leader of the flock has in many places a bell hung ; 
round its neck, which the others will conftantly 
follow: it is fubjeét to many difeafes: fome arife 
from infects which depofite their eggs in different 
parts of the animal; others are caufed by their 
being kept in wet paftures; for as the fheep re 
quires but little drink, it is naturally fond of a dry 
foil. The dropfy, vertigo (the pendro of the 
Welfh) the pthifick, jaundice, and worms in the 
liver * annually make great havoke among our 
flocks: for the firft difeafe, the fhepherd finds a 
remedy by turning the infected 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 
infects: like the horfe it has its peculiar Oefrus or 
° Gadfly, which depofits its eges-above the nofe in 
the frontal finufes; when ‘thofe turn into mag- 
cots they become exceflive 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 fheep, by trepannine and taking 
out the maggot; this practice is fometimes ufed 
by the Englifb fhepherds, but not always with the 
fame fuccefs: befides thefe infects, the fheep is trou- 
bled with a kind of tick and loufe, which magpies 
and ftarlings contribute to eafe it of, by lighting 
on its back, and picking the infects off.
