Страница 213 - That the magnitudes of these standards should be determined on the electromagnetic system of measurement with reference to the centimetre as unit of length, the gramme as unit of mass, and the second as unit of time, and that by the terms centimetre and gramme are meant the standards of those denominations deposited with the Board of Trade. (3) " That the standard of electrical resistance should be denominated the ohm, and should have the value 1,000,000,000 in terms of the centimetre and second.
Страница 89 - Dublin, at such time as shall be specified in such notice, or in default thereof they will be excluded from the benefit of any distribution made before such debts are proved.
Страница 168 - Closer study of the two paths of discharge showed that the oblique arc left the very apex of the point, swinging out laterally into its path ; also that the normal arc, on approaching the point, avoided the apex and entered the wire from the side, never passing in at the point itself. From these observations it appears : — 1. That the discharge from the ball (positive) leaves the latter in a direction normal to the surface, but that it enters the other terminal at some distance from the apex. 2....
