PKOCEEDINGS OF THE 



Tanne entomologique de I'Archipel Indo-Neerlandais,' containing 

 descriptions and figures of numerous species of Pentatomides. 



The Botanical works of general interest are chiefly those of 

 Professor Miquel, or published under his direction in the Annalea 

 Mnsaei Lugduno-Batavensis, now in its third folio volume. There 

 are here collected several partial monographs of plants belonging 

 chiefly to the Dutch East-Indian possessions. The greater part, 

 however, of the second and third volumes is occupied by Miquel's 

 own " Prolusio Florae Japonicse " (enumerations of the rich collections 

 of Japanese plants in the Leyden Herbarium, with descriptions of 

 new species and genera), forming a valuable repertory of materials 

 for a Plora Japonica, expounded by a botanist of great talent and 

 ability, but which would have been still more valuable had he be- 

 stoAved the necessary time to introduce more method and given us a 

 complete systematic enumeration of all that is known on that most 

 interesting flora, connected as it is with those of Asia, on the one 

 hand, and of North America, on the other. It is to be regretted also 

 that new genera and species have sometimes been hastily proposed 

 from insuflicient data. In the present day it is not only useless, but 

 detrimental to science to establish, for instance, new genera of Um- 

 belliferse without having seen the fruit. Dr. Miquel has, however, 

 added to his otherwise important labours an interesting essay on the 

 connexion of the flora of Japan with that of other countries. 



Belgium. 

 The only Memoranda I have of recent Belgian Biological papers 

 of general interest are v. Beneden's on the Polyps of the Belgian 

 coasts, and portions of M. d'Udekem's monograph of the Oligo- 

 chseta, in the Memoirs of the Belgian Academy of Sciences. 



Germany. 



Ernst Haeckel's * Generelle Morphologie der Organismen,' or Ge- 

 neral Morphology of Organisms, with the fuller title of ' General 

 Principles of the science of organic forms, mechanically established 

 according to the reformed descent- theory of Charles Darwin,' 2 vols. 

 8vo, Berlin, 1866, is a work displaying great ability, thought, and 

 philosophical method, and throwing considerable light on the gene- 

 ral connexion of organic beings, and the various points of view 

 from which they should be studied. If there may be perhaps in 

 some parts too much of German philosophical speculation and lengthi- 

 ness, it appears on the other hand to be founded on great general
