Heavy lofles have been fuftained from the 

 havoc made by the above diforders, which 

 lhould be carefully guarded againft. 



When a fheep is attacked by the diforder 

 called the black-leg ; if he be fat, the fooner 

 you kill him the better -, I never knew one 

 cured* You will firft perceive a black fpot near 

 the ftifle joint, and the fheep will become fo 

 lame as fcarcel.y to be able to move : this fpot 

 generally increafes very rapidly, and foon turns 

 to a mortification* I have tried fomentations and 

 many other remedies ; but all in vain. I mult 

 own that I have never heard a rational explana^ 

 tion given of the caufe of this diforder -, nor can 

 I account for it. I have fometimes been tempt- 

 ed to attribute the appearance of the diforder 

 to fome external injury by a blow : but on re- 

 flection I have dropped that opinion : for it 

 cannot be a bruife. It is more probable that 

 it is caufed by the bite of fome venomous rep- 

 tile, as it often happens that a number of (heep 

 have it in t"he fame paflure. 



Blindnefs in {heep is a very common difeafe, 

 and is brought on by a cold falling into the eyes. 

 The mod difagreeable confequence enfuing 

 from it is the danger of the fheep's drowning
