the date of the appearance of this issue of Torreya. The work 

 makes a volume of 1,382 pages, of large octavo size, and includes 

 descriptions of 6,364 species. The published price is $3.60. It

Part 2 of Volume 8 of the Contributions from the National 

 Herbarium consists of a paper on the " Economic Plants of Porto 

 Rico " by O. F. Cook and G. N. Collins. The plants are 

 arranged alphabetically under Latin, Spanish, and English names 

 in a single series. The more important are discussed at length 

 and many are illustrated from photographs. The work will 

 prove of much value to those interested in the common and use- 

 ful plants, not only of Porto Rico, but of tropical America in 

 general.
