It is interesting to observe the gradation from the coarse 

 tube of the animals of this genus through all the varieties 

 of more regular form observable in other mollusca, and in 

 manv insects, to the finished cell of the bee. Dr. Steffens is 

 of opinion that these different figures are caused by the cry- 

 stallization of the exuded matter. The reader is referred for 

 the proofs of this opinion to his BeitrJigc zur Kenntniss der 

 innern Naturgeschichte der Erdc.
