73. lappuse - Pressure exerted anywhere upon a mass of liquid is transmitted undiminished in all directions, and acts with the same force on all equal surfaces, and in a direction at right angles to those surfaces.
190. lappuse - ... changes of shape and volume in the bodies impinged upon by the beam. But if this be the case, and if gases and vapours really absorb radiant heat, they ought to produce sounds more intense than those obtainable from solids. I pictured every stroke of the beam responded to by a sudden expansion of the absorbent gas, and concluded that when the pulses thus excited followed each other with sufficient rapidity, a musical note must be the result. It seemed plain, moreover, that by this new method...
271. lappuse - On the lower half of this disk is a graduated semicircle divided into twelve parts (each of which is again subdivided into five or ten parts) , and against the divisions the hours of the day are marked, commencing and terminating with vi. Within the fixed brass ring containing the glass dial-plate, the broad end of a conical tube is so fitted that it freely moves round its own axis ; this broad end is closed by another glass...
271. lappuse - This effect is obtained by placing the principal section of the small central disk 22£° from that of the other films of selenite which form the star. The rule to ascertain the time by this instrument is as follows : the tube must be turned round by the hand of the observer until the coloured star entirely disappears while the disk in the centre remains red ; the hand will then point accurately to the hour.
426. lappuse - The unit of force is that force which, acting for one second on a mass of one gramme, gives to it a velocity of one centimetre per second.
