2 .-- I worked all yesterday evening in thinking, and have written the paper sent by this post this morning.

Not one sentence would do, but it is the sort of rough sketch which I should have drawn out if I had had to do it.

God knows whether it will at all aid you.

It is miserably written, with horridly bad metaphors, probably horrid bad grammar.

It is my deliberate impression, such as I should have written to any friend who had asked me what I thought of Lyell's merits.
