For the latter purpose we draw the concentric circles representing lines of equal intensity for the luminous source , and similar lines of equal negative intensity for the imaginary source occupying the dark space ; by the process above ...

In two - dimensional fluid inotion , the image of a linesource outside and parallel to the axis of a cylinder is an equal line - source through the inverse point together with an equal line - sink through the centre ( i . e . along the ...
