[37] So with insects, the larvæ reproduce lost limbs, but, except in one order, the mature insect has no such power. But the Myriapoda, which apparently represent the larvæ of true insects, have, as Newport has shown, this power until their last moult. See an excellent discussion on this whole subject by Dr. Carpenter in his 'Princ. Comp. Phys.,' 1854, p. 479.
