It requires an apology that I have not before now sent you the Time-Piece, which has been so long in my custody. The commencement of the late war before the Time-Piece was finished, & the consequent depredations of the enemy on our coast, prevented its being sent before the restoration of peace. When this event had taken place, I perceived that some parts of the veneering were scaling off from...
I am directed, by the Philosophical Society , to acknowledge the reciept (under cover from you) of a paper from M. Du Jareau of New Orleans , on the construction of a saw-mill to be worked by a horse. This paper, according to the usage of the society, was referred to a committee , who have reported, in substance, —That the paper does not appear to be intended by the Author as a communication...
My younger son, Robert Maskill , having gone thro the usual course of collegiate studies in our Seminary , and of medical studies under D r Barton , and obtained degrees both in the Arts & in medicine; has devoted the last twelve months chiefly to the study of mineralogy under M r Godon ; in which, it is said, he has made considerable proficiency. He has a strong desire of visiting some parts...
Your time-piece has been packed up, ready for shipment, in the manner you directed, for a considerable time. But as soon as our river was had been rendered navigable, by the breaking up of the ice, it was again stoped & still continues to be so, by a British fleet. I am therefore, Sir, about to set it up at my own house, as it will be better to keep it going than standing; & shall wait your...
I have rec d & read your interesting communication of the 10 th Nov r with great satisfaction, and have laid the same before the Committee appointed on the subject of your former communication; who, I am sure, will give it that consideration which it so highly merits. In the meantime, Sir, you will permit me to make a few observations, which may not, however perfectly agree with the ideas...
Presuming that you may not as yet have seen a little tract, by Doctor Buchanan , on “Christian Researches in Asia ,” lately republished in Boston ; and not doubting that you would find it highly interesting, I have taken the liberty of sending you a copy, of which I most respectfully request your acceptance. Some time ago, inclosed I believe in A Nautical Almanack for the year 1813, I returned...
You have no doubt been informed, at least thro the medium of News-papers, of M r Peale ’s complete success in illuminating his Museum with gas - lights , & presuming that it would not be uninteresting to you, I shall do myself the pleasure of giving you a description of his apparatus & process for generating & distributing the gas. It is well known that any substance containing hydrogen will,...
Some days ago, I received your favour of the 11 , with the French poem on Astronomy. The Society had rec d a copy of the same work from the Author , & therefore they wish me to return your copy. They have eagerly embraced your proposal respecting the universal standard of weights and measures , and have referred the subject to a Committee who earnestly solicit, not merely your co-operation,...
A considerable time ago, you made some enquiries relative to a good clock & watch-maker , who, you suggested, might advantageously settle in your neighbourhood. Neither then, nor since, till the other day, could I hear of one that I could recommend, who was willing to make the trial. From the enclosed letter , you will be able to judge whether the persons therein Recommended by m r Hassler ,...
I have been favoured with your letter of the 13 th & shall immediately take measures to send on your Time-piece as you have directed. I have had, for some years an artificial horizon , which, by means of a reflecting sextant, answers the purpose of measuring all altitudes of the sun, or any other visible object, from 0 to 90° as well as all depressions not exceeding 50° with great ease &...
