CYANOTYPE--ENERGIATYPE--CHROMATYPE--ANTHOTYPE--AMPHITYPE AND "CRAYON
DAGUERREOTYPE."
The several processes enumerated at the head of this chapter, are all
discoveries of English philosophers, with the exception of the third
and last named. Anthotype was first attempted by M. Ponton a French
savan, although it was reserved to Mr. Hunt to bring the process to its
present state. The "Crayon Daguerreotype" is an improvement made by J.
A Whipple, Esq., of Boston.
