An Anti-Slavery Group of 1850

              AN ANTI-SLAVERY GROUP OF 1850. 
WE give with this a reproduction of a very interesting picture. It is a large daguerreotype, and belongs to William Still of this city, a well-known colored citizen, formerly, for many years, active in the anti-slavery work, and intimately connected with the "underground railroad." It is a picture of twelve members of the Executive Committee of the Pennsylvania Anti-Slavery Society, and belongs to the period about 1850. It must have been taken before Eleventh month, 1851, as at that time Sarah Pugh, who is one of the group, went to Europe, not returning until Tenth month, 1853. Nor could it have been taken later than her departure for Europe, because Haworth Wetherald, another of the group, died in First month, 1853, (or possibly 1852). 
The twelve persons presented are James Mott, Lucretia Mott, Robert Purvis, Oliver Johnson, J. Miller McKim, Edward M. Davis, Abby Kimber, Mary Grew, Sarah Pugh, Haworth Wetherald, Margaret Jones, and Benjamin C. Bacon. 
The daguerreotype, neatly framed, and carefully preserved by William Still, is a beautiful example of the art, preceding photography, developed by Daguerre. The portraits are all exquisitely delicate and clear. Reproduction, however, of a daguerreotype is difficult, and our picture is not entirely satisfactory as to some of the portraits, especially Oliver Johnson and James Mott. The former's face appears narrowed, and the mouth smaller, affecting the expression. Mary Grew is also less faithful in the reproduction than we could wish. Most of the others are good, and several quite so. 

BIOGRAPHIC DETAILS. 
The recent death of Mary Grew, (on Tenth month 10, in this city), gives the picture special interest at this time. She and Robert Purvis were the only survivors of the twelve. Robert is now the last one living. Mary Grew was born in Hartford, Conn., Ninth month, 1813. Her father, Henry Grew, a Baptist minister, after moving to Boston, came in 1834 to Philadelphia, where he was for some time in charge of a church on Bank street. She had met William Lloyd Garrison in Hartford, as early as 1830, and had joined a year later the New Eng-
