412 0$ large Spider's Eyes. 
It would not be ftridly honeft to pafs over 
this Subjed, without declaring, in juftice to 
the Memory of Mr. Leeuwenhoek , that not¬ 
withstanding! have fometimes thought him 
miftaken in his Defcriptions of Things exa¬ 
mined by the Microfcope, it has feldom hap¬ 
pened, but that afterwards I have found fuch 
his Defcriptions true, and that the Objeds I 
had formerly judged from were not exadly 
of the fame Sort, or in the fame Perfedion 
as his : And this I hope will make others 
cautious, not immediately to determine in 
Matters of this Nature from a fingle and per¬ 
haps a flight Examination ; which I believes 
too often has been the Cafe. 
Having fatished myfelf concerning the 
Fangs of this Spider, I proceeded to an Ex¬ 
amination of its Eyes, which I found to ba 
eight, fituated on the Summit of the anterior 
Part of the Body : for I think a Spider can¬ 
not properly be faid to have any Head. I 
cut out a Portion of the Shell or Cruft in 
which the Eyes were placed, that I might 
bring them with more Convenience to' my 
Glades. And I foon faw that the two Mid¬ 
dle Eyes were much larger and more re¬ 
markable than the reft, and feemed exadly 
round, and that the three fmall ones on ei¬ 
ther Side were oval. The Difpofition, pro¬ 
portionable Size, and Appearance of them all 
together, may be feen at El, 
Aftes?
