ON PHOTOGRAPHS OF GEOLOGICAL INTEREST. 245 
Professor Armstrong, Mr. Cobbold, Dr. Matley, Dr. Flett, Dr. Abbott, 
and Mr. Smith. 
Mr. Welch points out that one print registered last year (3289), the 
cemented breccia of quartzite and slate at Howth, which contained bones 
of mammals and fishes with land and marine shells, is now the only record 
of an interesting geological fact, as the block has been washed away by 
the sea. 
The third and last issue of the published series of ‘ British Geological 
Photographs’ was sent out to subscribers in May of this year. The com- 
pletion and success of its first publication scheme marks an epoch in the 
history of the Committee and the fulfilment of a long-cherished desire of 
its founders. 
Since the first meeting in 1890 the desirability of publishing a selected 
series of geological photographs has been kept before the Committee, but 
it was only in 1893 and 1894 that publishers were approached on the 
subject. With one consent they recommended us to go elsewhere, and so 
the matter was allowed to slumber till the Dover meeting in 1899. In 
that year a Sub-Committee of selection, consisting of Professor Bonney 
(Chairman), Professor Watts (Secretary and Editor), Professor Garwood, 
Dr. Mill, Dr. Teall, and Mr. H. B. Woodward, was appointed, a self- 
supporting subscription scheme drawn up, and a preliminary selection of 
typical photographs made. One hundred and ninety-three subscribers 
undertook to support a series which was to consist of issues of twenty photo- 
graphs each year for three years. It was decided to issue the series in three 
forms—unmounted half-plate platinotypes, mounted platinotypes, and 
lantern slides—and each issue was to be accompanied by descriptive 
letterpress. 
Various unforeseen circumstances delayed the first issue, but it saw 
the light in September 1902 ; issue ii. followed in July 1903, and the final 
issue in May 1904. The actual series, as published, comprised seventy- 
two photographs, fifty-one being standard half-plates, ten quarter-plates, 
and eleven whole-plates, and an equal number of lantern slides. The sub- 
jects ranged over most of the ordinary geologica] phenomena, the chief rock 
formations, and many of the more important British localities. The nega- 
tives were lent by thirty-four photographers, and a descriptive pamphlet 
of forty-two pages was written by thirty-four contributors, amongst whom 
are many of the most famous of contemporary British geologists. To 
both geologists and photographers the Committee express their warmest 
thanks. 
The estimates on which the Sub-Committee worked proved to have 
been well founded, and the annexed balance-sheet gives an account of all 
receipts and expenditure to date. It shows a balance in favour of the 
Committee of £95 13s. 2d., and a prospective profit of over £130 when 
all outstanding accounts shall have been paid. 
The balance-sheet, however, does not make one important point clear. 
Eight whole-plate platinotypes and twelve slides beyond the number agreed 
upon have been issued to subscribers. It is estimated that these addi- 
tional photographs have cost £105. If this be added to the balance in 
hand the total profit has been £235, of which one-half has been returned 
to the subscribers and the other half retained by the Committee for the 
purpose of carrying on the work for which it was originally established by 
the Association.
