a Theory of the Earth, 
10. Whether, on the other hand, their identity is con- 
firmed with those of analogous living ones ; viz. to as- 
certain whether these analogous living ones are found at 
present, or have been found within the memory of man, 
in those countries which contain remains of them ; and if 
the answer is negative, to discover the situation and dis- 
tance of the nearest country where they are found. 
11. If no analogous ones exist alive at present but in 
climates where the temperature is very different, to ascer- 
tain whether there are any indications of their having 
formerly existed, and of their having been conveyed to 
those countries where remains of them are still found ; or 
whether, on the contrary, these remains seem to have 
been transported thither by currents, tides, or any other 
great movement of the waters. 
12. In the like manner, whether there are found in the 
cold countries vestiges of the productions of warm coun- 
tries ; or reciprocally, whether in warm countries there 
are found vestiges of the productions of cold countries. 
18. Whether fossil wood, or other vestiges of organi- 
sedbodies, are situated in such a manner as to indicate that 
there were in the ancient ocean islands abounding with 
animals and vegetables. 
14. To study with care the immense accumulations of 
bones deposited in heaps ( nids ), or strata, in the isles of 
Cherso, Osero, and elsewhere. 
15. To examine the nature of the caverns which con- 
tain them ; such as Baumannshcele , and others 
16. Whether it appears that these caverns Were the 
voluntary retreats of those animals who died there a na- 
tural death, or whether their bodies were conveyed thi- 
ther by the waters f. 
* In the Harz, and those of Gailenreuth in Franconia. Til. 
t 0r > whether these bones are found, not only in caverns, but also in the strata 
from which the caverns have been formed.. Til.
