Dear Sir

I send you herewith my article on Ice-erosion of Lake Basins² which you kindly promised to look over. I shall be glad if you will point out any errors of fact or any general statements which may want qualifying, which your extensive knowledge of the subject will no-doubt enable you to do. To myself, the converging arguments seem absolutely conclusive; especially [2] when combined with the new argument (as I think it is) in Section 5. I was much pleased when the "outline" argument, illustrated by the sketch maps, occurred to me, as it seems to clench the preceeding arguments. I shall be glad to hear if you think it sound, & whether it has previously occurred to any other writer.

The first article— on Ice "Erratics and Ice. Sheets"³ will [3] appear in the November "Fortnightly Review", this one not till December. The first merely attempts to give a popular sketch of the main features & proofs of glaciation, & its extent as proved by Erratics, so as to prepare the way for the full discussion of the Lake Theory.

Yours very truly | Alfred R. Wallace. [signature]

P.S. Your cousin Dr. C. Geikie,⁴ is near us at Bournemouth & often comes & enlivens us with his geniality & humour. A.R.W.
