4.38 A HISTORY OF RECENT CRUSTACEA 
by Henri Milne-Edwards, completed in 1840, though 
perhaps three times as valuable as Desmarest’s, was also 
three times as large. Since that date no work of similar 
scope has been carried out with any success in smaller 
compass, nor is it likely now that such a feat could: be 
accomplished. The Jinnee has escaped from the casket, 
and no magician can ever again reduce its gigantic expan- 
sion to occupy the narrow receptacle from which it 
issued.
