RAYGILL FISSURE. 
The following section will serve to explain the relative 
position of the beds hitherto worked. It is a section across the 
fissure in a north and south direction. 
1. Laminated clay. 
2. Sand, and sandy clay with boulders, without stratification. 
3. Brown sandy clay, with rounded stones blackened, and numerous 
bones of animals. No stratification. (Bone-earth.) 
4. Stiff yellow clay, with large masses of angular limestone. 
The bones in No. 3 have always been most numerous towards the 
front of the opening-. No. 4 is the stiff yellow clay, it is about 
9 feet thick, and is full of large masses of fallen limestone — 
angular but waterworn. Mr. Todd says that this yellow clay is 
very similar to the yellow clay which was found in the upper part 
of the Cave before the level at which our operations began was 
reached. The yellow clay extends from near the face of the 
Quarry backwards for a distance of 18 feet, and behind it the 
brown bone earth fills up the Cave. The bone-earth in the lowest 
part worked has yielded several fine specimens. There does not 
appear to be any difference either in the character of the material 
or the animal remains found in it, from that higher in the fissure. 
A nearly perfect tusk of the Hippopotamus measuring 12 inches 
in length was found in this part. The bones of Hyena. Hippo- 
potamus, Elephant, and Rhinoceros are also tolerably abundant, 
and in all respects the character of the fauna appears to maintain 
a similarity thoughout. 
Near the bottom of the vertical part of the Cave there has 
been found the broken antler of a Roebuck very similar, but 
more perfect, to the one found higher in the Cave; and the 
molar tooth of a Bear. Perhaps the most important discovery has 
been the molars of a Lion, Felis leo, var. spelcea. 
Note, — Since the foregoing was written, a large quantity of 
the yellow clay and bone earth have been removed from the lower 
part of the vertical portion of the fissure, and for a short distance 
into the nearly horizontal branch, proceeding in an easterly direct- 
ion. The opening in that direction is large, and contains a quantity 
of material, reaching almost to the roof of the fissure. AVhere the
