purpofe, in order, if poflible, to difcover the faline particles 

 contained in it, ^vhich alone, as it feenis probable, do render this 

 liquid poiibnous in lb great a degree ; but, with all my attention, 

 I could not perceive any thing in it particularly worthy of noting. 



This liquid, being in a very finall quantity, and alfo being 

 fpread very thin, in a Ihort time, all the moiflurc of it .was evapo- 

 rated, leaving a kind of thick gummy matter, mixed with various 

 different particles, to which I could not afTign any particular 

 figure. Hereupon, I, without lofs of time, made a pun6lure on my 

 finger with a needle, and applied a fmall portion of the blood 

 wiiich illued from the part, to this poifonous fubdance, in order 

 to fee, whether the blood would undergo an}'^ alteration by the 

 mixture. But, nothing of that kind appeared, for I could not

The next morning, I diflecfed the tail of this Scorpion, and, 

 from each joint, I took out two flelhy mufcles, of a very white 

 colour, each of which was compofed of a great number of very 

 fmall oblong particles, terminating at the extremity of the mulcl

 mufcles was a kind of veflel, fliaped in the middle like a bladder, 

 and this, I concluded, was deflined to convey the poifon to the 

 extremity of the tail. Thefe flelhy mufcles were furnilhed with 

 annular parts, or rings, ferving to extend and contra6l th.e mufcle. 



Thofe eyes whio'a were fjtuated on the upper part of the head, 

 I placed before the microfcope, whereby I faw how perfectly the 

 tunica cornea, or horney coat of the eye was formed ; for through 

 it I could fee all the furrounding objects (though wonderfully 

 diminifhedj fo diftin<5fly, that I could not contemplate the fpedtacle 

 without admiration ; but this pleafmg fight was not of long conti- 

 nuance, for the tunica cornea foon dried and flirivelled up. 



Upon opening the belley, I could not form any judgment of the 

 inteftines, by reafon that they had begun to decay, except that I
