IN “Vestiges of Creation,” ninth edition, 1851, p. 113, it is stated that two independent investigators caused the production of “living insects” (Acarus crossii) by the prolonged action of a voltaic battery upon certain chemical solutions. The description is most matter-of-fact. The second experimenter seems to have sterilised his apparatus and solutions before use; yet it is said that the insects “were sometimes observed to go back to the fluid to feed, and occasionally they devoured each other.” In Note 54 it is also stated that “after they have escaped from the solution they live in the neighbourhood, and readily breed.”
