[37] So with insects, the larvae reproduce lost limbs, but, except in one
order, the mature insect has no such power. But the Myriapoda, which
apparently represent the larvae 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.
