Page 144 - THE BOYDEN PREMIUM URIAH A. BOYDEN, ESQ., of Boston, Mass., has deposited with THE FRANKLIN INSTITUTE the sum of one thousand dollars, to be awarded as a premium to "Any resident of North America who shall determine by experiment whether all rays of light,* and other physical rays, are or are not transmitted with the same velocity.
Page 216 - The course of the Stevens Institute is of four years' duration, and covers all that appertains to the profession of a Mechanical Engineer. By means of workshops provided with excellent machinery, Physical Laboratories whose appointments are without an equal, and with the finest Cabinets of Instruments, every opportunity for the acquisition of thorough and practical knowledge is afforded.
Page 362 - But Knowledge to their eyes her ample page, Rich with the spoils of time, did ne'er unroll ; Chill Penury repressed their noble rage And froze the genial current of the soul.
Page 216 - Trigonometry. Candidates for admission to the higher classes must be prepared to pass a satisfactory examination in all the studies previously pursued by the classes which they propose to enter. Advanced students and men of science desiring to avail themselves of the appliances of the laboratories of the Stevens Institute, to carry on special investigations, may apply to the President. For further particulars address the President, H. MORTON, Hoboken, NJ A MECHANICAL LABORATORY ha...
Page 199 - I am still obliged to give the pressures in atmospheres as indicated by an air- or hydrogen-manometer, without attempting for the present to apply the corrections required to reduce them to true pressures. The only satisfactory method of obtaining these corrections would be to compare the indications of the manometer with those of a column of mercury of the requisite length ; and this method, as is known, was employed by Arago and Dulong, and afterwards in his classical researches by Regnault, for...
Page 206 - azotic gas, hydrogenous gas, carbonic acid gas, aqueous vapour, and probably several other elastic fluids may exist in company under any pressure and at any temperature without any regard to their specific gravities, and without any pressure upon one another.
Page 205 - ... atmosphere. Still more important is the change in the value of the coefficient at different parts of the thermometric scale, the pressure remaining the same. An inspection of the figures will also show that this change of value at different temperatures increases with the pressure. Another interesting question, and one of great importance in reference to the laws of molecular action, is the relation between the elastic forces of a gas at different temperatures while the volume remains constant....
Page 198 - The investigation to which this note refers has occupied me, with little intermission, since my former communication in 1869 to the Society, " On the Continuity of the Liquid and Gaseous States of Matter." It was undertaken chiefly to ascertain the modifications which the three great laws discovered respectively by Boyle, GayLussac, and Dalton undergo when matter in the gaseous state is placed under physical conditions differing greatly from any hitherto within the reach of observation. It embraces...
Page 67 - When I consider the variety of theories that may be formed on the slender foundation of one or two facts, I am convinced that it is the business of the true philosopher to avoid them altogether. It is more laborious to accumulate facts than to reason concerning them ; but one good experiment is of more value than the ingenuity of a brain like Newton's.
Page 224 - York, and of the tabulations and deductions from the reports of the Railroad corporations made to the board for the year ending Sept.
