t^ Difea/es oceajioned hy Jnje£li 



ever it may be, the nature of it has not yet been determined 

 by certain obfervation. The pun6lure of flies and gnats, 

 efpecially when they have fed upon carrion, is in thofe dif- 

 trifls of a poifonous and inflamiiiatory nature : but thefe in- 

 fers are too perceptible, and their effefts fo fenfible, that we 

 cannot afcribe to them adifeafe which at firft is not attended 

 with any remarkable pain, and ii> this refpe6l it is particularly 

 diftinguifhed from the Svvedifh. 



The fymptoms of this difcafe, as generally obferved, are as 

 follows: — Perfons in perfeft good h(ealth, of all ages and of 

 both fexes, unexpcftcdly feel, while walking in the fields, an 

 itching accompanied withafmall hard tumour, which at firft 

 they are inclined to confider as the effe6l of the pun6lure of a 

 gnat or fly. It, however, fpcedlly increafesin fizeand hardnefs, 

 and before much attention has been paid to it, has proceeded 

 to fuch length, that a needle may be ftuck into the hard 

 fwollen part without the patient being feqfible of pain, unlefs 

 the needle is made to reach the found flefli. Jn the centre 

 , of the tumour there is then feen, for the moft part, a red or 

 blueifh point like the prick of an infeft, and in which, if 

 proper means be not foon applied, mortification or gangrene 

 cnfiies, and fprcads itfelf to the neighbouring parts. In the 

 firft ftagc of the difeafe, the patient has no internal affeftionsj 

 but as the inflammation of the tumour increafes (which, 

 however, is not attended with much pain), head-aghe, dejec- 

 tion, and internal uneafinefs take placp : but it is not impro- 

 bable that the fear of danger may contribute to promote 

 thefe fymptoms. Among cattle attacked by this difeafe, 

 uneafinefs and dejeftion are not obferved till it has attained 

 to the utmoft degree of it? violence. 



Cattle attacked by this difeafe generally die, partly becaufe 

 the tumours are obferved too late, and partly becaufe the 

 common people, being negligent, do not give themfelves the 

 trouble to apply a cure : on the other hand, among the hu- 

 maii fpecies, a cure feldom fails if the proper means have 

 been employed in time. The cure generally ufed by the 

 common people, as mentioned in Gmelin's Travels, is, to 

 run a long needle through the tumours in different direc- 

 tions, to rub into the punftures a mixture of fal-a,i;>moniac 



and
