174 The Irish Naturalist. May, 



{Chrysophanus dispar), how too eager collectors exterminated it before the 

 middle of last century in its Fenland haunts, and how equally eager 

 collectors of to-day hunt for specimens — at five to ten guineas apiece — in 

 London auction rooms. The early stages of this grand insect are described 

 from specimens furnished by its Continental variety, rutilus. 



So we must conclude our survey of this volume. What we consider 

 to be defects and omissions we have pointed out, but the general im- 

 pression left on the mind of the reader is admiration for Mr. Tutt's 

 knowledge and industry, and gratitude for so rich a result from his 

 labours. The earnest entomologist will not fail to procure and stud}' 

 the work for himself, and he will look forward eagerly to the volumes 

 yet to come.

THE SCIENCE YEAR BOOK. 



The Science Year Book, with Astronomical, Ph}-sical, and Chemical 

 Tables, Summary of Progress in Science, Directory, Biographies, and 

 Diary for 1907. Edited by Major B. F. S. Baden-Powei,i„ F.R.A.S. 

 London : King, Sell, and Odling. Pp. 364, &c. Price 5s. net. 



The present issue is the third of this very useful annual, which can be 

 cordially recommended to all scientific workers as a handy book of 

 reference, and an excellent means of noting engagements and duties. 

 In the account of progress in science during 1906, five pages are devoted 

 to «' Zoology," "Natural History," and "Botany." "Zoology" seems 

 curiously restricted to works on the Mammalia. The biographical 

 directory of scientific men is interesting, but there are still some very 

 notable omissions — for example, A. Sedgwick and A. E. Shipley, of Cam- 

 bridge, and E. P. Culverwell, of Dublin. The directory of scientific 

 institutions also needs revision ; the staff of the Geological Survey of 

 Ireland appears as it was more than ten years ago. 



AIDS TO NATURE STUDY. 



Blackie's Nature Knowledge Diary. Compiled with Notes on 

 Nature Study, by W. Percival WESTEU,, F.R.H.S. Dublin and 

 London : Blackie and Son, Ltd. Pp. 64. 



This will prove a valuable help to teachers and scholars in observing 

 nature out of doors. There is a weather chart, on which the barometric 

 variations may be traced from day to day, a diary for notes on meteorology, 

 ornithology, entomology, botany, the farm and the garden, and space at 

 the end for a detailed index of entries to be arranged under the various 

 subjects. To encourage index-making, even in the youngest book-writers, 

 is praiseworthy Mr. Westell's introductory notes are brief and good.
