Accordingly for a given ellipsoid the surface density of free distribution of electricity on it is everywhere proportional to the the tangent e plane e **att** that point.

15.6 Tons 15.2 Tons steam-engine, representing graphically by a curve CPD the relation between the volume and pressure of the powder-gas; and in addition the curves AQE of energy e, AvV of velocity v, and **AtT** of time t can be plotted or derived, the velocity and energy at the muzzle B being denoted by V and E.

3 parallel to AM; the energycurve AQE would be another straight line through A; the velocitycurve AvV, of which the ordinate v is as the square root of the energy, would be a parabola; and the acceleration of the shot being constant, the time-curve **AtT** will also be a similar parabola.

"**Att-ention**!" shouted the regimental commander in a soul-shaking voice which expressed joy for himself, severity for the regiment, and welcome for the approaching chief.
