(Sketches 572-575.) The derivation of the designs seen in sketches 577 and 578, in-terpreted as clouds, is known to have developed from thosegiven in sketches 93 and 94 (p. 310). boas) geometric forms 327 The trapezoids in Sketch 580 may have arisen from a mistake inthe creation of the lowest one, or from a miscalcuhition in the draw-ing of a pattern of triangles, the oblique lines not slanting sharplyenough for the width of the stripe.
