304 KEPORT— 1897. 



such numbers in previous lists must now be finally cancelled, as the 

 Secretary has failed to recover them, or else they have never actually 

 been in the collection. With some of these numbers it will be noticed 

 that no photograph has ever been associated. 



The Committee desire to express their warmest thanks to those donors 

 who have so kindly enabled them to bring the collection into a perfect 

 state up to date. The following names should be mentioned with thanks : 

 Mr. Stewart, Mr. Detieux, Mr. Bingley, Miss Andrews, Dr. Stolterfoth, 

 Mr. Brook, and Mr. Welch. 



List No. 2 comprises lost photographs which have been renewed, and 

 List No. 3 is necessitated by the slight confusion which has occurred in 

 connection with the supply of missing photographs and the filling of gaps. 

 Here, again, many of the original donors have given help ; their names 

 are mentioned with thanks in this list. 



Certain Scientific Societies have been in the habit of issuing specially 

 taken photographs to their members, and several of them have sent sets 

 to the Committee in past time. An effort has been made to make these 

 sets more perfect, and the Societies in question have given ready help. 

 The Yorkshire Geological and Polytechnic Society and the Liverpool 

 Geological Society, for example, have overhauled the list and promised to 

 contribute such of their prints as are still to be got to complete our set. 



The Secretary will be very pleased to receive help from geologists in 

 annexing fuller and more accurate descriptions of the geological features 

 to the photographs, in order that they may become of the utmost use as a 

 work of reference. He will also welcome corrections and additional 

 information from those who inspect the collection. Several persons 

 anxious to obtain examples to illustrate both geological and geographical 

 phenomena have visited the collection, and to more than one it has been 

 found of much use for the purpose ; as it becomes larger and more repre- 

 sentative it must become increasingly important and useful in this respect. 

 The Committee will welcome suggestions as to the best method by which 

 eventually it may be possible to enable those interested in such things to 

 obtain reproductions or prints without imposing a strain on the time and 

 good-nature of willing contributors. 



It has long been evident that, while it is essential that the main 

 collection should be permanently lodged at a central place where it can be 

 used for reference, it would be a great advantage if some portion of 

 it could be allowed to circulate amongst geological and photographic 

 Societies, in order that the kind of work necessary and its utility might 

 be made obvious to those bodies and persons likely to take it in hand. 

 For this purpose the best thing appeared to be the formation of a duplicate 

 loan collection selected from the best and most typical photographs in the 

 main collection and arranged geologically. A few duplicates found in the 

 collection have been set aside for this purpose, and an appeal has been 

 made to contributors to give prints or slides of those photographs most 

 suitable for the purpose. To this appeal there has been a most liberal 

 response, and a loan collection has been inaugurated. It now numbers 

 219 prints and 81 slides, of which a separate classified list is annexed 

 (No. 4). A description will be written to serve as an account of the 

 slides or as labels for the prints, and the two parts of the loan collection 

 will be ready for circulation amongst such Societies and Clubs as are pre- 

 pared to pay the expenses of packing and carriage, and to make good any
