He begins with that of Ptolm/s Harmonicks^ the 
moiV confiderable of all the Greek Maficians. This he 
had fi*ft publifti'd in the Year 1682, (and hath now re- 
printed) out of 11 or ii Greek Manufcript Copies, 
(having been never before nubhfhed in Greek, and but 
very Imperfeftly in Latine, by GagovittuSy more than an 
Hundred W^ars ago.) To this he gives a new Latine 
Tranjlationt with large Notes; giving Account of the 
Various Readiftgs in the feveral Copies, and theReafons 
of what Emendations he thought neceflary to make ; 
with clear Explications of what might feem difficult in

Latine ; Marcus Meibomius having formerly publiflicd 
divers of them in the Year l6s^; and the remaining 
Three (which he feems to have intended, but did not 
publilh) being now added. 
The next Piece is Archimedes' s Arenarius^ or '^oLfjLfjul' 
rrw^, (which he had firfl publiflied in the Year 1676,^ Of 
this we had a GreekE dition of Hervagius, publifhed at 
Bafd^ in the Year 1544; which feems to be done by 
Hervagius with great Care and Fidelity, but out of a
