direction that the interior of the surface is always on the left hand, is equalto the value taken round the sole infinity, namely the place a, in a counter-clockwise direction. Round the pair a,., br the value obtained is fir I dv. , taken once positively in the direction of the arrow head round… … The relations indicated by the figure for the signs adopted for coir, Tir andthe periods of T will be preserved throughout the book. Since Wi,. is zero except when r = i, the sum of these p contour integralsis —(Oi^iQ^i. Taken in a counter-clockwise direction, round the pole of T^ ,where r = -- +…
