To the Reader.

_Learned Reader!_

_These Tracts are the fruits of som of my Sollicitations and
Negotiations for the advancement of Learning. And I hope they may in
time becom somwhat effectual to rais thy Spirit to the exspectation of
greater things, which may bee raised upon such grounds as these. All
which are but preparatives towards that perfection which wee may exspect
by the advancement of the Kingdom of Christ, wherein the Communion of
Saints, by the graces of the Spirit, will swallow up all these poor
Rudiments of knowledg, which wee now grope after by so manie helps; and
till then in those endeavors I rest in the Truth._

Thy faithfull and
unwearied servant

A SUPPLEMENT TO THE _Reformed School_.

_Loving freind!_

You have offered to mee that which I confess I did not reflect upon,
when I wrote the discours you have Published under the name of a
_Reformed School_; which is, that som may think by the waie of
Education, which I propose all Universities and eminent places of
Learning might subtilly bee undermined and made useless, becaus therein
a waie is shew'd how to initiate youths not onely to the Principles of
all Religious and Rational knowledg, and in the Exercises of all Moral
virtues, but in the grounds of all Civil emploiments, so far, as will
make them fit for all profitable undertakings in humane societies,
whence this will follow (in their apprehensions) that they shall have no
advantage by beeing sent to anie Universities, to attein anie further
perfection: becaus the Universities will not bee able to add anie thing
unto them, which by their own Industrie, they may not afterward attein
anie where els, as well as there. Truly it never came into my thoughts,
either directly or indi
