On a bare heath lies his skeleton, and near the outstretched remnant of his hand is the sword with which he had fought the battle HIC of existence, broken and useless. FINIS LABORUM ! Almost one hundred and fifty engravings wrought by the hand of Anderson after he had passed his ninetieth year, have been handsomely printed from the original blocks, by young Charles L. Moreau, of New York city, on his private press. The engravings, with pleasant introductory remarks by Mr. Evert A. Duyckinck, make a volume of eighty pages. Only fifty copies have been printed. Dr. Anderson was a graduate of the Medical School of Columbia College. He practiced the healing art a few years. It was always distasteful to him, and he was easily wooed and won by the more attractive features of art. He was an engraver actively practising the profession for about seventy-five years. RITTENHOUSE'S orrRERY. John Jacobs or Jacob emigrated from Germany about the year 1700, and settled upon a portion of the Van Bebber tract in Providence Township, Philadelphia, (now Montgomery) County. He died about the year 1728, leaving three children, John, Richard and Rebecca. John, the eldest, obtained the paternal estate, and spent his life upon the banks of the Perkiomen, as a thrifty farmer and esteemed member of the Society of Friends. He died on the 23d of January, 1773, in the 85th year of his age, and an obituary notice of unusual impressiveness appeared in the Penn'a Gazette of February 3d, attesting his reputation for integrity and worth. He had nine children, of whom John, who lived in Whiteland Township, Chester County, represented that county in the Assembly, from 1762 to 1776 inclusive, and the last year of this long term, was chosen speaker. He was also a member of the provincial Convention which assembled in Philadelphia in 1776, and in 1779 was appointed one of five commissioners to meet an equal number from each of the other Provinces to determine upon a limitation of prices. Israel lived in Providence Township, was elected commissioner of Phila. County, in 1765, and held a seat in the Assembly from 1770 to 1774 inclusive. He was appointed by the Council of Safety, one of the committee to distribute food and clothing among the families of poor soldiers during the revolution and became a member of the second United States Congress, in 1791. Joseph carried on business extensively as a merchant, in Philadelphia, as early as the year 1751. Benjamin was employed for many years by the government and by individuals, in surveying lands throughout the Province, was a member of the Provincial Convention of 1775, and also of the Phila. County Committee at the beginning of the revolutionary war. Elizabeth married Caleb Parry, the brave Lieut. Colonel who afterward fell at the head of his battalion at Long Island; and Hannah in December, 1772, married David Rittenhouse. The other members of this honored family were, Mary, Isaac and Jesse, of whom the last named served during the revolution as a Sergeant in the Sixth Maryland regiment. The three brothers, Israel, Joseph and Benjamin, engaged largely in land speculations in Pennsylvania, and together with Dr. William Smith, William Moore, of Moore Hall, Joseph Richardson, Thomas Barton, John Hall, William Craig and John Bayley, as "William Smith and Company," purchased an interest in one hundred thousand acres in Nova Scotia, where they laid out two towns, Monckton and Franckfort, and attempted to found a colo That ingenious piece of mechanism is in the College at Princeton, New Jersey. On the front of it is the incsription: "Invented by David Rittenhouse. A. D., 1768; repaired and extended by Henry Voight, 1806; both of Philadelphia. Dr. Gordon, the historian of the Revolution, writing about this planetarium, in 1793, says: "There is not the like in Europe. An elegant and neatly ornamented frame rises perpendicular near upon eight feet, in the front of which you are presented, in three several apartments, with a view of the celestial system, the motions of the planets around the Sun, and the satellites about the planets. The wheels &c., that produce the movements are modest estimate he himself placed upon his celebrated invention. The other was evidently written at his request as a testimonial. SAML. W. PENNYPACKER. Philadelphia, April, 1873 "Astronomy which is acknowledged to be the most sublime of human sciences, has by a long course of gradual improvements, at length arrived to a great degree of perfection, nevertheless it is not complete, for not to reckon upon many yet unthought of discoveries, which are no doubt still reserved to reward the Industry of future ages, there are many things that we sensibly want, to obtain which at present, either the accuracy of our Astronomical Instruments are not equal to, or good observations have not yet been continued long enough. It is well known that there are certain times particularly advantageous for making such observations as may serve to ascertain such parts of Astronomy as still remain doubtful. The new Orrery lately erected in this City, is designedly adapted to save the laborious task of calculating those times, for by an easy motion of the hand, it will in the space of a few minutes, point out the times of all remarkable phenomena of the Heavenly Bodies for years to come. The advantage it has in this and other respects above Common Orrerys, is owing to the in the motions and disposition of its parts, exact proportion which has been preserved and which it is very difficult to preserve. For the velocities and distances of the planets are so disproportioned and incommensurable to each other, that it is not easy to represent any two of them with tolerable accuracy by wheel-work. "On this account likewise this Orrery must be useful to young beginners in behind the wooden perpendicular frame, in which Astronomy, for it will convey a true idea the orrery is fixed. By suitable contrivances, you in a short time tell the eclipses of the sun and moon for ages past and ages to come the like in other cases of Astronomy.' It is said that Cornwallis, while at Princeton, contemplated carrying off this exquisite piece of mechanism, but the Americans kept him too busily engaged in affairs of personal moment, to permit him to plunder the College of this treasure.-[ED.] of the relative distances of the several parts of the Solar System, and of the various inclinations of the plains of the planet's orbits, which cannot be well exwhich are falsely represented by common plained by lines drawn on paper, and Orrerys, and thus by removing some of |
