great many Notches in it, and efpecially when the Razor 
meets with a ftiff rugged Hair, that was not fufficiently 
fuppled with Water. However it be, 1 never yet faw a

Delft in Holland, June 21, 1701. 
IN the Account of Books for the Months of March and 
April for this prefent year, I met with a Book whofe 
Title in EngUJhrms thus: Hijiorical and Philological Mif' 
cellanies^ coUeSled hy Mr Vigneuil-Marville, the 2d part 
printed at Kotterdam for Elias Yvans, 1700. Wherein, 
p. 276. he that gives the Account of Books fays thus : 
The Author in the 407th page of his Book tells us what 
a wonderful Magnifying Glafs he met with at a Virtuofo's 
in London^ whofe Excellencies will feem Incredible to 
nioft that hear them ^ and yet he Inftances in fome Par- 
ticulars of his own Obfervations, and pretends that he can 
thereby difcover the Atoms ot Epicurus^ the Materia Sub* 
tiik of Defcartes, the Exhalations of the Earth, the Per- 
fpirations of Bodies, and the Influences of the Stars. 
The man feems by his Writings to be a Papift. 
This Relation feems to me wholly Paradoxical, and I 
do earneftly intreat you, Sir, to tell me whither you know 
any thing of thefe wonderful Sights, for I could never be 
perfwaded that we can penetrate fo far into the Secrets of 
Nature 5 and therefore I rather think it ^to be a Fable 
than Truth.
