been largely resorted to. Papayin and pepsin might be tried. 

 Also as anodynes digitalis, morphia, aconite and belladonna. 

 Finally tracheotomy has been employed when asphyxia seemed 

 imminent. 



PSEUDOMEMBRANOUS PHARYNGITIS IN SHEEP. 



Cause ; infected dust on susceptible subject ; inoculation. Symptoms ; 

 movement of jaws ; frothy lips ; salivation ; viscid nasal discharge ; diffi- 

 cult swallowing and breathing ; swollen tender throat ; extended head ; 

 anorexia ; cyanosis ; open mouth ; cough expels shreds of false membrane \ 

 asphyxia. Lesions. Treatment ; Glauber salts or muriatic acid in water ; 

 antiseptic fumigation and drinking water ; antisepsis of the pharynx. 



Roche-Lubin speaks of this disease as common in flocks, as 

 the result of moving them around for twentj'-four hours in a 

 narrow enclosure covered with dust which is raised in a cloud 

 and settles in the fleece so as to increa.se its weight. Tlie fever 

 and excitement caused by the constant driving and the local 

 action of the infected dust on the respiratory mucous membrane 

 is said to bring about the intense exudative inflammation. It 

 has been seen especially in the spring in young lambs .shortly 

 after weaning. Damman claims that he transmitted the disease 

 to sheep by inoculating the diphtheritic exudate of the calf. 



Symptoms. There were constant movements of the jaws, with 

 the accumulation of frothy .saliva round the lips or the drivelling 

 of this secretion from the mouth, the discharge of a viscid white 

 material from the nose, difficulty of deglutition, hurried, panting, 

 sntiffling breathing, swelling and tenderness of the throat, and 

 the occurrence of cough and the discharge of mucopurulent 

 matter whenever it was pre.s.sed. The head and neck are held 

 rigidly extended, the eyes are dull or glazed, the appetite is com- 

 pletely lost, the mucosae red and cyanotic and the animal weak 

 and unsteady upon its limbs. By the third or fourth day respi- 

 ration has become .so difficult that the mouth is held constantly 

 open, the tongue protruded and the painful convulsive cough 

 leads to the expulsion by the nose and mouth of shreds of false 

 membrane. Careful examination of the nose or of the fauces 

 may detect the grayish or yellowish patches of false membrane at 

 an earlier .stage. Death by asphyxia is common.
