 ... instrument is directed, if it only be in its proper place the effect just described is sure to take place, and with an endless variety. In this respect, the kaleidoscope appears to be quite singular among optical instruments. Neither the instrument...  Journal of Science and the Arts - Pagina 3321818Volledige weergave - Over dit boek
