The Scottish Naturalist. 279 



In the department of Historical Geology the chief feature of the work is the 

 summaries of the climatic and geographical conditions which obtained during 

 ■each period. Without going into too minute details — which are rather too apt 

 to confuse a general reader — a broad view is given of the kinds of life which 

 successively existed, of the climate, and of the distribution of land and sea. 



The great aim of the author throughout the book has been to attain clearness 

 and to keep up the interest of the reader ; and we think we can congratulate 

 him on having succeeded in doing so. We should not omit to notice that 

 -which always adds to the attractiveness of a book — namely, the numerous 

 illustrations, about 400 in number. 



OUR INSECT ENEMIES. 

 By THEODORE WOOD. 



The Society for promoting Christian Knowledge has for many years done good 

 work in promoting the dissemination of greater facilities for gaining a know- 

 ledge of the objects that surround us on every side. By means of publishing 

 very useful and cheap small books upon various branches of sciencej the Society 

 has earned a claim to the goodwill of the community. 



The little work now under review is not unworthy of its predecessors ; and 

 though a good many books have been written to popularise in some measure 

 the very important subject of which it treats, this addition is likely to be of real 

 use in extending a truer understanding, and in raising the popular belief in 

 the value of a knowledge of our insect foes. A few more illustrations might 

 have aided the tyro in difficulties, even though there are numerous woodcuts 

 given in the work. The letterpress is interestingly written, and shows that Mr. 



Wood inherits the powers of his father, the well-known popular writer on 



Natural History. 



Those desirous to possess a good check list of British Marine Mollusca will 

 find their wishes met in a list just published by A. Somerville, B.S.c, 

 F.L. S. It follows closely Jeffrey's British Conchology, but has alterations 

 and additions to 1885. The varieties of each species are mentioned in smaller 

 type. Indenting the varietal names would facilitate reference to the list by 

 bringing the specific names into more prominence. The price of the list is 3d., 

 or 2s. 6d. per dozen, from A. Stenhouse, University, Glasgow.

I HAVE endeavoured in these records to bring together the 

 scattered notices of Scottish plants up to the end of 1885. 

 Of very many of the species mentioned below, specimens have
