**Dn**, dorsal nerve.- Let V i and V2 be the potentials at points just outside and inside the surface dS, and let n l and n 2 be the normals to the surface dS drawn outwards and inwards; then - dV i /
**dn**i and - dV 2**dn**2 are the normal components of the force over the ends of the imaginary small cylinder. - Hence the total flux through the surface considered is - {(dV i /
**dn**l)-}-(dV 2 /**dn**2)}dS, and this by a previous theorem must be equal to 47radS, or the total included electric quantity. - The electric force outward from that point is - dV/
**dn**, where do is a distance measured along the outwardly drawn normal, and the force within the surface is zero. - Hence we have - dV /
**dn**= 4lra or a = - (1 /47r) dV /**dn**= E/42r.
