In looking through the above our pleasure increased with each 

 successive issue of the " Studies " — a title which they richly 

 merit. The whole work is, in our opinion, most studiously,

 tion possible to be obtained on the subjects treated, will, we 

 think, be found here. We cordially recommend our readers to 

 subscribe to these studies.
