54 SUMMARY OF CURRENT RESEARCHES RELATING TO 



Analytical Keys to the Hepatics.* — Ch. Lacouture publishes a 

 series of synoptical tables exhibiting the leading characters of the tribes, 

 genera and species of the hepatics of France. These tables are applic- 

 able to the majority of our own species, and as they are very clearly 

 arranged and illustrated with over 200 figures in the text, the deter- 

 mination of species is much simplified.
