264 TAXIDERMY AND MODELLING 



The model is then affixed by screws passing from the back of 

 the tablet into the fixed body-board, and, where the edges of 

 the model do not quite touch, they are made up with one of 

 the pulps, wax-, or other compositions. It may be, but seldom 

 is, necessary to fill in large fishes made with very thin pulp. 

 In this event, a square hole is cut in the body-board, through 

 which, after it is fixed and dry, sawdust or wadding is intro- 

 duced, and the hole is then closed again. 



The latest addition to the pulps used in the Leicester 

 Museum is one which has given the very best results in quick- 

 ness of making, toughness, and extreme definition ; by it very 

 fine models of fairly large fishes, fossils, and other objects have 

 been made with gratifying success, and its lightness is so 

 extreme that it may be calculated, in almost every instance, as 

 being half an ounce in the model to every pound weight in the 

 original. For instance, a 12 lb. 9 oz. carp weighed but six 

 ounces ; a 5 lb. 5 oz. bream three ounces, and a 6\ lb. block 

 of stone, on which were ammonites, four ounces, after the thick- 

 ness of the model had been made up on its sides and under 

 surface to resemble the original stone.

The above should be well beaten in a metal mortar until 

 reduced to a fine pulp, and afterwards worked, a small portion 

 at a time, by a muUer upon a stone slab, or by a strong spatula 

 upon a piece of thick glass, until it becomes as a thoroughly 

 homogeneous paste without showing knobs or traces of un- 

 worked paper. When squeezed between the fingers it should not 

 be " short," nor break up easily, but should be tough and closely 

 adherent.
