consider that I should have to look after the artists, superintend and furnish materials for the Government work, which will come out in parts, and which must appear regularly. All my Geological notes are in a very rough state; none of my fossil shells worked up; and I have much to read. I have had hopes, by giving up society and not wasting an hour, that I should finish my Geology in a year and a half, by which time the description of the higher animals by others would be completed, and my whole time would then necessarily be required to complete myself the description of the invertebrate ones. If this plan fails, as the Government work must go on, the Geology would necessarily be deferred till probably at least three years from this time. In the present state of the science, a great part of the utility of the little I have done would be lost, and all freshness and pleasure quite taken from me.
I know from experience the time required to make abstracts EVEN of my own papers for the 'Proceedings.' If I was Secretary, and had to make double abstracts of each paper, studying them before reading, and attendance would AT LEAST cost me three days (and often more) in the fortnight. There are likewise other accidental and contingent losses of time; I know Dr. Royle found the office consumed much of his time. If by merely giving up any amusement, or by working harder than I have done, I could save time, I would undertake the Secretaryship; but I appeal to you whether, with my slow manner of writing, with two works in hand, and with the certainty, if I cannot complete the Geological part within a fixed period, that its publication must be retarded for a very long time,—whether any Society whatever has any claim on me for three days' disagreeable work every fortnight. I cannot agree that it is a duty on my part, as a follower of science, as long as I devote myself to the completion of the work I have in hand, to delay that, by undertaking what may be done by any person who happens to have more spare time than I have at present. Moreover, so early in my scientific life, with so very much as I have to learn, the office, though no doubt a great honour, etc., for me, would be the more burdensome. Mr. Whewell (I know very
