vcflels that are ftung, that of thc 
aliment with which the feorpion 
was fed, the feafon of the year, and 
many other contingences, raay 
cohtributc to it. The efficacy of 
the rcmedy employed, fuch as oil 
of feorpions, and others, is perhaps 
only due to the fmall degrcc of ac- 
tivity, or to thc total abfencc of 
thepoifon. In climates wherc thc

ful, thc fureft remédies would be 
volatile alkalis. They fay, that in 
1 129, there appeared at Bagdad, in 
Arabia, winged feorpions with a 
double tail, v/hich füled ail thc

miner. La nature des vailTeaux 
piques, celle de l’aliment dont s’eft 
nourri le feorpion, la faifon et plu- 
fieurs autres incidens peuvent y 
contribuer. L’efficacité du remede 
que l'on emploie, tels que ceux 
d’huile de feorpion & autres n’eft 
peutetre due qu’au peu d’aélivité 
ou à l’abfcncc totale du poifon. 
Dans les climats oîi l’effet de leur 
piqueure eft le plus redoutable, 
les remedes les plus certains fe- 
roient les alkalis volatils. On dit 
qu’en 1129 il parut à Bagdad en 
Arabie des feorpions ailés avec une 
double queue, qui remplirent tous 
les habitans de terreur et firent 
beaucoup dédommagé.
