DISEASES OP THE OX AND SHEEP. 199 



to bear in mind that beasts, if turned into the same field, do not 

 become affected in any way, but, on the contrary, remain per- 

 fectly healthy. Again, if the affected sheep are taken to places 

 favourable for recovery and suitably treated, being put into a 

 dry grass field, for instance, and well looked after, they will 

 get well, and, moreover, if healthy sheep are put with them, 

 they will remain quite healthy. 



Again, the sheep afflicted with this malady do not secrete a 

 large quantity of saliva, nor do they smack the lips, nor is 

 there any vesicular eruption to be seen either inside or outside 

 the mouth, all of which symptoms are, as we have seen above, 

 to be noted in typical cases of foot-and-mouth disease. 



Before concluding, we may just briefly state the symptoms. 

 The sheep go lame suddenly, the foot and the coronet are hot 

 and painful to the touch, and occasionally very small scabs 

 may be present on the nose or on the lips. The appetite is not 

 as a rule markedly impaired. The pain which ensues from 

 progression causes the sheep to sit and lie down. Sometimes 

 it may be found difficult to move them, and even when they do 

 move, they will, perhaps, merely limp on for a few yards, and 

 then squat themselves down again. At this time the coronets, 

 if examined, will be seen to be affected with acute erythema, 

 while suppurative laminitis breaks out over the coronet in such 

 an extreme form that even the hoof may come off. As for 

 the mouth, the outside of it is sore ; but the tongue is perfectly 

 healthy, and, as we said above, there is no extra discharge of 

 saliva. 



This disease which we have described, our readers will see, 

 is distinct from foot-and-mouth disease in various particulars, 

 and from foot-rot in that the mouth is affected, and also that 

 in this disease there is no ulceration of the foot like that of the 

 contagious foot-rot, which disease we now proceed to consider. 



FOOT-ROT IN SHEEP. 



In due course we now come to a consideration of that 

 important disease which is known as foot-rot of sheep. Now, 

 at the outset, it is well to draw a clear distinction betwixt that 

 simple kind of foot-rot with which sheep are liable to be 

 afflicted when they are kept on wet grass-land — especially if, the
