The resistance offered was veryunequal, it could not be expected otherwiseon account of the masses full of principal current ran from the middleof the mare Foecunditatis, then through themare Crisium where, most hkel}^, as shownby the photochrome, in consequence of adelay in the unhindered flow some magmaremained behind. It is A^ery interesting tonotice how clearly this is demonstrated bythe moon-picture of Miethe and Seegert andthe Pickering atlas 3 C. With regard to thewrinkles it is shown, that they do not folloAVthe borders so much as the direction of thecurrents, and that they extend from thesouthern to the northern valleys. Fig. 10.
