PHOTOGRAPHS OF GEOLOGICAL INTEREST 307 
pillow lavas of Newborough, Anglesey, taken by Mr. J. Trevor Owen, and 
Mr. J. Ranson some from the Isle of Man and a group illustrating the 
Brimham rocks, Harrogate. The Hon. Secretary contributes sets from 
Devon, Durham, Northumberland, the Ardnamurchan peninsula, and the 
North of Scotland. 
The transfer of H.M. Geological Survey Office and Museum from 
Jermyn Street to South Kensington has involved a corresponding transfer 
of the Committee’s collection of photographs, which is now housed in the 
new Survey Library, and is far more easy to refer to than was the case at 
Jermyn Street. 
During the period of transfer the collection, through the kindness of 
Prof. P. G. H. Boswell, was housed at the Imperial College, South 
Kensington, and the opportunity was taken thoroughly to overhaul it and 
the card catalogue. The Committee are greatly indebted to Prof. Watts 
for the help he gave in this matter and in particular for the large amount 
of time he devoted to checking the card catalogue. 
Some years ago Mr. F. W. Reader presented to the Committee the large 
collection of geological negatives made by his late brother, Mr. T. W. 
Reader. A second valuable collection of negatives has since been received 
as a gift from Mr. C. J. Watson. Executors may sometimes be glad to 
know that the Committee is glad to accept any collection of geological 
negatives. In past times several important collections have unfortunately 
been destroyed, probably through executors being unaware of their 
importance. 
In the previous report (London, 1931) the fact is mentioned that a new 
(second) series of geological photographs (issues D and E) was ready. Although 
the publication of this new series has not resulted in any financial loss to the 
Committee it has scarcely justified itself, the demand being vastly less than 
in the case of the first series (issues A, B, C), brought out by Prof. Watts. 
Of the second series there were sold to the end of 1934: 
Issue D prints 17 sets, lantern slides 25 sets. 
Issue E_ prints 17 sets, lantern slides 26 sets. 
The number contrasts lamentably with that of the 193 subscribers (see 
1904 report) who undertook to support the first series. The unfortunate 
result was not due to neglect of advertising. 
An attempt was made to extend the knowledge of the Committee’s work 
among Geographers by the publication in 1932 of an article in Geography, 
and by an exhibition at the meeting of the Museums Association in Bristol 
in 1934. At the latter meeting the following circular was issued altering 
the conditions of sale of the photographs published by the Committee : 
“Hitherto these have been sold only in sets. This practice has probably 
checked the sale, as many of the subjects included, though interesting to 
geologists, do not appeal to geographers. It is proposed therefore to 
allow purchasers to select from the whole series of published photographs 
those which interest them. Such subjects may be obtained from the Hon. 
Secretary at the following rates : 
Prints, half plate, unmounted ; . 15s. a dozen
