668 APPENDIX. 



the appearance of being filled with small tubercular deposits. These 

 parasites are not always confined to the lungs. They are commonly 

 found in the intestines, giving evidence of similar post mortem appear- 

 ances as the lungs. 



Symptoms. These will be according to the location of the parasite. 

 In the lungs the symptoms are those of bronchitis ; if they extend 

 to the intestines we shall find emaciation and dysentery. The stools 

 may contain the worms, and in fits of coughing the worms may also 

 be thrown off, especially in lambs when the parasite is contained in 

 the bronchi. This disease does not always cause death, as seen by 

 the post mortem appearance of the lungs of sheep, which, in life, 

 appeared to be in perfect health. The parasite had long been iu capsule 

 in the lung tissue, the tubercular mass having gone on to caseation. 



Treatment. This must be preventive and curative. All the 

 healthy ones should be removed to high, dry pastures, care being taken 

 that no attendant go from diseased to healthy animals. The diseased 

 should be removed to a new dry field. The old pastures, if possible, 

 should be burned over to destroy any liability to the spread of the 

 disease. Curative treatment should consist in giving each animal, 

 according to size, one to two drams of Spirits of Turpentine, injected 

 into the lumen of the trachea, with hypodermic syringe, once a day 

 until improvement is noticed. If there are any bowel symptoms give 

 same dose of Turpentine with twice the quantity of oil by the mouth. 



FOUL IN CATTLE. 



This is an infectious disease affecting all animals having the cleft foot, 

 but is more commonly found in cattle. The disease is due to a germ. 

 Animals kept in low, damp, badly managed stables, or allowed to run 

 on low, damp ground are most liable to become affected, as such 

 grounds and conditions are favorable to the development of the germ, 

 which gains admission to the soft structures of the foot by means of a 

 wound caused by contact with rough surfaces, or the feet becoming 

 weakened by constant moisture so that they lose their resisting power. 

 When the germ gains admission into the foot it burrows deeper and 

 deeper, and the animal's foot may slough off should the disease be 

 allowed to continue. Under favorable conditions, this disease after 

 gaining admission into the herd may go through the entire herd. 



Sym.ptoms. At first the animal shows slight pain in moving about. 

 L,ater the limbs will begin to swell, with increased temperature. Under 

 examination the foot will be found sensitive to the touch, and an abra- 

 sion of more or less extent will be found usually in the cleft of the. 

 foot, or maybe at the junction of the hair at the heel. This abrasion 

 in the early stage will have a watery appearance, with an offensive 

 odor, and later pus will be found in quantities.
