In truth, though I have felt and can still feel the attraction of foreign travel in all its strength, I would counsel you to stop at home, and as Goethe says, find your America here. There are plenty of people who can observe and whose places, if they are expended by fever or shipwreck, can be well enough filled up. But there are very few who can grapple with the higher problems of science as you have done and are doing, and we cannot afford to lose you. It is the organisation of knowledge rather than its increase which is wanted just now. And I think you can help in this great undertaking better in Germany than in New Zealand. Darwin has been very ill for more than a year past, so ill, in fact, that his recovery was at one time doubtful. But he contrives to work in spite of fate, and I hope that before long we shall have a new book from him. By way of consolation I sent him an extract from your letter touching the progress of his views. I am glad that you did not think my critique of Kolliker too severe. He is an old friend of mine, and I desired to be as gentle as possible, while performing the unpleasant duty of showing how thoroughly he had misunderstood the question. I shall look with great interest for your promised book. Lately I have been busy with Ethnological questions, and I fear I shall not altogether please your able friend Professor Schleicher in some remarks I have had to make upon the supposed value of philological evidence. May we hope to see you at the meeting of the British Association at Birmingham? It would give many, and especially myself, much pleasure to become personally acquainted with you. Ever yours faithfully, T.H. Huxley. The Royal School of Mines, Jermyn Street, June 1, 1865. My dear Darwin, Your MS. [of "Pangenesis"] reached me safely last evening. I could not refrain from glancing over it on the spot, and I perceive I shall have to put on my sharpest spectacles and best considering cap. I shall not write till I have thought well on the whole subject. Ever yours, T.H. Huxley. Jermyn Street, July 16, 1865. My dear Darwin, I have just counted the pages of your MS. to see that they are all right, and packed it up to send you by post, registered, so I hope it will reach you safely. I should have sent it yesterday, but people came in and bothered me about post time. I did not at all mean by what I said to stop you from publishing your views, and I really should not like to take that responsibility. Somebody rummaging among your papers half a century hence will find "Pangenesis" and say, "See this wonderful anticipation of our modern theories, and that stupid ass Huxley preventing his publishing them." And then the Carlyleans of that day will make me a text for holding forth upon the difference between mere vulpine sharpness and genius.
