Wabours of Pierre Lyornet, the Entomologrsi. ———_—_++____— NLY think of an entomologist celebrated for having devoted several years to the investigation of a single insect! Surely he deserves to be ranked among the en- thusiasts of science. Pierre Lyonnet, ahke dis- tinguished as a naturalist, an anatomist, and an engraver, was born on the 21st July 1707, at Maestricht. His family came originally from Lorraine, having been driven from their native country by religious persecution. Huis father, who was pastor of the French Church at Keusden, destined his son for the same sacred calling, and educated him with that view. Having an extra- ordinary aptitude for acquiring languages, he made himself master, at an early age, of Latin, Greek, Hebrew, French, Italian, Spanish, and English, with all which he was almost equally conversant. At the same time he studied the exact sciences and attained considerable proficiency in drawing wnd sculpture.
