And then, in regard it often happens, thati£qua-

thod of Vieta^ as in Cubich^ laft above mentioned. 
The whole Dodrine is illuftrated with great varie- 
ty of choice Examples , and the Author intending 
hereafter to treat more fully of Algebra^ promifeth 
to extend his methods to Equations of higher de- 
grees, and to render the fame more general. The 
remainder of the Book doth principally treat oijign*^ 
rate Arithmetick, 
And here we think it fit to intimate, that divers 
good Treatifes of Algebra have been lately publifli't 
in Low Dutch. This Author cites Queftions out of 
the 3d Century of Qmfiions in the Officina Algebra of 
Marten Wilh^ns^ which we have not feen. Gerhard 
Kinkhnyfen hath of late years publifhM feveral di- 
ftinft Q^art0'Books^Di%. A TraSi of Analytical Co- 
nich^ : A ColleSiion of Geometrical problems^ Analyti- 
cally folv'd 5 as alfb fuch an acceptable Introduction to 
Algebra^ that by the encouragement of fome of the 
R. Society it hath been Tranflated into Latine ^ and 
fitted for the Prefs , to which will be annexed the 
Methods and Examples of Fergufon about the Roots 
of Equations. And we have little reafon to d0ubt> 
but that the )uft now mention d IntroduStion will
