By Thomas Sheppard, F.G.S. 



ON visiting Brougli a short time ago I noticed a small section had 

 been made on the western slope of Mill Hill, about twenty or 

 thirty feet below the top. The excavation is made in soft white 

 sand, which is very ferruginous in places. Beds of hard sandstone, 

 varying in thickness from one to three inches, traverse it in the 

 upper part of the section. These beds of sandstone are practically 

 horizontal, and contain casts of Belenmites Owenii, Gryphcea hilobata, 

 Trigonia, and other charactei'istic Kellaways Rock fossils. In not 

 a single instance was a portion of a shell remaining, the whole of 

 the calcite having been dissolved away. There is only a thin 

 covering of soil ; and this contains numerous pebbles of doubtful 

 origin, and some pieces of Roman pottery. 



The excavated material is sent to Leeds, where it is used by an 

 engineering firm for moulding. 



On examining the pit I noticed a piece of very ferruginous 

 material. It was of rather peculiar shape, however, and on picking 

 up further pieces it became evident that they were small fragments 

 of bone. They had been thrown on a heap on one side, aud such 

 bones as were found had to be picked from this heap ; consequently 

 their exact horizon could not be determined. Subsequent visits 

 were the means of finding still further specimens, chiefly whole and 

 broken vertebra3, pieces of ribs, etc. On one of these occasions 

 a vertebra was noticed protruding from the quarry face, at a depth 

 of about seven feet ; this was in close proximity to the heap from 

 which the other remains had been obtained. This vertebra was 

 extracted, and several others were found on the same level, fitting 

 close together. These vertebrce were nearly circular, and were 

 without the prominent processes which occurred on some of the 

 earlier specimens found on the refuse heap. Evidently, therefore, 

 this was the tail end of the animal, and unfortunately the most
