    Summary Add

    Introduces Ernst Haeckel.

    Lyell sent same chapters to CD, who thinks them very good but is not convinced that changes of land and water will do all he thinks.




My dear Hooker

The Bearer of this is Prof. Ernst Häckel, a first-rate Zoologist, who wishes much to know you, so I could not refuse a note of introduction, but I hope he will not take up very much of your time.—

Your splendid present of trees & conifers has arrived all safe & Emma is very much obliged to you.—

I am delighted to hear about the Government & your Fathers Herbarium & Books; though £7000 is a good big sum, I suppose it is a mere fraction of what your Father must have spent on them.—

Lyell sent me the same chapters to read: they seemed to me very good indeed, not that I am convinced that change of land & water will do all that he thinks.—

I am tired so good night.

Ever Yours | C. Darwin
