come to the place of Unites, for the fame will equally 
hold there alfo. Which the Reader may eafily apprehend 
without a long Difcourfe upon it. 
How far this Method may be coincident with fome of 
thofe before mentioned, I do not trouble my felf to enquire | 
nor whether, or for what caufes, all or any of thofe may be 
more eligible. My defign being only to lliew the true Na- 
tural ground, from whence fuch Rules of Approach are ( or 
might have been ) derived ; and by which ( if there be oc- 
caHon ) they may be examined. And if I have done this, 
It is what I did propofe. 
In AfTeded Equations ( efpecially where the Coefficients 
are great, and fbme Affirmatives, others Negatives,/ the 
Cales will be more perplexed. And to Multiply Rules for 
each Cafe, would ( I conceive ) increafe the Trouble, with 
no great Advantage. Which therefore I leave to the Prudence 
of each (as occafion lliall require ) to take fbme Intermedi- 
ate, between a greater and a lefler. Or if they pleafe to 
accommodate that above mentioned ( out of Commerce E- 
fifiol.) to the prefent cafe, which is there applied to a Cafe 
not left intricate. Or to make u(e of fbme of the Methods 
delivered by others to this purpofe. Where this f withal ) is 
to be confidered. That fuchAfFe^ed Equations are capable 
of more Roots than one, according to the Number of Di- 
mcnfions to which they arife.
