Another fpecies of fly fhould not be patted 

 over, which is one of the greateft nuifances of 

 the foreft. In form it is not unlike the com- 

 mon black fly, and about it's fize ; but it's 

 colour is different. It is a bright-coated, 

 brown infect; well-cafed; ftrongj and very 

 retentive of life*. It has a fide-long, crawling 

 motion, like a crab. The horfe is it's favo- 

 rite quarry ; tho it attacks the cow, and other 

 animals. You may fometimes fee hundreds 

 of thefe infects nettling under the tail, and 

 belly of fuch horfes, as are patient of them; 

 as the New-foreft horfe commonly is by 

 long fufferance. But to fuch horfes, as are 

 unaccuilomed to thefe teafmg infects, they 

 are a grievous torment ; tho it is doubtful, 

 whether they are blood-fuckers, or fubfift 

 only on fuch juices as exude through the 

 Ikin. In this latter cafe they offend the 

 horfe only by tickling him ; for which opera- 

 tion their legs are well adapted, appearing, in 

 a microfcope, armed with fharp talons, like 

 pot-hooks.
