

 To prevent deformation of hoof, the shoe must be removed frequently 

 and the hoof trimmed into shape. 



SHIVERING. 



Chronic myelitis with sclerosis of motor tracts of spinal cord, and 

 characterised by a peculiar spasmodic contraction of muscles of 

 hind or fore legs. 



Hereditary ; occurrence generally preceded by remote attack of 

 strangles, influenza, or pneumonia. Frequently symptoms difficult 

 to discover. Incurable. The horse may do moderate, slow work. 



SHOULDER SLIP (SUPRASCAPULAR PARALYSIS). 



Injury to nerve, or extensor muscles of the horse's shoulder. Rare in 



other animals. 

 Foment, rest, purgatives, massage : induced current to atrophied 



region. 



Blister when tenderness removed. 

 Douche with cold water ; exercise. 



SIDE BONE. 



Ossification of lateral cartilage of horse's foot. When uncomplicated 



seldom causes lameness. 



The treatment has been bar shoe, cold applications, rest, blisters, firing, 

 with neurectomy in chronic cases if feet otherwise sound. In cases 

 with contraction the wall may be grooved with knife or wedge firing- 

 iron, or divided in two or three places, and the foot afterwards shod 

 with a bar shoe. 



SORE-THROAT. See PHARYNGITIS.
