not more than '2 inch thick. The tool was found alone on February 11, 

 1880, in the Breccia, in the eighth foot-level below the Granular Stalag- 

 mitic Floor. This specimen is peculiarly interesting, on account of a 

 remarkably well-developed ' bulb of percussion ' in one of the lateral 

 edges, about two inches from the butt end. It was found alone, in the 

 Breccia, in the eighth foot-level below the Gi*anular Stalagiaiitic Floor, on 

 June 2, 1880. 



No. 7329. A flint chip, not quite an inch long, found alone, in the 

 Breccia, in the ninth foot-lovel, on February 13, 1880. 



No. 7330. Piece of bone, found alone, in the Breccia, in the seventh 

 foot-level, on February 27, 1880. 



No. 7331. A small polished agate, set in silver, found alone, on the 

 surface, on March h. This trinket of the present day must have been 

 accidentally dropped by one of the numerous visitors to the Cavern since 

 the four-feet excavation in that part of the Cavern was finished ; that is, 

 since February 1873. 



No. 7332. A flint flake or chip, o'l inches long, l"o inch in greatest ' - /! 

 breadth, and nearly -5 inch in greatest thickness. It retains a small (\' i- 

 portion of the original surface of the nodule from which it was dis- 

 lodged, but has no indication of having been used or intended for use. 

 It was found alone, in the Breccia, in the fifth foot-level, on March 6, 

 1880. 



No. 7333. A. flint flake or chip, 2'5 inches long, 2*2 inches in greatest ' ^ ^ ^r 

 breadth, and '6 inch in greatest thickness. It retains a considerable por- 

 tion of the original surface of the nodule from which it was struck, and 

 was found alone, in the Breccia, in the eighth foot-level, on March 17, 

 1880. There is nothing about it to suggest that it was ever intended for 

 use. 



No. 7334. A left last upper molar of Bear, with a piece of bone, 

 found alone, in the Breccia, in the seventh foot-level, on April 1, 1880. 



No. 7335. A flint nodule, 3'6 inches long, 2^8 inches in greatest 

 breadth, and 2 inches in greatest thickness. It is pretty much rounded, 

 no attempt has been made to fashion it into a tool, and indications of its 

 having been used as a ' hammer stone ' are neither numerous nor well- 

 pronounced. It was found alone, in the Breccia, in the sixth foot-level 

 below the Granular Stalagmitic Floor, on April 13, 1880. 



No. 7336. A small chert chip, found alone, in the Breccia, in the sixth 

 foot-level below the Granular Stalagmitic Floor, on April 24, 1880. 



No. 7337. A fragment of an unusually smoothly- worn pebble, or of 

 the internal cast of an Orthoceras, found alone, in the Breccia, in the ninth 

 foot-level below the Granular Stalagmitic Floor, on May 21, 1880. 



No. 7338. A small flint chip, found alone, on May 31, 1880, in the 

 Breccia, in the fifth foot-level below the Granular Stalagmitic Floor. 



No. 2339_. A flint nodule-tool, 5'75 inches long, 3 inches in greatest 

 breadth, and 2'7 inches in greatest thickness. In form it approaches a 

 four-sided pyramid ; at the butt end each face is covered with the original 

 crust of the nodule, and the apex is not well formed. 



No. 734(X A mass of flint owing its present irregular form to arti- '^ 

 ficial chipping, but not entitled to the name of tool. It is 335 inches 

 long, 2'9 inches in greatest breadth, 1'8 inches in greatest thickness, and 

 retains a small patch of the original surface of the nodule, where there 

 are a few bi'uises such as might have been produced by its having been 

 used as a ' hammer-stone.' It was found alone, in the Breccia, in the
