278 TAXIDERMY AND MODELLING 



they appear to be sufficiently waterproof to resist ordinary 

 moisture. 



This has been discovered to be a sine gud non, some fishes, 

 etc., made of Formula 95 composition a year ago, and left 

 uncoloured but filled in with paper, having been placed in a 

 damp situation, collapsed in greater part ; on the removal of 

 the paper filling, however, and the substitution of sawdust, they 

 were restored to their proper shapes in all but one. or two bad 

 examples, and, having been painted, inside thickly, and outside 

 very thinly, with quickly -drying flake white, they are now 

 efficiently protected thereby. Those executed at the same 

 time, and coloured, underwent no change. 



The weights of various objects modelled in the glue com- 

 positions. Formulae 95 and 96, are given below: — 



A roach of the original weight of 8 oz. was cast solid, and 

 weighed just double, i.e. i lb. By paring and hollowing out, 

 1 1 oz. was removed, thus leaving the model 5 oz. only in weight 

 — a gain of 3 oz. on the original. 



The same fish cast hollow weighed 4 oz., and, when filled 

 with wadding and backed with cardboard, but 6 oz. 



A perch of the original weight of 2 lbs. S oz. was but 7 oz., 

 and, when backed and finished, 1 1 oz. 



A bream of 5 lbs. S oz. weighed, when modelled, i^ lbs., 

 and, when backed and finished, 2 lbs. 



A ceratodus of 1 5 lbs. original weight weighed, when cast, 

 2 lbs. 10 oz., and, when backed and finished, 3^ lbs. 



A carp of 12 lbs. 10 oz. was modelled to a weight of i lb. 

 10 oz., and, when backed and finished, was 2 lbs. 13 oz. 



A ringed snake cast solid weighed, when completed, 8^ oz. 



A large rock snake of some considerable weight, when cast 

 hollow, weighed but 2 lbs. 



Some of these, the ceratodus for instance, were not cast 

 quite so thinly as others.
