the Honorary Secretary, had excavated a portion of the sandy 
matrix, and collected from it a considerable number of bones and 
teeth. 
A meeting- of the Council of the Society was held on the 
10th December, 1879, to consider the propriety of attempting- a 
scientific investigation of the Cave, and it was resolved : — 
' ' That it is desirable that steps should be taken to secure a thorough 
investigation of the Eaygill Fissure and its contents, and that Profs. Green 
and MialL and Messrs. Brigg and Davis, with power to add to their number, 
be appointed a Committee to carry out the exploration." 
It was also decided that a special fund should be obtained, en- 
tirely separate from the income of the Society, and that so soon 
as this fund should amount to .£50 operations should be commenced. 
A circular was issued a few days later to the members of the 
Society and others interested in Cave explorations, with the result 
that up to the present time nearly £60 have been subscribed. 
Operations were begun on Monday, June 7th. Mr. Spencer placed 
at our disposal workmen skilled in the class of work required, and 
instructed his manager, Mr. Todd, to assist us in every way he 
was able. The fissure as already observed opened into the face 
of the Quarry towards the north. The limestone at this part dips 
at a sharp angle into the hill towards the south. The top of the 
opening was about 50 or 60 feet beneath the surface of the ground 
above. The lower part of the opening was about the same 
distance above the floor of the Quarry. The entrance to the fis- 
sure was 27 feet 6 inches in vertical height and 9 feet across. 
The section in the exposed face of the Cave (June, 1880) shewed 
the following beds : —

1 . Finely laminated clay
