It may be noticed that in this formulation of Green's theorem the sign on the right hand side has been reversed from that usually used. This is because we have thought it more natural here to think of the normal derivative as directed into the volume V rather than in the conventional outward direction. In this way the normal derivative is directed away from the earth, and this corresponds to the direction of the normal derivative in Eq. (2).**[10]**See J. A.
