Page 61 - feet are a single thread. I apply a tension which causes the string to divide into two ventral segments. But how does it divide ? Not at its centre, as is the case when the string is of uniform thickness throughout, but at the point where the thick string terminates. This thick segment
Page 327 - must be determined experimentally for each pair of gases. It varies directly as the square of the absolute temperature, and inversely as the total pressure of the mixture. Its value for carbonic acid and air, as deduced from experiments given by Mr. Graham in his paper on the Mobility of GaSeS*, is D=
Page 61 - feet long vibrates as a whole when attached to the fork a. I now transfer it to b, still keeping it stretched by the same weight. It vibrates when 6 vibrates ; but how ? By dividing into two equal ventral segments. In this way alone can it accommodate itself to the

Page 251 - a few bright lines, which indicate that the light by which it is formed was emitted by matter in the state of luminous gas. These spectra are represented with considerable approximative accuracy in a diagram which accompanies this paper. Spectrum of Absorption and Spectrum of Bright Lines forming the Compound Spectrum of a New Star
Page 49 - of muscular fibre, or, as it may be called, a rapid change of matter, determines a greater amount of mechanical force ; and conversely, that a greater amount of mechanical motion ‘(of mechanical force expended in motion) determines a more rapid change ¿f matter.” (Organic Chemistry in its
Page 61 - length by laying four strands of the first side by side. I attach this compound thread to 6, and, keeping the tension the same as in the last experiment. set 6 in vibration. The compound thread synchronizes with 6, and swings as a whole.
Page 48 - lost its chemical character by combining with zinc); and all experience proves, that this conversion of living muscular fibre into compounds destitute. of vitality is accelerated or retarded according to the amount of force employed to produce motion. Nay, it may safely be affirmed, that they are mutually proportional; that a rapid transformation
Page 326 - are equal. The pressure of the gas is on this theory due to the impact of the molecules on the sides of the vessel, and the temperature of the gas depends on the velocity of the molecules. The theory as thus stated is that which has been conceived, with various degrees of clearness, by
Page 117 - electromagnetic machine was constructed : the weight of its electromagnet is nearly 3 tons, and the total weight of the machine is about 44¿- tons. The machine is furnished with two armatures—one for the production of “ intensity”-, and the other for the production of “ quantity”effects . The intensity armature is coiled with an insulated conductor
