B. Editing and re-writing lectures on Elementary Physiology, just delivered here and reported as I went along. ([Delivered on Friday evenings from April to June at Jermyn Street, and reported in the "Medical Times." They formed the basis of his well-known little book on "Elementary Physiology," published 1866. He writes on April 22:--] "Macmillan has just been with me, and I am let in for a school book on physiology based on these lectures of mine. Money arrangements not quite fixed yet, but he is a good fellow, and will not do me unnecessarily.") C. Thinking of my course of twenty-four lectures on the Mammalia at the College of Surgeons in next spring, and making investigations bearing on the same. D. Thinking of and working at a "Manual of Comparative Anatomy" (may it be d--d); which I have had in hand these seven years. E. Getting heaps of remains of new Labyrinthodonts from the Glasgow coalfield, which have to be described. F. Working at a memoir on Glyptodon based on a new and almost entire specimen at the College of Surgeons. G. Preparing a new decade upon Fossil fishes for this place. H. Knowing that I ought to have written long ago a description of a most interesting lot of Indian fossils sent to me by Oldham. I. Being blown up by Hooker for doing nothing for the "Natural History Review." K. Being bothered by sundry editors just to write articles "which you know you can knock off in a moment." L. Consciousness of having left unwritten letters which ought to have been written long ago, especially to C. Darwin. M. General worry and botheration. Ten or twelve people taking up my time all day about their own affairs. N. O. P. Q. R. S. T. U. V. W. X. Y. Z. Societies. Clubs. Dinners, evening parties, and all the apparatus for wasting time called "Society." Colensoism and botheration about Moses...Finally pestered to death in public and private because I am supposed to be what they call a "Darwinian." If that is not enough, I could exhaust the Greek alphabet for heads in addition. I am glad to hear that Wyman thinks well of my book, as he is very competent to judge. I hear it is republished in America, but I suppose I shall get nothing out of it. [In this expectation, however, he was agreeably disappointed by the action of D. Appleton and Company. An undated letter to Kingsley, who had suggested that he should write an article on Prayer, belongs probably to the autumn of 1863:--] I should like very much to write such an article as you suggest, but I am very doubtful about undertaking it for "Fraser." Anything I could say would go to the root of praying altogether, for inasmuch as the whole universe is governed, so far as I can see, in the same way, and the moral world is as much governed by laws as the physical--whatever militates against asking for one sort of blessing seems to me to tell with the same force against asking for any other.
