Velocity and Magnitude cf WaVes.

 The velocity of waves is related to their

 magnitude. Some large waves proceed at the rate of from thirty to forty miles an

 hour. It is a vulgar Belief, that the water

 itself advances with the speed ofthe wave;

 but, in fact, the form only advances, while

 the substance, except little spray above, Eremains rising and falling in tho same place, according to the laws of the pendulum. A

 wave of water, in this respect, is exactly

 initiated by the wave running along

 stretched rope when on6 end of 1t is shak~

 en; or by the mimic waves of our theatres,

 which are generally the undula.ions of long

 pieces of carpet, moved by attendants.-- But when wave reaches shallow bank

 or beach, the water becomes really progress

 siye because then, as it cannot sink di-

 rectly downwards,it it falls over and forwards ] seeking it's level. So awful is the spectacle

 of storm at sea, that it is generally view ed through a medium which biasses the tiudgment; and, lofty as waves really are, . imagination makes them loftier still. No waves rise more than ten feet above tho ordinary level, which with the ten feet that its surface afterwards descends, below this, gives twenty feet for the whole height from '. inc bottom of any water valley to the sun'- |, init. This proposition is easily proved, by . irving the height on ships mast. at which the horizon is always in sight over the soPs ] Eof the waves; allowance being made for : accidental inclinations of the vessel, and for ! her sinking in the water to much below her water line. aa tie iassaRt when she reaches }. inc bottom of the hollow between two waves. The spray of the sea driven by the f violence of the winds is of course much f higher than the summit of the liquid wave; e and wave coming against an obstacle may '- dash to almost any elevation above 1t. At y the Eddyston Lighthouse, when surge J. reaches it, which has been growing under !" a strom. all the way across the Atlantic, Ie e dashes even over the lantern at the summit. q .
