Footnote 208:

Mr. Rittenhouse continued to hold the place of a trustee of the loan-office more than ten years; but on the 1st of April, 1790, a law was passed, by which all the powers and duties of the trustees of that institution were transferred to, and vested in, the treasurer of the state.

Footnote 209:

The loan-office system was kept up, in Pennsylvania, thirty years after governor Pownall wrote.

Footnote 210:

Paper-money was not so well managed in some of the other colonies, where it was issued in too large quantities, and its credit not established on funds sufficiently stable and secure; a circumstance which induced the parliament of Great-Britain to interdict, for a time, further emissions of that sort of money, called bills of credit, by the provincial legislatures.

Although the last emission of loan-office bills of credit, under the colonial government of Pennsylvania, was made in the beginning of the year 1773, the want of this succedaneum for gold and silver, as a circulating medium of commerce commensurate to the encreased population and trade of the country, was experienced some considerable time before. In a letter written by the Hon. Mr. T. Penn to the Rev. Mr. Barton, dated, London, June 17, 1767, the writer says:

“Your account of the increase of the growth of hemp, gives me great pleasure; and I think the demand there has been for wheat, since the date of your letter, must have made the country people rich, even those who were poor before: it will prevent people being under the necessity of parting with their lands, and going to Carolina. Their produce will always bring them money at Philadelphia, notwithstanding there may be some more need for paper-money; yet, when trade is brisk, it circulates faster, and a less quantity will carry on a greater trade: however, I hope, in the next session of parliament, we may get the law which prohibits our making any more, repealed.”

The parliamentary restriction was, in fact, afterwards taken off; and an effort was made, in the beginning of the year 1770, by the legislature of Pennsylvania, to enact a loan-office law, for the purpose of putting in circulation a further emission of paper-money: but the measure then miscarried, in consequence of some disagreement between the governor and the general assembly respecting the right they severally claimed, of appointing the trustees of the proposed loan-office.

In the year 1782, Mr. Rittenhouse was elected a Fellow of the Academy of Arts and Sciences, of Boston: his certificate bears date the 30th of January, in that year. This academy, which Dr. Morse ranks among the first literary institutions in the state of Massachusetts, holds a very respectable station in relation to science: yet it was not established till so lately as May 4, 1780. The end and design of the institution are stated to be—“to promote and encourage the knowledge of the antiquities of America, and of the natural history of the country, and to determine the uses to which its various natural productions may be applied: also, to promote and encourage medical discoveries, mathematical disquisitions, philosophical enquiries and experiments; astronomical, meteorological and geographical observations, improvements in agriculture, arts, manufactures, commerce, and the cultivation of every science that may tend to advance a free, independent and virtuous people.”

Footnote 211:

The number of members in the Boston Academy is never to exceed two hundred, nor to be less than forty. By being limited to so moderate a number as the former, for the greater extreme, this academy will be likely to select suitable persons for the honour of fellowship, with the more discriminating circumspection.

It is supposed to have been somewhat about this time, that Mr. Rittenhouse exercised his ingenuity upon an object, which, though not of great importance, is nevertheless a matter of considerable utility and some curiosity; the invention of an Hygrometer, made wholly of wood. The simplicity of the construction of this instrument, renders it easily attainable by almost every one; and as it is found to answer, very well, the end for which more expensive instruments are often employed, it may be considered as being more generally useful. Descriptions of the construction, and principle of operation, of this Hygrometer, having been furnished to the writer through the obligingness of two of his friends, a very concise account of it, drawn up from those descriptions, is given in the Appendix.

Footnote 212:

Robert Patterson, Esq. Director of the Mint, and David Rittenhouse Waters, Esq. a gentleman bred to the law, and a grandson of the late Dr. Rittenhouse.

The decease of Mr. Waters happened soon after: he died on the 4th of September, 1813, at the premature age of twenty-two years. Although he had just entered on the threshold of the world, this excellent young man exhibited many proofs of extraordinary attainments in literature and science, as well as of a superior genius. He appeared to have inherited from his maternal grandfather, congenial talents. In his life, his amiable disposition endeared him to all who had an opportunity of knowing his virtues: in his death, not only have his relatives and friends experienced an afflicting bereavement, but his country has sustained the loss of a citizen of great promise.

A circumstance shall be noticed in this place, which, although trivial in itself, will serve to shew the grateful sense entertained by our Philosopher of the merits of General Washington. It appears, that just about the time when the provisional articles of peace, concluded on between the United States and Great-Britain, were made known in America, Mr. Rittenhouse had forwarded to the General, at the head-quarters of the army, a pair of spectacles, and reading glasses,—as a small testimonial of his respect for the character and services of that great man. The terms of the letter that accompanied this little present, are not known to the writer of these memoirs; but, of what complexion they were, may be inferred from the General’s answer, which is in these words:

“Newburgh, 16th Feb. 1783.

“Sir,

“I have been honoured with your letter of the 7th, and beg you to accept my sincere thanks, for the favor conferred on me, in the Glasses—which are very fine; but more particularly, for the flattering expressions which accompanied the present.
