Dear Sir,

I am very glad you are pleased with my paper on the Oscillation of the Land as I value your approbation very highly. I may mention however, that the Council of the Geological Soc^y declined to publish it except in a short abstract which I thought was rather shabby.

I have not seen Mr Geo. Darwin’s² memoir to which you refer — I also regret [2] having seen Mr. O Fisher’s³ book on the Physics of the earth’s crust⁴ as some of his conclusions would have been of material service to me. He thinks that altho the great internal mass of the earth may be solid yet there must be a liquid substratum to the External Crust. If this be so and this crust be floating in a liquid or viscous substratum then it is easy to see that any change of weight would give rise to an alteration in the level of flotation.

Many important facts obtained by in the course of the American Geol. surveys tend to favour this notion — while the connection between glaciation & submergence or depression is too marked to be longer ignored.

faithfully yours | Thos. F. Jamieson⁵ [signature]
