Dr. Rittenhouse named his second daughter, Esther, in compliment to his sister Barton. In a letter to the Rev. Mr. Barton, written on the occasion of the birth of this younger child, he says—“To me, it is a matter of indifference, but to my Eleanor it was a great disappointment, to have a girl, having promised herself a boy; and it had long since been resolved that this child, if a son, should be called Thomas, after yourself.” The eldest daughter was named Elizabeth, after his own mother. ----- The remains of our philosopher were deposited, agreeably to a desire he had expressed long before his death, beneath the pavement within the small Observatory which he erected many years before, in the garden adjoining his house; and over the body was placed a plain slab of marble, inscribed only with his name, the time of his decease, and his age. Although it was intended that his interment should be attended by his family-connexions alone,—in consequence of which, no other persons were asked to the funeral,—a numerous body of his friends voluntarily presented themselves on the occasion, as a mark of their respect for his memory. The Rev. Dr. Green was one of the number; and this clergyman, being then the pastor of the congregation in which the deceased had often attended divine worship in the latter years of his life, delivered a short but appropriate address to a surrounding auditory of mourning and afflicted friends.—“_This_,” began the reverend orator, pointing to the tomb of our philosopher, as just described,—“_This_ is, emphatically, _the Tomb of Genius and of Science_! Their child, their martyr, is here deposited,—and their friends will make his Eulogy, in tears. I stand not here, to pronounce it; the thought that engrosses my mind, is this;—how much more clear and impressive must be the views, which the late Spiritual Inhabitant of that lifeless corpse now possesses of GOD,—of his infinite existence, of his adorable attributes and of that eternal blaze of glory which emanates from Him,—than when she was blinded by her veil of flesh! Accustomed, as she was, to penetrate far into the universe,—far as corporeal or mental vision here can reach,—still, what new and extensive scenes of wonder have opened on her eyes, enlightened and invigorated by death! The Discoveries of RITTENHOUSE, since he died, have already been more, and greater, than while he lived.[306] Yes; and, could he address us from the spiritual world, his language would be— “All, all on Earth is shadow, all Beyond Is substance; the reverse is folly’s creed.”
