Rh 10. For the Advancement and Propagation of Useful Learning.

11. For Increasing the People by Generation.

12. For preventing the Mischiefs of Plagues and Contagions. And withal, which of the said two states is most Practicable and Natural, for in these and the like particulars, do lye the Tests and Touch-stones of all Proposals, that can be made for the Publick Good.

First, as to Practicable, we say, That although our said Extravagant Proposals are both in Nature possible, yet it is not Obvious to every Man to conceive, how London, now seven times bigger than in the beginning of Queen Elizabeths Reign, should be seven times bigger than now it is, |31| and 49 times bigger than Anno 1560.

But if by Practicable be understood, that the present state may be suddenly changed into either of the two above-mentioned Proposals, I think it is
