40S Account of some remarkable Caves , &c. 
Besides the smaller hollows, spoken of before, round this 
fourth cave, a very narrow opening has bee 1 discovered in one 
of its corners. It is of very difficult access, as it can be en- 
tered only in a crawling posture This dismal and dangerous 
passage leads into a fifth cave, of near 30 feet high, 43 long, 
and of unequal breadth. To the depth of six feet this cave has 
been dug, and nothing has been found but fragments of bones, 
and animal mould: the sides are finely decorated with stalac- 
tites of different forms and colours ; but even this stalactical 
crust is filled with fragments of bones sticking in it, up to the 
very roof. 
From this remarkable cave, another very low and narrow 
avenue leads into the last discovered, or the 
Sixth cave, not very large, and merely covered with a sta- 
lactical crust, in which, however, here and there bones are seen 
sticking. And here ends this connected series of most remark- 
able osteolithical caverns, as far as they have been hitherto ex- 
plored; many more may for what we know exist, hidden, in 
the same tract of hills. 
Mr. Esper has written a history in German of these caves; 
and given descriptions and plates of a great number of the 
fossil bones which have been found there. To this work we 
must refer for a more particular account of them.
