	John Playfair
		PLAYFAIR, JOHN, an eminent natural philosopher and mathematician, was the eldest son of James Playfair, minister of Benvie, in Forfarshire, where he was born on the 10th of March, 1748.
		In 1779, Playfair’s first scientific effort was given to the public, in "An Essay on the Arithmetic of Impossible Quantities," published in the sixty-eighth volume of the Philosophical Transactions.
		In connexion with this it is to be held in mind, that Playfair was essentially a reasoner, and that he was more celebrated for separating the true from the false in the writings of others, or for establishing and applying truths accidentally stumbled upon by others, than for extensive discoveries of his own.
