156 LAMENESS IN THE HORSE. 



9. Enlarged Inguinal Glands. — Give rise to similar symp- 

 toms as seen under 8, and is recognized by palpation. 



10. Fistulous Withers. — If of some standing, destruction 

 or disease of elements essential to normal locomotion occurs. 

 The continuous discharge and local examination will estab- 

 lish a correct diagnosis. 



11. Sternal Fistula — The somewhat doughy but not very 

 painful swelling between the fore-legs, with its fistulous 

 openings, causes the animal to straddle in front. The 

 local examination will leave no doubt as to the seat of the 

 lameness. 



12. Wounds and Inflammatory Conditions of the Shin and 

 Underlying Tissues of the Organs of Locomotion. — Injuries, 

 sufficiently severe to cut through muscles, tendons and 

 nerves, swellings resulting from infection, are all apt to bring 

 on more or less intense lameness. Inspection and palpation, 

 if carefully executed, will readily decide upon the cause of 

 the lameness. 



13. Osteoporosis. — Intermittent lameness, first in one, 

 then in the other leg, without distinct symptoms as to its 

 origin, makes this an obscure trouble. The evolution of 

 this disease is slow, and months may pass before marked 

 symptoms appear. But if the epiphyses of the bones swell, 

 especially the tibia and bones of the head, etc., the true 

 cause of lameness can soon be located.
