On the cross-breeding of two races of moth Acidalia virgularia

The general interest which has been aroused of recent years by the various researches which have been undertaken in investigation of the working of Mendel’s Law of Heredity, and the adaptability of the Order Lepidoptera to such investigation, have led us not only to reconsider the results of some earlier and undirected experiments in moth-breeding, but also to seek out some peculiarly suitable species in order to take in hand a more exhaustive course of study along the lines most likely to yield further results in elucidation of Mendelism.Résumé of some Previous Rearing Experiments . Perhaps a brief reference should be made to our previously recorded attempts at pedigree-breeding.
