I meant to have written to you yesterday to say how glad I shall be to read whatever you like to send me.
I have to lecture at the Royal Institution this week, but after Friday, my time will be more at my own disposal than usual; and as always I shall be most particularly glad to be of any use to you.
Any glimmer of light on the question you speak of is of the utmost importance, and I shall be immensely interested in learning your views. And of course I need not add I will do my best to upset them. That is the nature of the beast.
I had a letter from one of the ablest of the younger zoologists of
Germany, Haeckel, the other day, in which this passage occurs:—
"The Darwinian Theory, the establishment and development of which is the object [of] all my scientific labours, has gained ground immensely in Germany (where it was at first so misunderstood) during the last two years, and I entertain no doubt that it will before long be everywhere victorious." And he adds that I dealt far too mildly with Kolliker.
With kindest remembrances to Mrs. Darwin and your family.
Ever yours faithfully,
T.H. Huxley.
[This year, as is seen from the foregoing, he was again in direct communication with Professor Ernst Haeckel of Jena, the earliest and strongest champion of Darwinian ideas in Germany. The latter wished to enlarge his observations by joining some English scientific expedition, if any such were in preparation, but was dissuaded by the following reply. The expected book of Darwin's was the "Pangenesis," and this is also referred to in the three succeeding letters to Darwin himself.]
