ing from his own pen ; but " Knick-knacks 

 from an Editor's Table," published in 1852, 

 was altogether his own, and bubbled over 

 with humor. In 1855 the principal contrib- 

 utors to the Knickerbocker furnished each an 

 article and their portraits to an elegant volume 

 called " The Knickerbocker Gallery," which, 

 supplemented by some other aid, had a sufficient 

 sale to purchase from its net profits a residence 

 for him at Piermont, N. Y., where he resided 

 till his death. After the Knickerbocker was 

 iriven up, Mr. Clark held for some years a posi- 

 tion in the New York Custom-House. He 

 continued to contribute to periodical literature 

 till a tew weeks before his death, but of late 

 not with his earlier ability and success. 



CLAUK, WILLIAM W., an American scientist; 

 born in Livingston County, N. Y., in 1824; 

 died in Rochester, N. Y., August 10, 1873. He 

 entered the New York State Normal School in 

 1844, very thoroughly prepared in the physical 

 sciences, and capable even then of giving in- 

 struction in them. He graduated in 1845, 

 and was immediately appointed Professor of 

 Chemistry in the Normal School, and in 1847 



Professor of the Natural Sciences. In 1849 

 he assisted in the State geological survey, and 

 in 1852 was associated with the late Prof. 

 Ebenezer Emmons in making a similar survey 

 in North Carolina. He was the author of the 

 law fixing the standard of weights and meas- 

 ures in the State, and had taken a great in- 

 terest in the introduction of the metrical 

 system. For several years he was occupied in 

 geological and geodetic surveys, and did not, 

 we believe, engage in teaching after resigning 

 his position in connection with the State Nor- 

 mal School. Of late he had been a great 

 sufferer from ill-health, and had resided for 

 some years at Honeoye Falls, whence he 

 removed to Rochester not long before his 

 death.
