DIALOGUE VII. 
TRANSFORMATION OF THE CATERPILLAR 
TO THE PUPA. NYMPHS. DURATION OF 
THE PUPA. PLACE OF CONCEALMENT. 
LUCY, How fortunate I am, mamma, 
that nothing has happened to prevent 
your going on with the account of the 
pupa, as you promised. 
Mother, As I shall not be able to 
stay long with you to-day, we will be- 
gin at once. When the caterpillar has 
lived its destined length of time, it ceases 
to eat; and, creeping to a place of shelter 
and security, it becomes dull, seems to 
dislike moving, and after passing some 
days in this sluggish state, it works out of 
the old skin, which opens along the 
back.
