But now, and for some time to come, I must be thinking of quite different matters.

I mean to continue this essay in the January number--for which my MSS.

must be ready about the 1st of November.
I have not yet attempted to count them up; but of course I am prepared to believe that fully three-fourths of our species common to Europe will [be] found to range northward to the Arctic regions.

I merely meant that I had in mind a number that do not; I think the number will not be very small; and I thought you were under the impression that very few absolutely did not so extend northwards.

The most striking case I know is that of Convallaria majalis, in the mountains [of] Virginia and North Carolina, and not northward.
