CALOTYPE (καλος and τύπος), the name given by Mr
H. Fox Talbot to his photogenic process for obtaining copies
of natural objects and pictures; in which paper prepared in a
particular manner is used, instead of the silvered plates em-
ployed for that purpose by M. Daguerre. It is also some-
times called Talbotype, in honour of the inventor. See
