Moring's Quarterly says in regard to the special work which Mrs. Mansfield has done: "It is so seldom that an artist is able to take in hand what may be termed the entire decoration of a book—including in that phrase cover, illustration, colophon, head- and tail-pieces, initial letters, and borders—that it is a pleasure to find in the subject of our paper a lady who may be said to be capable of taking all these points into consideration in the embellishment of a volume."

Medici, Marie de'. Wife of Henry IV. Born at Florence, 1573; died at Cologne, 1642. A portrait of herself, engraved on wood, bears the legend, "Maria Medici F. MDLXXXII." Another portrait of a girl, attributed to her, is signed, "L. O. 1617." It may be considered a matter of grave doubt whether the nine-year-old girl drew and engraved with her own hand the first-named charming picture, which has been credited to her with such frank insouciance.

Mengs, Anna Maria. Member of the Academy of San Fernando. She was a daughter of Anton Rafael Mengs, and was born in Dresden in 1751, where she received instruction from her father. In 1777 she married the engraver Salvador Carmona in Rome, and went with him to Spain, where she died in 1790. Portraits and miniatures of excellent quality were executed by her, and on them her reputation rests.

Merian, Maria Sibylla. Born at Frankfort-on-the-Main in 1647. This artist merits our attention, although her art was devoted to an unusual purpose. Her father was a learned geographer and engraver whose published works are voluminous. Her maternal grandfather was the eminent engraver, Theodore de Bry or Brie.

From her childhood Anna Sibylla Merian displayed an aptitude for drawing and a special interest in insect life. The latter greatly disturbed her mother, but she could not turn the child's attention from entomology, and was forced to allow that study to become her chief pursuit.

The flower painter, Abraham Mignon, was her master in drawing and painting; but at an early age, before her studies were well advanced, she married an architect, John Andrew Graf, of Nuremberg, with whom she lived unhappily. She passed nearly twenty years in great seclusion, and, as she tells us in the preface to one of her books, she devoted these years to the examination and study of various insects, watching their transformations and making drawings from them. Many of these were in colors on parchment and were readily sold to connoisseurs.

Her first published work was called "The Wonderful Transformations of Caterpillars." It appeared in 1679, was fully illustrated by copper plate engravings, executed by herself from her own designs. About 1684 she separated from her husband, and with her daughters returned to Frankfort. Many interesting stories are told of her life there.

She made a journey to Friesland and was a convert to the doctrines of Labadie, but she was still devoted to her study and research. She was associated with the notable men of her time, and became the friend of the father of Rachel Ruysch. Although Madame Merian, who had taken her maiden name, was seventeen years older than the gifted flower painter, she became to her an example of industry and devotion to study.

Madame Merian had long desired to examine the insects of Surinam, and in 1699, by the aid of the Dutch Government, she made the journey—of which a French poet wrote:
