 metallic and allied compounds ; Alkaloids ; Protoids , Coloured 

 compounds ; Operations in Organic Chemistry ; Analytical 

 Chemistry ; Theoretical and Physical Chemistry, and Physio-

Notes on the manner in which the various entries are to be 

 catalogued are given, and as in the case of " Theoretical and 

 Physical Chemistry," the following sub-heads are given : 



General ; Conditions and laws of chemical change ; Mass 

 properties ; Mechanical properties ; Thermal properties ; Elec- 

 trical and Magnetic properties ; Optical properties ; Photo- 

 Chemistry. 



Such a volume is indispensable to the practical chemist of to- 

 day in whatever department of that comprehensive science he 

 happens to be interested. A list of the journals which publish 

 chemical papers, etc., is appended at the end of the volume as 

 well as a complete Index which adds greatly to its value and 

 usefulness.

P.irt I. This Catalogue of the writings on Botany during the 

 year igoi contains 378 pages of text and includes, like all the 

 catalogues of the International Catalogue of Scientific Literature,

 languages, [b.) An authors' catalogue, (c.) A subject catalogue. 

 The subject catalogue is divided into sections. As this is the first 

 part of the first volume pulished by the Royal Society of London, 

 a number of notes on the methods employed in cataloguing the 

 Botanical works of the year and subsequent years are presented, 

 and are of special value. It shows clearly how very complete the 

 scheme of classificati n has been drawn. 



The primary divisions adopted correspond to the recognised 

 branches of the science of Botany. Both recent and fossil Botany 

 is dealt with in this volume. The stratigraphical grouping of 

 entries relating to fossils will, of course, be left exclusively to Palae- 

 ontology. Besides works referring to the Philosophy of Botany, 

 there are also those relating to History of that science and Bio-
