ON THE PREPARATION OF A GEOLOGICAL MAP OF EUROPE. 241 



remains of mammoth, bear, horse, reindeer, and other animals, remains ia 

 great part unexplored since the excavations of our late lamented friend 

 Professor A. Leith Adams in 1875. He was then prevented from prose- 

 cuting his work further by the danger of the impending roof coming away 

 in fragments, the rock being full of horizontal splits, so that layers of 

 stone are ready to fall if disturbed from beneath. Professor Leith Adams 

 was anxious to resume the exploration of this great cavern, which has 

 been so fruitful in Pleistocene mammalia, and stated it as his opinion that 

 the superincumbent rock should first be wholly removed for a distance of 

 fifty feet along the face of the cliff, taking the present mouth of the cave 

 as the centre, and as far in as Cullen's Chamber might extend. The cliff 

 is over twenty feet in height, so that such an undertaking would involve 

 considerable outlay, including compensation to the occupier of the ground. 

 If, however, your Committee could undertake to have the work quarried 

 at sixpence a cartload, the stone thus obtained might be sufficient recom- 

 pense for the injury to land and fences. A very large quantity of stone 

 would have to be removed, which could be done during the winter 

 months, leaving the floor of the cavern open for excavation before next 

 summer. It is difficult to estimate the probable expenses of this work. 

 To do it effectively the cave should be properly opened up by the total 

 removal of its roof. Professor Leith Adams expended 401. on the portion 

 that he excavated in 1875, without having to remove any of the roof, as 

 his operations were conducted near the mouth. A sum of 50Z. seems to 

 be required for the work now proposed.

Report of the Committee, consisting of Sir A. C. Ramsay, Professor 

 J. Prestwich, Professor T. McK. Hughes, and Mr. W. Topley, 

 appointed to assist in the preparation of an International 

 Geological Map of Europe. Drawn up hy Mr. W. Topley 

 {SecretaryX 



Since the appointment of the Committee last year considerable progress 

 has been made with the Geological Map of Europe. The International 

 Geological Congress met at Bologna on September 26 last. Two 

 members of this Committee, Professor Hughes and the Secretary, 

 attended the meeting. The discussions extended over five days, but it is 

 only with those immediately referring to the Map that this Committee is 

 concerned. 



The Congress resolved to prepare and publish a Geological Map of 

 Europe, with so much of Asia and Africa as comes within the border : 

 the map to be published at Berlin on the scale of 1 : 1,500,000 (about 

 23 miles to the inch). A Committee to carry out the work was appointed 

 as follows : — 



MM. Beyrich and Hauchecorne for Germany (Directors of the Map). 



M. Daubree for France. 



M. De Moeller for Russia. 



M. Giordano for Italy.
