INDUSTRIAL PROGRESS DURING THE YEAR 1872. Htf 



The Radiates have had several unusually important works 

 devoted to their illustration, the first part of Alexander Agas- 

 siz's long-looked-for work on the Echinoids having appeared, 

 Allmann's great work on the Gymnoblastic Hydroids having 

 been completed, and a work by Dana on the Corals and Cor- 

 al Formations, and one by Kulliker on the Alcyonaria, hav- 

 ing been published. 



The Protozoa, as represented by the Sponges, have been 

 the objects of study by Bowerbank, Carter, H. J. Clark, Gray, 

 and Kent; and one group especially has been finely illustrated 

 in an excellent monograph published by Hackel. The Fora- 

 minifera have been the subject of articles by Parker and 

 Jones, and the Vorticellce have been further elucidated by 

 Greef. 



In Botany, the most important work that has appeared in 

 this country is the " Genera Lichenum" of Professor E. Tuck- 

 erman. Dr. Gray, besides his address at Dubuque upon the 

 origin of the North American flora, has published, in the Pro- 

 ceedings of the American Academy, notes on several genera 

 of Labiatce, and an enumeration of an interesting collection 

 of Oregon plants made by Elihu Hall. Leo Lesquereux has 

 given a report on Fossil Botany, supplementary to the Fifth 

 Annual Report of the United States Geological Survey of the 

 Territories. The report, also, of C. H. Peck to the Regents 

 of the New York State University is a valuable contribution 

 to cryptogamic botany. 



In England, the first volume of a " Flora of British India," 

 by J. D. Hooker, has appeared, and the second volume of 

 Bentham and Hooker's " Genera Plantarum" is in course of 

 publication. M. A. Cooke, whose recent work on Fungi is 

 now the best authority on that subject for American species, 

 has undertaken a monthly journal, the " Grevillea" devoted 

 to cryptogamic botany. On the Continent, Decaisne has com- 

 pleted an extended monograph of the genus Pyrus ; Bois- 

 sier has issued a second volume of his "Flora Orientalis," 

 a work which is to be a Flora for all Western Asia, from 

 Greece and Egypt to the borders of India ; Baillon's " His- 

 toire des Plantes" has been continued, as also the "Flora Bra- 

 siliensis," edited by Professor Eichler since Martius's death. 

 Pritzel has nearly completed a revised edition of the " The- 

 saurus Literatura) Botanical ;" Dr. Pfeifter lias commenced a
