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

These spectra are represented with considerable approximative accuracy in a diagram which accompanies this paper.

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 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

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
