29. As for Physicians, it is not hard by the help of the observations which have been lately made upon the Bills of Mortality, to know how many are sick in _London_ by the number of them that dye, and by the proportions of the City to finde out the same of the Countrey; and by both, by the advice of the learned Colledge of that Faculty to calculate how many Physicians were requisite for the whole Nation, and consequently, how many Students in that art to permit and encourage; and lastly, having calculated these numbers, to adoptate a proportion of Chyrurgeons, Apothecaries, and Nurses to them, and so by the whole to cut off and extinguish that infinite swarm of vain pretenders unto, and abusers of that God-like Faculty, which of all Secular Employments our Saviour himself after he began to preach engaged himself upon. 30. Moreover, if it were agreed, what number of Divines, Physicians, and Civilians (that is, of men bred in Universities) were requisite to the publick service? As suppose 13000. in the present way, and perhaps not above 6000. in that way of Retrenchment which we propound; then supposing that but one in forty dyes _per annum_, it follows that less then 350. might suffice to be sent yearly out of the Universities: Where supposing they stay five years one with another, it followeth also that about 1800. is the number of Students fit to be allowed in the Universities at a time; I mean, of such as intend to make Learning their Trade and way of Livelihood. 31. I might intimate, that if 1800. Students were enough, and that if there were 40000. Parish Children and Foundlings in _England_, it were probable that one in twenty of them might be of excellent wit and towardness. Now since the Publick may dispose of these Children as they please, and since there is Maintenance in both Universities for above 1800. what if our Professors of Art were in this manner selected and educated? But of this but _in transitu_. 32. Hereunto may be added, that by reason of Loan Banks aforementioned, whereby the Credits and Estates of all Dealers may be known, and all the mysterious dangers of money prevented, and that by good Accompts of our growth, Manufacture, Consumption, and Importation, it might be known how many Merchants were able to mannage the Exchange of our superfluous Commodities with the same of other Countreys: And also how many Retailers are needful to make the subdistributions into every Village of this Nation, and to receive back their superfluities. Upon these grounds I presume a large proportion of these also might be retrenched, who properly and originally earn nothing from the Publick, being onely a kinde of Gamesters, that play with one another for the labours of the poor; yielding of themselves no fruit at all, otherwise then as veins and arteries, to distribute forth and back the blood and nutritive juyces of the Body Politick, namely the product of Husbandry and Manufacture.
