DEAREST FANNY,-- ...Beautiful as the spring is here, the words you so often let drop about American weather make me homesick for that article. It is blasphemous, however, to pine for anything when one is in Edinburgh in May, and takes an open drive every afternoon in the surrounding country by way of a constitutional. The green is of the vividest, splendid trees and acres, and the air itself an _object_, holding watery vapor, tenuous smoke, and ancient sunshine in solution, so as to yield the most exquisite minglings and gradations of silvery brown and blue and pearly gray. As for the city, its vistas are magnificent. We are _comblés_ with civilities, which Harry and Alice are to a certain extent enjoying, though I have to hang back and spend much of the time between my lectures in bed, to rest off the aortic distress which that operation gives. I call it aortic because it feels like that, but I can get no information from the Drs., so I won't swear I'm right. My heart, under the influence of that magical juice, tincture of digitalis,--only 6 drops daily,--is performing _beautifully_ and gives no trouble at all. The audiences grow instead of dwindling, and in spite of rain, being about 300 and just crowding the room. They sit as still as death and then applaud magnificently, so I am sure the lectures are a success. Previous Gifford lectures have had audiences beginning with 60 and dwindling to 15. In an hour and a half (I write this in bed) I shall be beginning the fifth lecture, which will, when finished, put me half way through the arduous job. I know you will relish these details, which please pass on to Jim P. I would send you the reports in the "Scotsman," but they distort so much by their sham continuity with vast omission (the reporters get my MS.), that the result is caricature. Edinburgh is _spiritually_ much like Boston, only stronger and with more temperament in the people. But we're all growing into much of a sameness everywhere. I have dined out once--an almost fatal experiment! I was introduced to Lord Somebody: "How often do you lecture?"--"Twice a week."--"What do you do between?--play golf?" Another invitation: "Come at 6--the dinner at 7.30--and we can walk or play bowls till dinner so as not to fatigue you"--I having pleaded my delicacy of constitution.
