E. Seguin, Popular Science Monthly (1877)
“ To see, and not be able to reach, to perceive images, with no possibility of seizing the objects, renders him impatient, fretful, or unconcerned, and opens an era of exaction upon others, or of diffidence of himself, or of indifference for any attainment, which unavoidably ends in immorality or incapacity, or in both. Viewed from this standpoint, these cradles, so varied, so elegant, so easy to keep clean, and to carry from the light of the window by day to the recess of the alcove at night—the best being of French and Austrian manufacture—are yet very imperfect in their bearing on education. ”
