Will you not come next year, if a special invitation is sent you on the same terms?
Boott lately sent me your photograph, which (though not a very perfect one) I am well pleased to have...
But there is another question in your last letter--one about which a person can only give an impression--and my impression is that, speaking of plants of a well-known flora, what we call intermediate varieties are generally less numerous in individuals than the two states which they connect.

That this would be the case in a flora where things are put as they naturally should be, I do not much doubt; and the wider are your views about species (say, for instance, with Dr.Hooker's very latitudinarian notions) the more plainly would this appear.

But practically two things stand hugely in the way of any application of the fact or principle, if such it be.1.Our choice of what to take as the typical forms very often is not free.

We take, e.g., for one of them the particular form of which Linnaeus, say, happened to have a specimen sent him, and on which [he] established the species; and I know more than one case in which that is a rare form of a common species; the other variety will perhaps be the opposite extreme--whether the most common or not, or will be what L.or [illegible] described as a 2nd species.

Here various intermediate forms may be the most abundant.2.It is just the same thing now, in respect to specimens coming in from our new western country.
