Had Mr. Rittenhouse taken an Orrery to England, and it appears by his letters of March 15, 1771, and Feb. 3, 1772, quoted in the text, that he had seriously intended going thither, he would, very probably, have derived great emolument, as well as fame, by delivering lectures on astronomy, adapted to his orrery; and it is probable, that, in addition to the public encouragement he might reasonably have calculated upon, Mr. Penn would have patronised him, with his usual liberality. Of the disposition of that worthy gentleman to befriend him, Mr. Rittenhouse seems to have been fully sensible: for, in a letter of the 11th of December, 1768, to Mr. Barton, he said—“I am very desirous to send Mr. Penn something: as the orrery is not finished, perhaps a description of it, with draughts of the clock I have just made, may answer the purpose, together with some little instrument: I shall be glad to have your thoughts on the matter.” It may be proper here to remark, that no engraving, or drawing, could give an adequate idea of the orrery: and that the clock, mentioned by Mr. Rittenhouse, was one of those of which a short notice is introduced, immediately after the original description of the orrery, in the text.

[143]. The glass-house mentioned in the text, was erected several years prior to the American revolutionary war, at the village of Manheim, about twelve miles from the borough of Lancaster, by Mr. Henry William Stiegel, an ingenious and enterprising German gentleman. Glass of a very good quality and workmanship[workmanship], was made at that glass-house; as will appear by the following extracts from a letter of Mr. Rittenhouse to Mr. Barton, written in the summer of 1771, and acknowledging the receipt of a barometer-tube executed there. He says—“I am obliged to you for the glass tube; it will make a pretty barometer, though the bore is somewhat too small. I have compared it with an English tube, and do not think the preference can, with any reason, be given to the latter.” And in the same letter, he requests Mr. Barton to procure for him, from the glass-house, “some tubes of a size fit for spirit-levels.” “The bore,” says he, “must be half an inch in diameter, and from four to eight inches in length; as straight as possible, and open at one end only.”

While Mr. Stiegel was thus early and meritoriously carrying on the manufacture of glass, he was also engaged in manufacturing iron at Elizabeth-Furnace in the vicinity, which then belonged to him. But he proved unfortunate in his extensive undertakings, and the glass-works[glass-works] have not since been in operation. The foundery of Elizabeth, together with the great establishment of iron-works connected with it, and of which Robert Coleman, Esq. of Lancaster, is now the proprietor, are well known.

[144]. Dr. Franklin is said to have first met with the Pulse-Glass in Germany, and to have introduced it into England with some improvement of his own.

MEMOIR
OF THE
LIFE OF DAVID RITTENHOUSE;
CONTINUED,
FROM THE TIME OF HIS SETTLEMENT IN PHILADELPHIA.

In the autumn of 1770, our Philosopher changed the place of his residence; removing, with his family, into the city of Philadelphia. To this exchange of his beloved retirement, at his Norriton farm, for the scene of noise and activity presented by a great town, he must have been induced by the flattering prospects of advantage to himself and usefulness to the public, pointed out to him by his friends: and among these, Dr. Smith was one of the most urgent for the measure. The following extract of a letter, dated the 27th of January, 1770, and addressed to the Rev. Mr. Barton by that gentleman, will explain his motives, and at the same time exhibit Mr. Rittenhouse’s views, on that occasion: it will also afford strong evidence of the Doctor’s friendship for our philosopher.

“As my esteem for Mr. Rittenhouse increases, the more I know him,” said Dr. Smith, “I set on foot a project, assisted by my neighbours, the Wissahickon millers, to get him recommended to the Assembly, to be put in as a trustee of the loan-office, in the bill now before the house. I first broke the matter to the speaker;[[145]] telling him, Mr. Rittenhouse ought to be encouraged to come to town, to take a lead in a manufacture, optical and mathematical, which never had been attempted in America, and drew thousands of pounds to England for instruments, often ill finished; and that it would redound to the honour of Philadelphia to take a lead in this, and of the Assembly, to encourage it. The speaker took the proposal well, and, in short, so did every person applied to; and when the vote passed, the day before yesterday, for the three trustees, the whole house rose for Rittenhouse’s name; so that Mr. Allen,[[146]] who was hearty among the rest for him, observed—“Our name is Legion, for this vote,”—though Dr. M—— got in only by the speaker’s casting vote.

“This will give you pleasure, as it shews that a good man is capable of sometimes commanding all parties; and it will be creditable for Mr. Rittenhouse, even if the bill should not succeed for the present. The salary to each of the trustees is 200l.[[147]] Both the Mr. Ross’s,[[148]] Mr. Biddle,[[149]] and Mr. Carpenter,[[150]] were hearty in their interest for Rittenhouse,—so was Minshull;[[151]] and I hope you will thank them all. The governor[[152]] declared (and with more frankness than usual,) when I waited on him,—“Mr. Rittenhouse’s name shall never be an objection with me, in this or any other bill: on the contrary, I shall rejoice if the bill come to me in such a form, as that I can shew my regard for him.”

“Yet, my dear friend,” adds Dr. Smith, “I fear this bill will not pass; and the Governor may be reduced to the hard dilemma, of even striking out the name he would wish in, if he had the nomination himself. The house insist on putting the names in the bill, before it goes up: the Governor contends, that he ought to have at least a share in the nomination. This matter has been long litigated. The governor, to maintain his right, always strikes out some names—even though he approves of them, and puts in others. This he did last year, and put in the name of Dr. M——, and the other trustee now in the bill. The house would not admit his amendment, then; but now, this year, they take two of the very men the governor had appointed last year, vote them in themselves, and join Mr. Rittenhouse with them. The governor cannot well negative any of those approved by him, before; yet he must negative some one, to assert his right;—and I believe it would really give him pain, if that one should be David.

“I am thus particular,” continues the Doctor, “that you may understand the whole, and not think our friend slighted by the government, even if this thing should not succeed. All the council[[153]] are hearty for Mr. Rittenhouse; and if he does not get this matter, he will not be long without something else. But I hope some expedient may be hit upon, to compromise the matter, should the bill not have faults in itself, that may set it aside.”
