University College, London, where Professor Garwood has offered to 

 exhibit and store them. Some few duplicates are still in the Secretary's 

 hands for purposes of comparison. The Lamellibranchs and Brachiopoda 

 from Eccup, collected some years ago, have been determined and sent to 

 University College. Very few museums, if any, possess specimens of the 

 Pendleside fauna, and practically no fossils from the alternating limestones 

 and shales of the Yoredale phase of the Carboniferous Limestone are 

 exposed. 



The thanks of the Committee are due to Mr. 11. Kidston, F.R.S,, 

 Dr. A. H. Foord, and Dr. AVellburn for work done on the collections, 

 and for furnishing reports which are incorporated herein, and to ]\Ir. J. 

 Dunn for allowing me to make use of his collections in compiling the 

 fauna of the Redesdale and Four Laws Limestone ; to Mr. J. Barker 

 for similar help in Weardale. 



The balance of 51. left over from last year has been spent, together 

 with the greater part of the grant of lu/. made at the last meeting, 

 leaving only a few shillings balance. It is to be hoped that a liberal 

 grant will again be forthcoming. The Secretary proposes that detailed 

 work be commenced on the various limestone and shales of the western 

 escarpment of the Pennine series, together with an examination of the 

 quarries in the lower part of the Limestone Massif in Derbyshire, to 

 ascertain if any fossils appear to be restricted to certain beds or horizons. 

 The Secretary also hopes to obtain an accurate list of the Culm fauna 

 of Devonshire, the similarity of the Pendleside and Culm faunas being 

 most striking.

Plate II. 



The Committee is carrying out tlie investigation in conjunction with a 

 committee of the Yorkshire Geological and Polytechnic Society. 



On referring to the last report of this committee it will be seen that 

 on September 5, 1901, three quarters of a pound of fluorescein was put 

 into the water flowing down Long Churn, near Alum Pot, at 4 p.m., and 

 that a further quantity of three quarters of a pound was introduced at 

 5.30 P.M. on the same day. At the time of writing the last report the 

 outflow of this had not been observed ; but it has since been learned that 

 it issued from Turn Dub, on the opposite side of the River Ribble, and 

 close to the bank of that stream, on September 1 7. The water therefore 

 took twelve days to accomplish a journey of H mile. 



The extreme slowness of the flow is partly' to be accounted for by the 

 dry weather which then prevailed ; but when it is taken into considera- 

 tion that the water of Long Churn plunges down a very steep fall into 

 Aluni Pot, the total depth of which is some 300 feet, the gradient of the 

 remainder of the stream is considerably reduced.
