Note 324 — Chapter VII

See a paper read before the Royal Soc. in 1813, and published in his Essays in 1818. I have given an account of Dr. Wells’ views in the Historical Sketch (p. xvi) to my ‘Origin of Species.’ Various cases of colour correlated with constitutional peculiarities are given in my 'Variation of Animals under Domestication,’ vol. ii. p. 227, 335.
