In studying* the moon-wrinkles the ex-plorer encounters different typical appearan-ces : For tlie first, these wrinkles are onh^to be found in flat countries of the moonssurface; for the second, these formations arenever suddenly interrupted in their lengthand in the third place their height is with-out exception so insignificant, that for theircloser observat
