the deposit to another or re-arranged its constituents. Occasionally, 

 under large stones or in peculiarly situated spaces, the material was 

 more friable and loose, or even a space left ; but, so far as I could 

 see from careful observations during nearly three years (in which 

 time I handled, sifted, or washed scores of tons of material), I could 

 see no possibilities of communication from one part of the fissure to 

 another to any great extent. At the last inset, and as I worked the 

 fissure farther back, the deposit was far less solid, more carbonaceous, 

 and showed more cavities, and I quite expect this phase to increase 

 as one works inwards. 



It is the vertebrates, of course, that arc the most important 

 fossils of the fissure; but having stated the conditions under which 

 they were found, I leave their description to far more competent 

 hands than mine. I might, perhaps, remark that many of the bones 

 are peat-stained, as though they had lain upon a peaty river-bank 

 before entering the fissure, which colouring they never lost ; they 

 occurred irregularlv all through the fissure in juxtaposition to the 

 unstained bones. The same remarks apply to the gnawed bones. 

 In a few instances, in the case of a bat, a vole, a mole, and a 

 slow- worm, the creature entered the fissure very nearly or quite 

 whole, and their bones occurred near each other ; but it was usually 

 otherwise, the bones being single and isolated.
