7. R. Spruce, Hepaticce Amazonicce et Andinaz. — This elabo- 

 rate monograph fills the two parts of the fifteenth volume of the 

 Transactions and Proceedings of the Botanical Society of Edin- 

 burgh (1884-5), — nearly 600 pages of letter press, including a full 

 index of genera and species, and 22 neat lithographic plates. All 

 that remains to the completion of Mr. Spruce's indefatigable 

 labors is the promised introduction, relating to " the physical fea- 

 tures of the regions explored, and their connection with the vege- 

 tation, especially the hepatic vegetation, with critical remarks on 

 certain of the genera and species." The author's illness has pre- 

 vented the appearance of this in the present volume. We join 

 in the hope that he may be able to present it in a supplement.
