Robert Douglass, Jr., for many years, has kept a study and gallery of painting and daguerreotype in the city of Philadelphia. Mr. Douglass is an excellent artist—being a fine portrait and landscape painter, which art he practised before the discovery of daguerreotype. He is also a good lithographer, a gentleman of fine educational attainments, very clever talents, and highly esteemed in that city. Mr. Douglass has been twice to the West Indies and Europe.

J. Presley Ball is the principal daguerreotypist of Cincinnati, Ohio. Mr. Ball commenced the practice of his art about seven years ago, being then quite young, and inexperienced, as all young beginners are, laboring under many difficulties. He nevertheless, persevered, until he made a business, and established confidence in his skill; and now he does more business than any other artist in the profession in that city. His gallery, which is very large, finely skylighted, and handsomely furnished, is literally crowded from morning until evening with ladies, gentlemen, and children. He made some valuable improvements in the art, all for his own convenience. There is none more of a gentleman than J. Presley Ball. He has a brother, Mr. Thomas Ball, and a white gentleman to assist him. Few go to Cincinnati, without paying the daguerrean gallery of Mr. Ball, a visit.

The great organ of the "Liberty Party" in the United States, is now conducted by one who requires not a notice from such an obscure source—we mean Frederick Douglass, of Rochester, N.Y. His history is well known—it was written by more faithful hands than ours—it was written by himself. It stands enrolled on the reminiscences of Germany, and France, and in full length oil, in the academy of arts, and in bust of bronze or marble, in the museum of London. Mr. Douglass is also the sole owner of the printing establishment from which the paper is issued, and was promoted to this responsible position, by the power of his talents. He is a masterly letter writer, ably edits his paper, and as a speaker, and orator, let the scenes of a New York tabernacle, within two years, answer instead. Mr. Douglass is highly respected as a citizen and gentleman in Rochester.

In Syracuse, N.Y., resides George Boyer Vashon, Esq., A.M., a graduate of Oberlin Collegiate Institute, Attorney at Law, Member of the Syracuse Bar. Mr. Vashon, is a ripe scholar, an accomplished Essayist, and a chaste classic Poet; his style running very much in the strain of Byron's best efforts. He probably takes Byron as his model, and Childe Harold, as a sample, as in his youthful days, he was a fond admirer of George Gordon Noel Byron, always calling his whole name, when he named him. His Preceptor in Law, was the Honorable Walter, Judge Forward, late Controller, subsequently, Secretary of the Treasury of the United States, and recently Charge de Affaires to Denmark, now President of the Bench of the District Court of the Western District of Pennsylvania.

Mr. Vashon was admitted to the Bar of the city of New York, in the fall of 1847, to practise in all the Courts of the State. He immediately subsequently, sailed to the West Indies, from whence he returned in the fall of 1850. He has contributed considerably to a number of the respectable journals of the country.

Mrs. Ann Maria Johnson, of the School of Mrs. Tillman and Mrs. Johnson, Teachers in French Worsted Needle Work, at the Exhibition of the Mechanics' Institute in Chicago, Ill., 1846, took the First Prize, and got her Diploma, for the best embroidery in cloth. This was very flattering to those ladies, especially the Diplomast, considering the great odds they had to contend with. The ladies were very successful teachers—their classes were always large.

In Williamsburg there is T. Joiner White, M.D.; in Brooklyn Peter Ray, M.D.; and in the city of New York, also, John Degrass, M.D., all young Physicians, who have time and experience yet before them, and promise fair to be good and useful members of society.

Miss Eliza Greenfield the Black Swan, is among the most extraordinary persons of the present century. Being raised in obscurity, inured to callings far beneath her propensity, and unsuited to her taste, she had a desire to cultivate her talents, but no one to encourage her. Whenever she made the effort, she was discouraged—perhaps ridiculed; and thus discouraged, she would shrink again from her anxious task. She knew she could sing, and knew she could sing unlike any body else; knew she sung better than any whom she had heard of the popular singers, but could not tell why others could not think with, and appreciate her. In this way it seems, she was thrown about for three years, never meeting with a person who could fully appreciate her talents; and we have it from her own lips, that not until after the arrival of Jenny Lind and Parodi in the country, was she aware of the high character of her own talents. She knew she possessed them, because they were inherent, inseparable with her being. She attended the Concerts of Mad'll. Jenny Lind, and Operas of Parodi, and at once saw the "secret of their success"—they possessed talents, that no other popular singers mastered.

She went home; her heart fluttered; she stole an opportunity when no one listened, to mock or gossip; let out her voice, when ecce! she found her strains four notes above Sweden's favored Nightingale; she descended when lo! she found her tones three notes below! she thanked God with a "still small voice"; and now, she ranks second in point of voice, to no vocalist in the world. Miss Greenfield, if she only be judicious and careful, may become yet, in point of popularity, what Miss Lind was. The Black Swan, is singing to fine fashionable houses, and bids fair to stand unrivalled in the world of Song.

Patrick Henry Reason, a gentleman of ability and fine artist, stands high as an Engraver in the city of New York. Mr. Reason has been in business for years, in that city, and has sent out to the world, many beautiful specimens of his skillful hand. He was the first artist, we believe in the United States, who produced a plate of that beautiful touching little picture, the Kneeling Slave; the first picture of which represented a handsome, innocent little girl upon her knees, with hands outstretched, leaving the manacles dangling before her, anxiously looking and wishfully asking, "Am I not a sister?" It was beautiful—sorrowfully beautiful. He has we understand, frequently done Government engraving. Mr. P.H. is a brother of Professor Charles L. Reason.
