I have just finished with very great interest "Man's Place." (164/1. "Evidence as to Man's Place in Nature," 1863 (preface dated January 1863).) I never fail to admire the clearness and condensed vigour of your style, as one calls it, but really of your thought. I have no criticisms; nor is it likely that I could have. But I think you could have added some interesting matter on the character or disposition of the young ourangs which have been kept in France and England. I should have thought you might have enlarged a little on the later embryological changes in man and on his rudimentary structure, tail as compared with tail of higher monkeys, intermaxillary bone, false ribs, and I daresay other points, such as muscles of ears, etc., etc. I was very much struck with admiration at the opening pages of Part II. (and oh! what a delicious sneer, as good as a dessert, at page 106) (164/2. Huxley, op. cit., page 106. After saying that "there is but one hypothesis regarding the origin of species of animals in general which has any scientific existence--that propounded by Mr. Darwin," and after a few words on Lamarck, he goes on: "And though I have heard of the announcement of a formula touching 'the ordained continuous becoming of organic forms,' it is obvious that it is the first duty of a hypothesis to be intelligible, and that a qua-qua-versal proposition of this kind, which may be read backwards or forwards, or sideways, with exactly the same amount of significance, does not really exist, though it may seem to do so." The "formula" in question is Owen's.): but my admiration is unbounded at pages 109 to 112. I declare I never in my life read anything grander. Bacon himself could not have charged a few paragraphs with more condensed and cutting sense than you have done. It is truly grand. I regret extremely that you could not, or did not, end your book (not that I mean to say a word against the Geological History) with these pages. With a book, as with a fine day, one likes it to end with a glorious sunset. I congratulate you on its publication; but do not be disappointed if it does not sell largely: parts are highly scientific, and I have often remarked that the best books frequently do not get soon appreciated: certainly large sale is no proof of the highest merit. But I hope it may be widely distributed; and I am rejoiced to see in your note to Miss Rhadamanthus (164/3. This refers to Mr. Darwin's daughter (now Mrs. Litchfield), whom Mr. Huxley used to laugh at for the severity of her criticisms.) that a second thousand is called for of the little book. What a letter that is of Owen's in the "Athenaeum" (164/4. A letter by Owen in the "Athenaeum," February 21st, 1863, replying to strictures on his treatment of the brain question, which had appeared in Lyell's "Antiquity of Man."); how cleverly he will utterly muddle and confound the public. Indeed he quite muddled me, till I read again your "concise statement" (164/5.
