[ Since the publication of the essay just referred to, Mr. Spencer has written another, on “Morals and Moral Sentiments,” in the ‘Fortnightly Review,’ April 1, 1871, p. 426. He has, also, now published his final conclusions in vol. ii. of the second edit. of the ‘Principles of Psychology,’ 1872, p. 539. I may state, in order that I may not be accused of trespassing on Mr. Spencer’s domain, that I announced in my ‘Descent of Man,’ that I had then written a part of the present volume: my first MS. notes on the subject of expression bear the date of the year 1838.]

[ Professor Owen expressly states (Proc. Zoolog. Soc. 1830, p. 28) that this is the case with respect to the Orang, and specifies all the more important muscles which are well known to serve with man for the expression of his feelings. See, also, a description of several of the facial muscles in the Chimpanzee, by Prof. Macalister, in ‘Annals and Magazine of Natural History,’ vol. vii. May, 1871, p. 342.]
