In this primeval, or rather timeless because ever-proceeding, sacrifice, time itself, in the shape of its unit the year, is made to take its part, inasmuch as the three seasons - spring, summer and autumn - of which it consists, constitute the ghee (clarified butter), the offering-fuel and the oblation respectively.

The unit of power, called conventionally a horse-power, is 550 foot-pounds per second, or 33,000 foot-pounds per minute, or 1,980,000 foot-pounds per hour.

Of track and yard room required to perform a unit of work;, it has diminished journal and rolling friction relatively to thetons hauled, since these elements of train resistance grow relatively less as the load per wheel rises; and finally, it has tended to reduce the labour costs as the train loads have become greater, because no more men are required to handle a heavy train than; a light one.

Similarly, the heat which accompanies the dissolution of one electrochemical unit of copper is 3.00 calories.

On account of its practical convenience, and its close relation to the international electrical units, the joule has been recommended by the British Association for adoption as the absolute unit of heat.

If we regard this unit as being 4 times a lesser unit, then Aris 7.4 times this lesser unit, and 7 of A is 5.4 times the lesser unit.

A very usual size of cistern forming a convenient unit is one that will hold 20 tons of char.

From their work it follows that the ratio of the weights of oxygen combined with unit weight of carbon in the two oxides is 1.99995, or with somewhat different data, 1.9996.

The divisions again advanced at different hours, the 3rd at 9 A.M., the 2nd at 12:30 P.M., and the brigades and battalions also attacked in succession from the left, thus enabling all the artillery available to unite in covering the advance of each unit in turn.

Let x be the number of molecules which dissociate per second when the number of undissociated molecules in unit volume is unity, then in a dilute solution where the molecules do not interfere with each other, xp is the number when the concentration is p. Recombination can only occur when two ions meet, and since the frequency with which this will happen is, in dilute solution, proportional to the square of the ionic concentration, we shall get for the number of molecules re-formed in one second ye where q is the number of dissociated molecules in one cubic centimetre.
