Page 46 - SATURDAY REVIEW. Wilson (JM) — ELEMENTARY GEOMETRY. Books I. II. III. Containing the Subjects of Euclid's first Four Books. New Edition, following the Syllabus of the Geometrical Association. By JM WILSON, MA, late Fellow of St. John's College, Cambridge, and Mathematical Master of Rugby School.
Page 394 - For nearly two years I have felt quite sure that the proper explanation of voltaic action in the common voltaic arrangement is very near Volta's, which fell into discredit because Volta or his followers neglected the principle of conservation of force.

Page 381 - The paper concludes as follows : — " An interesting physical speculation connected with this working hypothesis is the effect on the period of duration of a star's heat which •would be brought about by assuming that the original atoms of which a star is composed are possessed of the increased potential energy of combination which this hypothesis endows them with. From the earliest phase of a star's life the dissipation of energy would, as it were, bring into play a new supply of heat, and so...

Page 364 - Rutherford's researches, very small. As the electric arc in its usual vertical position gave all the lines from pole to pole, the lamp was placed on its side, and the arc used in a horizontal position, the slit being vertical. The dense core of the arc then gave all the short lines in the centre of the field, the longer ones extending beyond them on either side. In order to obtain a scale, it was resolved to photograph the solar spectrum immediately adjacent to the metallic spectrum under examination....
Page 365 - We have here, then, a case of coincident lines, in which the one that is long and bright in one spectrum is short and faint in the other, and a case of a line said to be coincident in two spectra being, though always visible in one, sometimes absent in the other of them, and only appearing in it when the two substances were mixed. The hypothesis of impurity at once explains the whole case, even without the third line, which renders the fact of mixture certain. The longest lines of calcium occur in...
Page 363 - I am of opinion that the syren, performing from 2000 to 2400 revolutions a second, or, in other words, generating from 400 to 480 waves per second, best meets the atmospheric conditions. "We varied the pressure from 40 to 80 Ibs. on the square inch ; and though the intensity did not appear to rise in proportion to the pressure, the higher pressure yielded the hardest and most penetrating sound. The 20th was a rainy day with strong wind. Up to a distance of 5£ miles the syren continued to be heard...

Matteucci has shown that twisting a magnet lessens its force, but stretching a magnet slightly adds to its power} ; and according to M. Guillemin, a strip of iron bent by its own weight is partly straightened by magnetization.
Page 370 - Canada balsam in a wide-mouthed square bottle ; let light, polarized in a vertical plane, be transmitted through the fluid ; observe the light through a Nicol's prism, and turn the prism so as to cut off the light ; insert a spatula in the Canada balsam, in a vertical plane passing through the eye. Whenever the spatula is moved up or down in the fluid, the light reappears on both sides of the spatula ; this continues only so long as the spatula is in motion. As soon as the motion stops, the light...
