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.

I have been informed of this fact through the Rev. W. D. Fox, on the excellent authority of Mr. Wilmot: see, also, remarks on this subject in an original article in the 'Quarterly Review,' 1849, p. 395.

Dureau de la Malle, in 'Comptes Rendus,' tom. xli., 1855, p. 807. From the statements above given, the author concludes that the wild pigs of Louisiana are not descended from the European Sus scrofa.

77

Capt. W. Allen, in his 'Expedition to the Niger,' states that fowls have run wild on the island of Annobon, and have become modified in form and voice. The account is so meagre and vague that it did not appear to me worth copying; but I now find that Dureau de la Malle ('Comptes Rendus,' tom. xli., 1855, p. 690) advances this as a good instance of reversion to the primitive stock, and as confirmatory of a still more vague statement in classical times by Varro.

Quoted by Mr. Sedgwick in 'Med. – Chirurg. Review,' April, 1861, p. 485. Dr. H. Dobell, in 'Med. – Chirurg. Transactions,' vol. xlvi., gives an analogous case, in which, in a large family, fingers with thickened joints were transmitted to several members during five generations; but when the blemish once disappeared it never reappeared.
