Praise of Herbert Spencer's First Principles .
5, Westbourne Grove Terrace, W.
My dear Mr. Darwin
Many thanks for the third Ed. of the ``Origin'' which I found here on my return from Devonshire on Saturday.
I have not had time yet to read more than the ``Historical Sketch'' which is very interesting & shews that the time had quite come for your book.
I am now reading Herbert Spencer's First Principles, which seems to me a truly great work, which goes to the root of everything.
I hope you will be well enough to come to Cambridge.
I remain | My dear Mr. Darwin | Yours very faithfully | Alfred R. Wallace
