packed under each other as closely as possible, are made to 
slide out until they remain in the fully developed wing like 
the tiles of a roof. He exhibited preserved specimens of the 
Currant moth and the Tiger moth, with the wings both in 
their small and in their expanded state, also a coloured 
sketch of one of them, and it was seen that in the unexpanded 
state the wings lie flat without any folding, and all their 
markings are a correct representation in miniature of what 
they ultimately become.
