are in truth volcanic, not to mention the certainty that the gravi- 

 tational conditions under which they originated must have been very 

 different from those encountered on the face of the earth. 



A large part of the paper is devoted to the classification and 

 ■discussion of volcanoes on the principles outlined above. There are 

 throughout abundant and well-executed illustrations.

IV. — Annual Repokt of Bkitish Museum. 



British Museum (Natural History). — Reference is made in the 

 British Museum Return for the year 1911 (H.M. Stationery Office, 

 1912) to the use of the site on the north of the JS^atural History 

 Museum, and the following paragraphs are of considerable interest : — 



" As a result of further correspondence and of several conferences 

 between representatives of the Departments concerned, a settlement 

 lias been arrived at, under the terms of which the boundary of the 

 Natural History Museum as adjusted in 1899 has been secured to 

 the Trustees. By the settlement the demolition of the existing 

 Spirit Building has been avoided, and accommodation for the Geological 

 Survey and the collections at present in Jermyn Street will be 

 provided on ground south of the boundary line of 1899. The buildings 

 for the Survey offices and the collections (while communicating witli 

 the Science Museum) will be in connection with and form a part 

 structurally of the eastward extension of the Natural History Museum, 

 and will be so arranged as to fit that extension when it is eventually 

 built. A Lecture Theatre, which will be under the control of the 

 Trustees but available for joint use by both Museums, forms part of 

 the scheme." 



" The Trustees in assenting to provide this accommodation for the 

 [stratigraphically arranged] Geological Survey collections believe 

 that the arrangement will be of great advantage to students and 

 others interested, since these collections will thus be continuous with 

 the- part of the Natural History Museum in which are arranged the 

 Systematic Palseontological and Mineralogical collections." 



We note also that this year the Swiney Lectures are to be delivered 

 in December and January, instead of in November, and Dr. Jehu's 

 subject is to be " The Record of Life as revealed in the Ptocks ". 



V. — Cambridge County Geographies. — Two more volumes have 

 reached us. One on Lanarkshire, by Mr. P. Mort (1910), has been 

 unfortunately overlooked. It contains good descriptions of the 

 physical features, with views of the Leadhills, the Falls of the Clyde, and 

 a diagram illustrating the pre-Glacial channels of the river. There is 

 a brief account of the geology, more particularly in reference to the 

 Coal-measures, and illustrated by a view of fossil trees at Whiteinch, 

 near Glasgow. The glacial drifts are described, but no reference is 

 made to the fossil shells of the Clyde Valley Beds. Lead-mines, the 

 gold of Clydesdale, the coal and oil-shale, are duly mentioned in the 

 section on " Mines and Minerals" ; and we are glad to see the name 

 of A. C. Ramsay in "the Roll of Honour".
