The Hon. and Rev. W. Herbert, afterwards Dean of Manchester, in the fourth volume of the ‹Horticultural Transactions›, 1822, and in his work on the ‹Amaryllidaceæ› (1837, p. 19, 339), declares that “horticultural experiments have established, beyond the possibility of refutation, that botanical species are only a higher and more permanent class of varieties”. He extends the same view to animals. The Dean believes that single species of each genus were created in an originally highly plastic condition, and that these have produced, chiefly by intercrossing, but likewise by variation, all our existing species.

In 1826 professor Grant, in the concluding paragraph in his well-known paper (‹Edinburgh Philosophical Journal›, vol. xiv. p. 283) on the Spongilla, clearly declares his belief that species are descended from other species, and that they become improved in the course of modification. This same view was given in his 55th Lecture, published in the ‹Lancet› in 1834.
