You will be very glad to know that I am exceedingly comfortable here. My cabin has now got into tolerable order, and what with my books--which are, I am happy to say, not a few--my gay curtain and the spicy oilcloth which will be down on the floor, looks most respectable. Furthermore, although it is an unquestionably dull day I have sufficient light to write here, without the least trouble, to read, or even if necessary, to use my microscope. I went to see a friend of mine on board the "Recruit" the other day, and truly I hugged myself when I compared my position with his. The berth where he and seven others eat their daily bread is hardly bigger than my cabin, except in height--and, of course, he has to sleep in a hammock. My friend is rather an eccentric character, and, being missed in the ship, was discovered the other day reading in the main-top--the only place, as he said, sufficiently retired for study. And this is really no exaggeration. If I had no cabin I should take to drinking in a month.

Here he obtained from Professor Edward Forbes one of his living specimens of Amphioxus lanceolatus, and made an examination of its blood. The result was a short paper read at the following meeting of the Association, which showed that in the composition of its blood this lowly vertebrate approached very near the invertebrates.
