Henry Bradbury, Esq. M.R.I. 

 On Nature-Printing. 



The Art of Nature-Printing is a method of producing impressions 

 of plants and other natural objects, in a manner so truthful that 

 only a close inspection reveals the fact of their being copies. So 

 distinctly sensible to the touch are the impressions, that it is difficult 

 to persuade those unacquainted with the manipulation, that they are 

 the production of the printing-press. The process, in its applica- 

 tion to the reproduction of botanical subjects, represents the size, 

 form, and colour of the plant, and all its most minute details, even 

 to the smallest fibre of the roots. 



The distinguishing feature of the process, compared with other 

 modes of producing engraved surfaces for printing purposes, con- 

 sists, firstly, in impressing natural objects — such as plants, mosses, 

 seaweeds, feathers, and embroideries — into plates of metal, causing 

 as it were the objects to engrave themselves by pressure ; and 

 secondly, in being able to take such casts or copies of the impressed 

 plates as can be printed from -at the ordinary copperplate-press.
