34 SHEEP. Class I. 



leader of the flock has in many places a bell hung 

 round its neck, which the others will conflantly 

 folloy/ : it is iLibje6l to many difeafes : fome arife 

 from infects which depofite their eggs in difi'erent 

 parts of the animal ; others are caufed by their 

 being kept in wet pad u res ; for as the fheep re 

 quires but little drink, it is naturally fond of a dry- 

 foil. The dropfy, vertigo (the pendro of the 

 Welfli) the pthifick, jaundice, and worms in the 

 liver * annually make great havoke among our 

 Rocks : for the firft difeafe, the fhepherd finds a 

 remedy by turning the infeded into fields of broom ^ 

 which plant has been alfo found to be very effica- 

 cious in the fame diforder among the human 

 fpecies. 



The fheep is alfo infefted by different forts of 

 infecls : like the horfe it has its peculiar Oeftrus or 

 Gadfly^ which depofits its eggs above the nofe in 

 the frontal finufes ; when thofe turn into mag- 

 gots they become excefTive painful, and caufe thofe 

 violent agitations that we fo often fee the animal 

 in. The French fhepherds make a common prac- 

 tice of eafing the Iheep, by trepanning and taking 

 out the maggot; this pra6lice is fometimes ufed 

 ' by the Englifo fhepherds, but not always with the 



fame fuccefs: befides thcfe infedls, the fheep is trou- 

 bled with a kind of tick and loufe, which magpies 

 and flarlings contribute to eafe it of, by lighting 

 on its back, and picking the infects off.
