WHat moved the learned and worthy Author of this work to 
enrich the world with fuch an Edition of thefe three Anci- 
ent Mathematicians, the Reader will find in his general Preface to 
Jyehimedes. What he hath performed^ infhort is this : He hath 
delivered thefe three Books in a brief Symbolieal method of Ex- 
preffion, purfuant to the Senfe, Propofitions^ and Demonftrations 
of the Ancients ; tinlefs where he thought fit to enlarge, and other-

ciples of his own, purfuing herein his own former method , in 
which, fome years ago, he publiflit an entire Euclid in 80. 
Befides, this Edition contains a new Verfion of Archimedes his 
Lenmata^ which were not formerly publifli't with the reft of Ar- 
chimedes\ Works ; though to be found in Forders Mifccllanies,and 
at the end of 'job. Jlfh^ BoreSh Edition of the three latter Books
