HEEEDITARY UNSOUNDNESS. 707 



irritated b)' the gear, it should be regarded as an unsoundness. See 

 following paragraph. 



Skm diseases and wounds. — Cases under this heading should be 

 decided according to the principles laid down by Mr. Baron Parke 

 (p. 695). 



Sole, weak. — When this condition is a result of disease, it is an 

 unsoundness ; but when it is a congenital defect which does not cause 

 lameness, it is not an unsoundness. "Mere defective formation, how- 

 ever, not producing lameness at the time of sale, is not, in my opinion, 

 unsoundness " (Mr. Justice Cresswell, in Bailey v. Forrest, Carrington 

 and Kirwan's Reports, vol. 2, p. 131). 



Sore-shins (p. 246). — This form of bony deposit, unless when 

 very exaggerated, seldom later feres with the animal's usefulness, after 

 the inflammation has subsided. 



Speedy cutting (p. 90). 



Splints (p. 231). 



Split-hoof (]). 183) may or may not be unsoundness, according as 

 it does or does not injuriously affect the animal's usefulness. 



Surfeit (p. 160). — See " Skin Diseases " on tliis page. 



Tetter, dry (p. 161).— See "Skin Diseases." 



Tetter, hu?nid (p. 161). — See "Skin Diseases." 



Thoroughpin (p. 326). 



Tread {^. 90). 



Warhles. — See remarks by Mr. Baron Parke (p. 695). 



Warts. — See " Skin Diseases "' on this page. 



Weaving. — This is a vice ; see p. 564. 



Windgalls. — If a windgall is soft and fluctuating to the touch ; 

 shows no sign of inflammatory action ; does not injuriously affect the 

 horse's movements in any way ; and does not become heated after 

 work ; its presence may be i-egarded as no detriment to the animal's 

 soundness, especially, if the horse is aged. 



Wind-sucking (p. 564). 



Worn legs.—^ee "Filled Legs" (p. 706). 



Hereditary Unsoundness. 



The term, "hereditary unsoundness," is so frequently applied to 

 diseases which, like roaiing, spavin and sidebones, are acquired after 

 birth, that I am forced to include under this heading several diseases, 

 in which the only part played by heredity is that of predisposition, as 

 for instance, by the transmission of faulty conformation (p. 254) and 

 other causes (pp. 383 to 385). Bent fore legs, twisted pasterns, and 

 excessive convexity of the cornea, being faults of conformation, are
