In his friendship, as in all his social affections, he was perfectly sincere; for, his ardent love of truth led him to detest every species of dissimulation. He was warmly attached to many estimable characters, among those with whom he was acquainted; and he enjoyed, in return, their friendship and respect: besides which, he possessed in an high degree the esteem of all his fellow-citizens, to whom his name and character were well known. With not a few persons, who were either distinguished by literature and science, or by ingenuity, and information on general topics or particular subjects of useful knowledge, he was in habits of intimacy: in the list of these, might be placed several of the most eminent and dignified characters in America. Dr. Rittenhouse’s epistolary correspondence, even with his personal friends, was by no means extensive: indeed the most of these, after his removal to Philadelphia, were there his fellow-citizens. His almost incessant employment, either in public or private business, occupied his time so fully as to allow him little leisure, when in the enjoyment of health; and sensible of the repeated inroads which the privation of this blessing made on his profitable time, he was covetous of every hour, in which his industry could be most conveniently as well us usefully engaged. He therefore, like the celebrated Dr. Bradley,[320] published little. Possibly, too, this circumstance in relation to both these great astronomers, may have been, in some degree, occasioned by similar motives, a natural diffidence in their own faculties, extraordinary as others knew them to be. The English philosopher is even said to have been apprehensive, that a publication of his works might prove injurious to his reputation; and, therefore, he suppressed many of his papers: but whether our astronomer made preparations for publishing any large systematic work, in his favourite science, cannot be ascertained; the probability however is, that he did not, for want of time and health to engage in such an undertaking. ----- Footnote 320: An eulogy of this great astronomer, celebrated for his discovery of the aberration and nutation, will be found in the History of the French Academy, for the year 1762. He was born in 1692; and died at Greenwich, in 1762, at the age of seventy years. -----
