We went together this morning to the house of the Curator of the Gray collection of Engravings, which is solemnly to unfold its glories to me to-morrow. He is a most serious stately German gentleman, Mr. Thies by name, fully sensible of the deep vital importance of his treasures and evidently thinking a visit to them a great affair--to _me_. Had I known how great, how tremendous and formal, I hardly think I should have ventured to call. Tom Ward pays me a visit almost every evening. Poor Tom seems a-cold too. His deafness keeps him from making acquaintances. Professor Eliot, at the School, is a fine fellow, I suspect; a man who if he resolves to do a thing won't be prevented. I find analysis very interesting _so far_! The Library has a reading-room, where they take all the magazines; so I shan't want for the Rev. des 2 M. I remain with unalterable sentiments of devotion ever, my dear H., your Big Brother Bill. This record of further impressions closely and copiously followed. Your letter this morning was such a godsend that I hasten to respond a line or two, though I have no business to--for I have a fearful lesson to-morrow and am going to Boston to-night to hear Agassiz lecture (12 lectures on "Methods in Nat. Hist."), so that I will only tell you that I am very well and my spirits just getting good. Miss Upham's table is much pleasanter than the other. Professor F. J. Child is a great joker--he's a little flaxen-headed boy of about 40. There is a nice old lady boarder, another man of about 50, of aristocratic bearing, who interests me much, and 3 intelligent students. At the other table was no conversation at all; the fellows had that American solemnity, called each other Sir, etc. I cannot tell you, dearest Mother, how your account of your Sunday dinner and of your feelings thereat brought tears to my eyes. Give Father my ardent love and cover with kisses the round fair face of the most kiss-worthy Alice. Then kiss the Aunt till you get tired, and get all the rest of them to kiss _you_ till you cry hold enough!
