I have been greatly interested also in your Memoir on Pentastomum. There can be no difficulty about getting a notice of it in our journals, and, indeed, I will see to it myself. Pray do me the favour to let me know whenever I can serve you in this or other ways.
I shall do myself the pleasure of forwarding to you immediately, through the booksellers, a lecture of mine on the Theory of the Vertebrate Skull, which is just published, and also a little paper on the development of the tail in fishes.
I am sorry to say that I have but little time for working at these matters now, as my position at the School of Mines obliges me to confine myself more and more to Paleontology.
However, I keep to the anatomical side of that sort of work, and so, now and then, I hope to emerge from amidst the fossils with a bit of recent anatomy.
Just at present, by the way, I am giving my disposable hours to the completion of a monograph on the Calycophoridae and Physophoridae observed during my voyage. The book ought to have been published eight years ago. But for three years I could get no money from the Government, and in the meanwhile you and Kolliker, Gegenbaur and Vogt, went to the shores of the Mediterranean and made sad havoc with my novelties. Then came occupations consequent on my appointment to the chair I now hold; and it was only last autumn that I had leisure to take up the subject again.
However, the plates, which I hope you will see in a few months have, with two exceptions, been engraved five years.
Pray make my remembrances to Dr. Eckhard. I was sorry not to have seen him again in London.
Ever, my dear Sir, very faithfully yours,
T.H. Huxley.
Professor Leuckart.
