432 SUMMARY ction 9i (13), function 92, obtained from «i by replacing and the cosines by и>2 and sines, and function Og (16). The sum ?i"b92 of the two first of these functions determines a flow of which the velocity projections on the axes are — and and which has no circulation around the lamina; the third function adds to the flow a circulation of magnitude 2^ around the lamina. Both projections X and Y of the pressure are positive. The first of these projections produces suction. The formulae obtai ­ ned for X and Y fully agree with the general theorem enuncia­ ted by Prof. Joukowsky in the paper „On Adjoined Vortices"-
