Notes and Comments. 345 
State grant made by Great Britain toward the expenses of 
the publications of learned societies is limited to the sum of 
£1,000 annually to the Royal Society, several times this amount 
is expended each year upon stationery alone used by members 
of the House of Commons.’ In this connection may we suggest 
to Professor Gregory that ‘ Nature’ never did betray the heart 
that loved her, and we trust he has found this to be so! 
There is no doubt that after the present crisis the claims of the 
scientific man will be much more appreciated. In many ways 
he has already demonstrated his worth. And _ Professor 
Gregory’s book will, we hope, do much towards voicing those 
claims. 
INVESTIGATION OF RIVERS. 
In view of the suggested work in connection with Yorkshire 
Rivers being undertaken by the members of the Yorkshire 
Geological Society, we should like to draw attention to a 
valuable Final Report on the Investigation of Rivers, by 
Aubrey Strahan, N. F. MacKenzie, H. R. Mill and J. S. Owens, 
published by the Royal Geographical Society, 94 pages, price 
3s. 6d. The report deals with the Severn basin and its vicinity, 
and is divided under the following headings :—Introduction, 
Report on Severn Discharge and Rainfall in the Basin; The 
Measurements of Discharges; Curves showing Rainfall and 
Discharge ; Report of the Average Annual Rainfall of the 
Exe Valley ; Report on the Daily Rainfall of the Exe Valley 
during the years 1907-1912; On the Area of each Basin and 
the Elevation of different parts of it; Report on Suspended 
and Dissolved Matter in the Exe, Creedy, Severn and Medway ; 
Appendix—Table of Discharge Coefficients. There are many 
valuable charts and tables accompanying the report, which 
should serve as a model for other areas.

Three Rocklings and a Sea-Bullhead,’ by H. N. Milligan; ‘Notes on 
Inability of Natural Selection to explain certain steps in the Evolution

In The Entomologist’s Record, in 1907, Mr. H. Donisthorpe described 
Cis dentatus Mellie, as a new British insect. In the same Journal for 
July and August, just received, he states that the species is not dentatus 
but an aberration of C. alni. In the same Journal Mr. R. S. Bagnall 
describes some new British Plant Galls from the Northumberland and 
Durham area.
