I got a note from Hillebrand saying Schiff would gladly let me work in his laboratory if I liked. I suppose I ought if I can, but I hanker after home even at the price of a February voyage, and I hate to spend so much money here on my mere gizzard and cheeks.--There, my sweet sister, I hope that is a sufficiently spirited epistle for 10.30 P.M. When, oh, when, will you write me another like the solitary one I got from you in Florence? Seven weeks and one letter! C'est très caractéristique de vous! I wrote two days ago to Annie Ashburner. Tell the adorable Sara Sedgwick [Mrs. W. E. Darwin] that I can't possibly refrain much longer--in spite of my just resentment--from writing to her. Love to all.... Your W. J. * * * * * After his return his college duties proved both absorbing and stimulating. Beginning, as the reader has seen, as an instructor in the Department of Natural History, charged with teaching the comparative anatomy and physiology of vertebrates, he added a course on physiological psychology in 1876, and organized the beginnings of the psychological laboratory.[55] The next year this course was transferred to the Department of Philosophy and given under the title "Psychology." He contributed numerous reviews of scientific and philosophic literature, along with a few anonymous articles, to the columns of the "Atlantic Monthly" and the "Nation," and in 1878 appeared in the "Journal of Speculative Philosophy" and the "Critique Philosophique," with three important papers entitled "Spencer's Definition of Mind as Correspondence," "Brute and Human Intellect," and "Quelques Considérations sur la Méthode Subjective." Meanwhile his correspondence diminished to its minimum. When his brother Henry also came home to America in 1874, it ceased almost entirely. It did not begin to flow freely again, at least so far as letters are now recoverable, until after 1878. _To Henry James._ CAMBRIDGE, _June 25, 1874_.
