"How much talk there is about religion! Giles [Footnote: Rev. Henry Giles.] I like the best, for he seems, like myself, to have no settled views, and to be religious only in feeling. He says he has no piety, but a great sense of infinity. "Yesterday I had a Shaker visitor, and to-day a Catholic; and the more I see and hear, the less do I care about church doctrines. The Catholic, a priest, I have known as an Atheneum visitor for some time. He talked to-day, on my asking him some questions, and talked better than I expected. He is plainly full of intelligence, full of enthusiasm for his religion, and, I suspect, full of bigotry. I do not believe he will die a Catholic priest. A young man of his temperament must find it hard to live without family ties, and I shall expect to hear, if I ever hear of him again, that some good little Irish girl has made him forget his vows. "My visitors, in other respects, have been of the average sort. Four women have been delighted to make my acquaintance--three men have thought themselves in the presence of a superior being; one offered me twenty-five cents because I reached him the key of the museum. One woman has opened a correspondence with me, and several have told me that they knew friends of mine; two have spoken of me in small letters to small newspapers; one said he didn't see me, and one said he did! I have become hardened to all; neither compliment nor quarter-dollar rouses any emotion. My fit of humility, which has troubled me all summer, is shaken, however, by the first cool breeze of autumn and the first walk taken without perspiration. "Sept. 22, 1854. On the evening of the 18th, while 'sweeping,' there came into the field the two nebulae in Ursa Major, which I have known for many a year, but which to my surprise now appeared to be three. The upper one, as seen from an inverting telescope, appeared double-headed, like one near the Dolphin, but much more decided than that, the space between the two heads being very plainly discernible and subtending a decided angle. The bright part of this object was clearly the old nebula--but what was the appendage? Had the nebula suddenly changed? Was it a comet, or was it merely a very fine night? Father decided at once for the comet; I hesitated, with my usual cowardice, and forbade his giving it a notice in the newspaper. "I watched it from 8.30 to 11.30 almost without cessation, and was quite sure at 11.30 that its position had changed with regard to the neighboring stars. I counted its distance from the known nebula several times, but the whole affair was difficult, for there were flying clouds, and sometimes the nebula and comet were too indistinct to be definitely seen. "The 19th was cloudy and the 20th the same, with the variety of occasional breaks, through which I saw the nebula, but not the comet.
