WHen the Publ di^r intended to give notice to the Woili 
oi Mr, Bohh ['s B ok very lately come abroad , con- 
cerning xh^^^drMHre of ths Circle ^e, he foon found another^ 
containing both that sni the Confutation of it together. 
The Author of this Confutation obferveth two grand mif- 
takcs in Mr, Hobhf s Tra6l-, the firft in the Demonftration of 
his firft Propofidon , wherethrfe words , Aut ergs in Tmn-

Line drawn parallel to the Bafe Qjf , a little nearer to the 
Vertex A i may cut off a like Right-angled Triangkf a little lefs 
then A Y Q) which may be equall to the Senior A G L. 
Befi ies this (which overthrows all , in the examiners ladge- 
msnt j the other great miftake of M. Hehb^ is alledged to be 
in che Demonftration ohht Jecond Propofition ^ where (fup^ 
pofiag by the firft Propofition a fquare found eqaall to a C rcle ) 
heargues. That, becaufe the Square takes in as much of what 
iS left out by the Circle, as the Circle takes in of what is left 
out by the Square 5 therefore a Cube anfwering to that Squ - re, 
compared withaSphere anfwerin|to that Circle, will doe fo 
too : (which would have been well argued , laith the Examiners 
of a Cylinder on that Circle , of equall height with a Cube oa
