may be detected minute papules, surmounted in some cases by 

 vesicles. When rubbed gently, the animal expresses its pleasure 

 by rapid movements of its lips or even of its feet or body, as if 

 anxious to take part itself in the friction. L,eft to itself the 

 affected sheep rubs its face on the fore limbs, or other objects and 

 scratches it vigorously with its hind feet, producing abrasions 

 and exudates, which latter dry into scabs and crusts, at first thin 

 and isolated, but later, thick, hard, resistant and continuous, 

 over the whole affected .surface. This incrustation becomes more 

 or less discolored by exuding blood, and by extraneous matters of 

 many kinds deposited in rubbing the sores. 



Neglected, the skin becomes thick, rigid and plicated, the lips 

 unable to act in prehension of food, the eyes watery or closed by 

 a mucopurulent discharge, and the ears the seat of hsematoma 

 owing to the violent scratching. 



Treatment. Treated early, the disease is easily cured by the

In advanced cases a thorough smearing for several days with 

 sulphur ointment to soften the scabs, and the removal of the latter 

 with the aid of warm soap suds, may well preface some other 

 form of treatment. It may further be advantageous to cover the 

 face with a thick cloth or leather to protect the applications, and 

 to obviate further irritation by scratching and rubbing. 



As an essential part of the treatment the removal of the flock 

 to a non-infested sheepfold or pasture or the thorough disinfection 

 of that in which they have been kept is essential. All rubbing 

 places, stones, posts, fences, trees, gates, etc., mu.st receive special 

 attention and dressing. 



In France the movement or public exposure of all sheep affected 

 in this way is forbidden, and with a disease so easily recognized 

 it should be made a misdemeanor to ship the affected animals by 

 any public conveyance, to expo.se them on any public highway 

 or unfenced place, or to take them to any public market, show or
