ON PHOTOGRAPHS OF GEOLOGICAL INTEREST. 533 



secure duplicates. The Secretary has been elected a member of Council of 

 the Association. 



The photographs received during the year are now being mounted, 

 and, after exhibition at Bristol, will be bound up with the rest of the 

 collection at the Museum of Practical Geology, 28 Jermyn Street, where 

 they may always be referred to on application to the Librarian. The 

 entire collection is arranged topographically under counties and their 

 natural divisions, so that reference is as easy as circumstances will permit. 

 A catalogue arranged under counties is kept at Jermyn Street, and a card 

 catalogue is maintained up to date as new photographs are received. 



Mention was made in the Report for 1897 of the formation of a dupli- 

 cate loan collection of prints and slides. This has now been arranged 

 <^eologically and made available for circulation. The additions made 

 during the year — forty-four prints and fourteen slides — are acknowledged 

 in List II. A descriptive account of the slides has been printed by the 

 Secretary, and sent to those societies which have borrowed them for 

 exhibition. This description has also proved useful as labels for such 

 prints as deal with subjects similar to the slides. 



The duplicate collection has been lent to the Dublin Field Club, the 

 Belfast Field Club, the Birmingham Natural History and Philosophical 

 Society, and to the Photographic Exhibition at the Crystal Pa,lace. 

 Applications for the loan of this collection for the forthcoming winter 

 should be made to the Secretary as soon as possible. The only expense 

 to the borrowing Societies is the carriage (one way only when that can be 

 arranged) and the making good of any damage to prints or slides. 



A list of donors to this collection is appended to List II., and to them 

 the Committee express their thanks. 



The photographs in this selected series are naturally of the kind which 

 would be most useful to those who wish to obtain typical examples for 

 teaching purposes or for exhibition in illustration of papers ; and there- 

 fore, whenever it has been possible to arrange it, an address is given 

 whence prints or slides may be purchased. But it must be distinctly 

 understood that the Committee can undertake no responsibility or corre- 

 spondence in this matter. All information possible will be circulated 

 with the collection, and there the Committee's work must end ; would-be 

 purchasers must make their own arrangements with photographers, in 

 whom exclusively the copyright remains vested. 



It has been decided to discontinue issuing the list of jmhlished photo- 

 (/raphs, as no important service appears to be rendered by it, but a careful 

 record will be kept of all photographs which have been used to illustrate 

 papers or books. The Committee are indebted to the editors of the 

 ' Quarterly Journal of the Geological Society ' and of the ' Proceedings of 

 the Geologists Association' for help rendered in connexion with this 

 branch of the work. 



The Secretary will be grateful if the donors of photographs will 

 kindly look through the parts of the lists in which they are interested 

 and will notify to him any slips in the spelling of proper names, in the 

 geographical or geological descriptions, or mistakes of any other kind 

 which occur in the Report. 



The Committee ask for their reappointment with a small grant to 

 defray some of the expenses connected with the mounting, storing, and 

 collection of the photographs, and for printing such circulars and forms as 

 are necessary for carrying on the work.
