610 Reviews — Geological Photographs. 



They include examples from Antrim and Cork, the glacial and 

 associated deposits of Down and Dublin, and phenomena connected 

 with limestones and caves in Sligo. One of the photographs is both 

 botanical and geological, for it shows the formation of tufa in 

 a limestone district through the agency of colonies of various mosses. 



To all the gentlemen named the Committee tender their best 

 thanks, as well as to the following, who have contributed less in 

 amount, it is true, but individual examples or series of high value : 

 Mr. Epps, Mr. G. T. Atchison, Mr. Hopkinson, Messrs. Abley & 

 GrifHth, Mr. Hodson, Professor Armstrong, Mr. Cobbold, Dr. Matley, 

 Dr. Flett, Dr. Abbott, and Mr. Smith. 



Mr. Welch points out that one print registered last year (3,289), 

 the cemented breccia of quartzite and slate at Howth, which con- 

 tained 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 completion 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 

 application elsewhere, and so the matter was allowed to slumber 

 till the Dover meeting in 1899. In this 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 sub- 

 scription 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 photographs 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 subjects ranged over most of the 

 ordinary geological phenomena, the chief rock formations, and many 

 of the more important British localities. The negatives 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.
