There are, besides the above-mentioned, innumerable Retainers to Physick, who, for want of other Patients, amuse themselves with the stifling of Cats in an Air Pump, cutting up Dogs alive, or impaling of Insects upon the point of a Needle for Microscopical Observations; besides those that are employed in the gathering of Weeds, and the Chase of Butterflies: Not to mention the Cockle-shell-Merchants and Spider-catchers. When I consider how each of these Professions are crouded with Multitudes that seek their Livelihood in them, and how many Men of Merit there are in each of them, who may be rather said to be of the Science, than the Profession; I very much wonder at the Humour of Parents, who will not rather chuse to place their Sons in a way of Life where an honest Industry cannot but thrive, than in Stations where the greatest Probity, Learning and Good Sense may miscarry. How many Men are Country-Curates, that might have made themselves Aldermen of _London_ by a right Improvement of a smaller Sum of Mony than what is usually laid out upon a learned Education? A sober, frugal Person, of slender Parts and a slow Apprehension, might have thrived in Trade, tho' he starves upon Physick; as a Man would be well enough pleased to buy Silks of one, whom he would not venture to feel his Pulse. _Vagellius_ is careful, studious and obliging, but withal a little thick-skull'd; he has not a single Client, but might have had abundance of Customers. The Misfortune is, that Parents take a Liking to a particular Profession, and therefore desire their Sons may be of it. Whereas, in so great an Affair of Life, they should consider the Genius and Abilities of their Children, more than their own Inclinations. It is the great Advantage of a trading Nation, that there are very few in it so dull and heavy, who may not be placed in Stations of Life which may give them an Opportunity of making their Fortunes. A well-regulated Commerce is not, like Law, Physick or Divinity, to be overstocked with Hands; but, on the contrary, flourishes by Multitudes, and gives Employment to all its Professors. Fleets of Merchantmen are so many Squadrons of floating Shops, that vend our Wares and Manufactures in all the Markets of the World, and find out Chapmen under both the Tropicks. C.
