SNOW, William Dunham, lawyer, born in Webster, Worcester County, Massachusetts, 2 February, 1832. He settled in Rochester, New York, where he published "The Tribune" in 1852-'4. Afterward he removed to Arkansas, was a member of the Constitutional convention in 1863 that made Arkansas a free state, and was elected United States senator in 1864 under the proclamation of President Johnson, but was not admitted to a seat. He was largely instrumental in raising a brigade of Arkansas troops for the United States army in 1865, and declined the commission of brigadier-general. Since his graduation at Columbia law-school in 1876 he has practised in New York city and in the Federal courts. He has invented a successful carburettor, a gas-regulator, a thermostatic apparatus for the maintenance of equal heat for furnaces and steam apparatus, and a system for fac-simile telegraphy. Mr. Snow is the author of several anti-slavery poems, and has contributed to magazines.
