particular, without having been able to difcover the 

 foramen. The late Mr. Baker however, feveral years 

 after, convinced him of its exiftence. He then re- 

 traded his former fentiment, and with great candour 

 and judgment gave it as his opinion, that, as amongft 

 ferpents, only fome particular fpecies are poifonous, 

 and have teeth that are perforated for the emifllon of 

 their poifon, viz. the Rattle-Snake, the Viper, and 

 others, fo amongft Spiders fome kinds only may be 

 poifonous, viz. fuch as are provided with perforated 

 flings. 



The Eyes of Spiders differ very much from thofe of 

 moft other infe&s ; and are different both in number 

 and difpofition in the feveral fpecies. The prefent 

 fpecies has eight eyes, which are difpofed fomewhat in 

 the form of an oblong fquare. Of thefe the two mid- 

 dle ones are larger than the reft, and perfectly round; 

 the others are of an oval fhape.
