But the more solid book-learning given to the girls of New England, even in the public schools, is known only to the daughters of the higher classes, and among them an instance like that of Lady Jane Grey could scarcely now be found. As the girls and boys are never taught in the same schools, no taste is aroused by the example of manly studies. An English girl is astonished to hear that an American girl passes a public examination, like her brothers, and with them competes for prizes; she doubts the truthfulness of some of the representations of life found in American novels; and so little is the freedom of manners understood, that the American traveller is frequently asked,—"Can it really be as Mrs. Stowe represents in America? Does a young lady really give a party herself?"

The difference that one would expect is found between the women of England or Scotland and the women of New England. The young Englishwoman is tasteful and elegant, mindful of all the proprieties and graces of social life; she speaks slowly and cautiously, and gives her opinions with great modesty. These are not at present the characteristics of the American girl.

Mary Fairfax passed through the usual routine. At fourteen she had read the books to be found in her father's house, including the few works on Navigation which were necessary to him in his profession. She had thus obtained an idea of the world of science, and it was dull to return to worsted-work for amusement. The needle, which has been the fetter of so many women, became, however, in her hand, magnetic, and pointed her to her destiny. She was in the habit of taking her work into her brother's study, and listening to his recitations; the revelations of Geometry were thus opened to her; she listened and worked for a time, until the desire to know more of this region of form and law, of harmony and of relations, became too strong to be resisted; the worsted was thrown aside, and she ventured to ask the tutor to instruct her. The honest man told her that he was no mathematician: he could lend her Euclid, but he could do no more.

The first great step was now taken; Euclid was quickly read; other books were borrowed from other friends; Bonnycastle's and Euler's Algebra were obtained, and she exulted in the use of those mystic symbols, x, y, and z. Her parents looked on with indifference; so that the music were not neglected and the governess reported well of her studies, they felt there was no harm in her amusing herself as she chose. When the days of the governess were over, the young lady "came out" in Edinburgh, and mingled much with the best society. This most picturesque city had long been the resort of the most gifted minds; men of literature and men of science made the charm of its winter life. Never was it more the gathering-place of intellect than in the early part of this century; but there was no room for a woman of genius, and the young girl's friends advised her to conceal her pursuits. Move as quietly, however, and as unobtrusively as she might in the brilliant circle, her genius was not without recognition. There was a word of encouragement from Professor Playfair. "Persevere in your study," said he; "it will be a source of happiness to you when all else fails; for it is the study of truth." She had a champion, too, in the dreaded critic, Jeffrey. "I am told," said a friend, writing to him, "that the ladies of Edinburgh are literary, and that one of them sets up as a blue-stocking and an astronomer." "The lady of whom you speak," replied Jeffrey, "may wear blue stockings, but her petticoats are so long that I have never seen them."

Mrs. Somerville has been twice married. Her first husband, a gentleman of the name of Greig, regarded her pursuits as her parents had, simply with indifference. Dr. Somerville, her present husband, has taken the utmost pains to secure her time for her studies, and has himself relieved her from many household cares.

The simplicity of character which belonged to her in early life was not lost when her reputation became established. The Royal Society, whose doors do not open at every knock, admitted her to membership, and, by their order, her bust was sculptured by Chantrey, and now adorns the hall of the Society in Somerset House. During the sittings for this purpose, a lady, a friend of the sculptor, him to introduce her to Mrs. Somerville. Chantrey consented, and made a dinner-party for the purpose. The two ladies were placed side by side at table, and the benevolent artist rejoiced to perceive, from the flow of talk, that they were mutually pleased. The next day, to his astonishment, his friend called on him in a state of great indignation, believing herself the victim of a practical joke. "How could you do so?" said she. "You knew that I did not want to know that Mrs. Somerville; I wanted to know the astronomer: that lady talked of the theatre, the opera, and common things."

The anecdote so often told of Laplace's compliment is literally true. Mrs. Somerville dined with this great geometer in Paris. "I write books," said Laplace, "that no one can read. Only two women have ever read the 'Mécanique Céleste'; both are Scotch women: Mrs. Greig and yourself."

Upon the "Mécanique Céleste" Mrs. Somerville's greatest work is founded. "I simply translated Laplace's work," said she, "from algebra into common language." That is, she did what very few men and no other woman could do. It is of this work of Laplace that Bonaparte said, "I will give to it my first six months of leisure." The student who reads it by the aid of Dr. Bowditch's notes has little idea of the difficulties to be met in the original work. Even Dr. Bowditch himself said, "I never come across one of Laplace's 'Thus it plainly appears,' without feeling sure that I have got hours of hard study before me, to fill up the chasm and show how it plainly appears."

This "translation into common language" was undertaken at the request of Lord Brougham, who desired a mathematical work suited to the "Library of Useful Knowledge." The manuscript was submitted to Sir John Herschel, who expressed himself "delighted with it,—that it was a book for posterity, but quite above the class for which Lord Brougham's course was intended." It was published at once, and became the text-book for the students of Cambridge.

"The Connection of the Physical Sciences" and the "Physical Geography" are the later works of Mrs. Somerville. These volumes have probably been more read in our country than in Europe; for it is a common remark of the scientific writers of Great Britain, that their "readers are found in the United States." They contain vast collections of facts in all branches of Physical Science, connected together by the delicate web of Mrs. Somerville's own thought, showing an amount and variety of learning to be compared only to that of Humboldt.
