If we substitute the two values found for V in the first of 
tae (Xvi) whereby « is at one time made = 0 and the 
other time = 0-05, we obtain as corresponding quantities of work 
expressed in kilogram-meters, 
14990 and 14450. 
That this value is greater than that previously found for the 
Same quantity of steam, 0°3637, may be explained from this, 
that we have hitherto considered the volume of steam at the max- 
imum density, as greater than it can be according to the mechan- 
Ieal theory of heat, and this earlier view finds also its expression 
In equation (29;.) \ 
If we determine by means of this volume the work under the 
two suppositions that « = 0 or = 0° 
16000 and 15200. 
These quantities of work are, as was to be foreseen as immediate 
Consequences of the greater volume, both greater than those be- 
forehand, but not in an equal ratio, masmuch as the loss of work 
occasioned by the injurious space is less, according to the equa- 
oe developed by us, than it should be according to Pambour’s 
eory. oe

studied in action, the velocity which the machine actually as-

muination of ¢, described in § 47, we obtain in succession the fol- 
lowing approximate values:
