Dear Sir,

I thank you most sincerely for sending me your Address and the Geological Report. (Address to the 'Philosophical Institute of Canterbury (N.Z.).' The "Report" is given in "The New Zealand Government Gazette, Province of Canterbury", October 1862.) I have seldom in my life read anything more spirited and interesting than your address. The progress of your colony makes one proud, and it is really admirable to see a scientific institution founded in so young a nation. I thank you for the very honourable notice of my 'Origin of Species.' You will easily believe how much I have been interested by your striking facts on the old glacial period, and I suppose the world might be searched in vain for so grand a display of terraces. You have, indeed, a noble field for scientific research and discovery. I have been extremely much interested by what you say about the tracks of supposed [living] mammalia. Might I ask, if you succeed in discovering what the creatures are, you would have the great kindness to inform me? Perhaps they may turn out something like the Solenhofen bird creature, with its long tail and fingers, with claws to its wings! I may mention that in South America, in completely uninhabited regions, I found spring rat-traps, baited with CHEESE, were very successful in catching the smaller mammals. I would venture to suggest to you to urge on some of the capable members of your institution to observe annually the rate and manner of spreading of European weeds and insects, and especially to observe WHAT NATIVE PLANTS MOST FAIL; this latter point has never been attended to. Do the introduced hive-bees replace any other insect? etc. All such points are, in my opinion, great desiderata in science. What an interesting discovery that of the remains of prehistoric man!

Believe me, dear Sir, With the most cordial respect and thanks, Yours very faithfully, CHARLES DARWIN.

CHARLES DARWIN TO CAMILLE DARESTE. (Professor Dareste is a well-known worker in Animal Teratology. He was in 1863 living at Lille, but has since then been called to Paris. My father took a special interest in Dareste's work on the production of monsters, as bearing on the causes of variation.) Down, February 16 [1863].

Dear and respected Sir,

I thank you sincerely for your letter and your pamphlet. I had heard (I think in one of M. Quatrefages' books) of your work, and was most anxious to read it, but did not know where to find it. You could not have made me a more valuable present. I have only just returned home, and have not yet read your work; when I do if I wish to ask any questions I will venture to trouble you. Your approbation of my book on Species has gratified me extremely. Several naturalists in England, North America, and Germany, have declared that their opinions on the subject have in some degree been modified, but as far as I know, my book has produced no effect whatever in France, and this makes me the more gratified by your very kind expression of approbation. Pray believe me, dear Sir, with much respect,

Yours faithfully and obliged, CH. DARWIN.

CHARLES DARWIN TO J.D. HOOKER. Down, February 24 [1863].

My dear Hooker,

I am astonished at your note, I have not seen the "Athenaeum" (In the 'Antiquity of Man,' first edition, page 480, Lyell criticised somewhat severely Owen's account of the difference between the Human and Simian brains. The number of the "Athenaeum" here referred to (1863, page 262) contains a reply by Professor Owen to Lyell's strictures. The surprise expressed by my father was at the revival of a controversy which every one believed to be closed. Prof. Huxley ("Medical Times", October 25, 1862, quoted in 'Man's Place in Nature,' page 117) spoke of the "two years during which this preposterous controversy has dragged its weary length." And this no doubt expressed a very general feeling.) but I have sent for it, and may get it to-morrow; and will then say what I think.
