And as this Experimental way will afford much help to our 
Public^ duties, and Civil aUions, fo it improved to be very ufe-

private motions and paffions, by keeping them from idlenefs 
with full and earneft employments, and by poffeffing them with

From hence our Author proceeds to make a defence of the 
foyal Society » and this new Experimental Learning, in relpeCl;

Trades , which have been heretofore found out, and adorned. 
This Argument he difpatches in a clear Refolution of thefe
