■XVIII V SCIENCE PROGRESS. 



Original illustrations such as figs. 5 and 17 and copies such as figs. 

 12, 18 and 234, are not to be beaten; but we would have more of 

 them. Paper and printing leave nothing to be desired ; and, as for 

 style, the portions of the work dealing with the life-history of the 

 Tematoda and the fissiparous process in the Polychaeta read like a 

 romance. The Editors have this time kept their forces well in hand, 

 and with co-authors and publishers have executed their work in a 

 manner worthy a new departure by a great nation.
