The executive committee of the Board of Regents respectfully submit the following report in relation to the funds of the Institution, the receipts and expenditures for the year 1874, and the estimates for the year 1875: Statement of the fund at the beginning of the year 1875.
Page 164 - Gentlemen, that in questions of science the authority of a thousand is not worth the humble reasoning of a single individual.
Page 9 - The amount originally received as the bequest of James Smithson, of England, deposited in the Treasury of the United States in accordance with the act of Congress of August 10, 1846...
Page 12 - Problems of Rotary Motion presented by the Gyroscope, The Precession of the Equinoxes, and The Pendulum.
Page 215 - A strong iron tube, about four inches in diameter, is firmly bolted to a wharf or pile. It is open at the top, and has at the lower end a nipple to which an India-rubber bag is fastened, — the length of the tube being sufficient to allow the elastic bag to be always submerged at the lowest stage of the tide. The bag is supported by a suitable shelf, or cage, and is filled with glycerine, which is poured in at the top of the tube. When in this condition the glycerine rises and falls within the iron...
Page 166 - ... with those of another. This object was accomplished by Laplace, who discovered that notwithstanding the perpetual fluctuations of the planetary orbits, there exists a fixed plane, to which the positions of the various bodies may at any instant be easily referred. This plane passes through the center of gravity of the solar system, and its position is such that if the movements of the planets be projected upon it, and if the mass of each planet be multiplied by the area which it describes in a...
Page 222 - ... direct course to deep water. We have here the total obstruction of a channel, which was of considerable importance to the southward trade, by new conditions introduced at a point four miles distant from where the effect was produced, and we are warned how carefully all the conditions of the hydraulic system of a harbor must be investigated before undertaking to make any change in its natural conditions, lest totally unlooked-for results be produced at points not taken into consideration.
Page 362 - Very brittle, of a purplish color ; remarkable both for the absence of animal matter and for the presence of the acid phosphate of lime.

TABLE No. 1. — The plan of this table is taken from Foster's work on the prehistoric races of the United States, and the letters at the heads of the columns refer to the same measurements. Four other columns are, however, added, the first giving the capacities in cubic inches ; an important point omitted...
Page 164 - The calculus of probabilities, when confined within just limits, ought to interest, in an equal degree, the mathematician, the experimentalist, and the statesman. From the time when Pascal and Fermat established its first principles, it has rendered and continues daily to render services of the most eminent kind. It is the calculus of probabilities, which, after having suggested the best arrangements of the tables of population and mortality, teaches us to deduce from those numbers, in general so...
