I shall work the British flora with three separate Floras; and I intend dividing the varieties into two classes, as Asa Gray and Henslow give the materials, and, further, A.Gray and H.C.
Watson have marked for me the forms, which they consider real species, but yet are very close to others; and it will be curious to compare results.

If it will all hold good it is very important for me; for it explains, as I think, all classification, i.e.the quasi-branching and sub-branching of forms, as if from one root, big genera increasing and splitting up, etc., as you will perceive.

But then comes in, also, what I call a principle of divergence, which I think I can explain, but which is too long, and perhaps you would not care to hear.

As you have been on this subject, you might like to hear what very little is complete (for my schoolmaster has had three weeks' holidays)--only three cases as yet, I see.
