CHAPTER XIV. QUACKS AND IMPOSTORS.

Katerfelto was sued for its value, and was sent to prison in default of payment. And not long before his death, he was committed by the Mayor of Shrewsbury to the House of Correction in that city as a vagrant and impostor. Katerfelto mixed up with his quackery some real science, and by the aid of the solar microscope astonished the world with insect wonders. In one of his advertisements in the Morning Post, of July 1782, he says that, by its aid, the insects on the hedges will be seen larger than ever, and those insects which caused the late influenza will be seen as large as a bird; and in a drop of water the size of a pin’s head there will be seen above 50,000 insects; the same in beer, milk, vinegar, blood, flour, cheese, etc., etc., and there will be seen many surprising indifferent vegetables, and above 200 other dead objects.
