The landlady was a Quaker, with half-a-dozen grown-up daughters. Our fellow-lodgers consisted of the Rev. A.E. Lawrence, Assistant-Secretary of the American Home Missionary Society (who had a few months before become the landlady's son-in-law); the Rev. Mr. Martyn, and his wife, a woman of fine talents, and editor of "The Ladies' Wreath;" the Rev. Mr. Brace, an editor in the employ of the Tract Society; Mr. Daniel Breed, M.D., a Quaker, and principal of a private academy for young gentlemen (also the landlady's son-in-law); Mr. Oliver Johnson, a sub-editor of the _Daily Tribune_, and a well-known Abolitionist; and Mr. Lockwood, a retired grocer,--who, having gained a small independence, was thus enjoying it with his youthful wife and child in lodgings.

In the evening of the 17th I went to the Broadway Tabernacle, to hear a lecture on Astronomy from Professor Mitchell of Cincinnati, no ordinary man. Although the admission fee was half-a-dollar, upwards of a thousand persons were present. Without either diagrams or notes, the accomplished lecturer kept his audience in breathless attention for upwards of an hour. He seemed to be a devout, unassuming man, and threw a flood of light on every subject he touched. His theme was the recent discovery of the Leverrier planet; and perhaps you will not be displeased if I give you a summary of his lucid observations. In observing how the fluctuations of the planet Herschel had ultimately led to this discovery, he said:
