282 TAXIDERMY AND MODELLING 



This extremely easy process — given by Mr. Goodchild^ — 

 consists in beating tinfoil with a brush, etc., on to fossils, and 

 thus getting a clicM. As a copy, the result is satisfactory, yet 

 it must be pointed out that, even when backed as directed, it 

 dents with the slightest pressure, and although it has been well 

 tried in the Leicester Museum, and certain improvements made 

 upon it, yet it cannot, of course, compare with any of the paper 

 processes described in this chapter.
