Note 199 — Chapter V
Reading edition
"To the Malacodermous division belongs the remarkable genus Lampyris, which contains the insects commonly called glow-worms. The substance from which the luminous property results has been the subject of frequent experiment and observation. It is obviously under the control of the animal, which, when approached, may frequently be observed to diminish or put out its light. The only species with which we are acquainted in British America is Lampyris corusca. It occurs in Canada, and has been taken at least as far north as latitude 54°. It was originally described by Simmons as a native of Finland and Russia, on the authority of Uddman, but has not since been found there."—Murray, vol. iii., p. 277.
"We saw numerous yellow butterflies, very like a British species. Sometimes forty of them clustering on a small spot resembled a plot of primroses, and as they rose altogether, and flew off slowly on every side, it was like the play of a beautiful fountain."—Lyell's America, vol. i., p. 25.
