470 THE ZOOLOGIST. 
Scotland, and which was responded to in a very liberal spirit, he 
has been enabled to furnish some interesting particulars con- 
cerning the gradual increase and present distribution of the 
species, ‘The evidence thus collected is arranged methodically 
and clearly, while a small map exhibits at a glance the districts 
(coloured red) wherein the Capercaillie may now be found. 
The author’s concluding remarks on the damage which the 
bird does to young trees by feeding on their growing shoots, and 
in its alleged hostility to the Black Grouse, are not the least 
valuable portions of his essay. 
The Spiders of Dorset; with an Appendix containing short 
Deszriptions of those British Species not yet found in Dorset- 
shire. By the Rey. Ocravius Pickarp CampripGe, M.A.,,

future number we shall hope to deal with it more fully, and give 
some extracts from the pages of our author on a subject which 
hitherto seems to have attracted but little attention amongst 
naturalists. In the meantime it must suffice if we direct attention 
to the appearance of this recently-published volume, and recom- 
mend to our readers the perusal of the ‘‘ Introduction”: in 
its entirety. It furnishes an amount of information, clearly and

thirds of those as yet known to be British, and as an appendix
