As for myself, I have sent the MS.

of my book on domestic animals, etc., to the printers.

It turns out to be much too large; it will not be published, I suppose, until next November.

I find that we have discussed several of the same subjects, and I think we agree on most points fairly well.
I have lately heard several times from Fritz Muller, but he seems now chiefly to be working on plants.

I often think of your visit to this house, which I enjoyed extremely, and it will ever be to me a real pleasure to remember our acquaintance.
