Note 175 — Chapter IX
Reading edition
Compare a parallel passage in Prévost et Dumas:—"At the very first sight one will be struck with the resemblance between the forms of the very early embryos of these two classes, a resemblance so extraordinary that one cannot refuse to admit the conclusions resulting from it. The resemblance is so striking that one can defy the most experienced observer to distinguish in any way the embryos of dog or rabbit ... from those of fowls or ducks of a corresponding age."—Ann. Sci. nat., iii., p. 132, 1824.
