[197] Messrs. Murie and Mivart in their "Anatomy of the Lemuroidea" ("Transact. Zoolog. Soc." vol. vii. 1869, p. 96-98) say, "some muscles are so irregular in their distribution that they cannot be well cla.s.sed in any of the above groups." These muscles differ even on the opposite sides of the same individual.
[198] "Quarterly Review," April, 1869, p. 392. This subject is more fully discussed in Mr. Wallace"s "Contributions to the Theory of Natural Selection," 1870, in which all the essays referred to in this work are republished. The "Essay on Man"
has been ably criticised by Prof. Claparede, one of the most distinguished zoologists in Europe, in an article published in the "Bibliotheque Universelle," June, 1870. The remark quoted in my text will surprise every one who has read Mr. Wallace"s celebrated paper on "The Origin of Human Races deduced from the Theory of Natural Selection," originally published in the "Anthropological Review," May, 1864, p. clviii. I cannot here resist quoting a most just remark by Sir J. Lubbock ("Prehistoric Times," 1865, p. 479) in reference to this paper, namely, that Mr. Wallace, "with characteristic unselfishness, ascribes it (_i.e._ the idea of natural selection) unreservedly to Mr. Darwin, although, as is well known, he struck out the idea independently, and published it, though not with the same elaboration, at the same time."
[199] Quoted by Mr. Lawson Tait in his "Law of Natural Selection,"-"Dublin Quarterly Journal of Medical Science,"
Feb. 1869. Dr. Keller is likewise quoted to the same effect.

Dr. Jarrold ("Anthropologia," 1808, p. 115, 116) adduces from Camper and from his own observations, cases of the modification of the skull from the head being fixed in an unnatural position. He believes that certain trades, such as that of a shoemaker, by causing the head to be habitually held forward, makes the forehead more rounded and prominent.

Prof. P. Gervais ("Hist. Nat. des Mammiferes," tom. i. 1854, p.
28), however, states that in the Gorilla the hair is thinner on the back, where it is partly rubbed off, than on the lower surface.

It has also been discussed in the "Q. Journal of Science," 1869, p. 152, and by Mr. Lawson Tait in the "Dublin Q. Journal of Medical Science," Feb. 1869, and by Mr. E. Ray Lankester in his "Comparative Longevity," 1870, p. 128. Similar views appeared previously in the "Australasian," July 13, 1867.
I have borrowed ideas from several of these writers.
