we would urgenily solicit all those intelligent persons who 
have access to our caverns, especially in the great limestone 
formations, to cause the loose earthy materials on the floor of 
those caves, to be explored for bones, and if any are found 
to have them carefully preserved and examined, and the facts 
reported. Wherever extensive excavations have been already 
made, for the purpose of obtaining nitrous earths, it is re- 
spectfully suggested that the workmen should be interrogated, 
and their refuse materials inspected with care. We look to 
our scientific friends in the western and south-western states 
and colleges, for the influence and efforts necessary to this re- 
search, Professor Buckland regards Dr. Hayden’s Geolo- 
gical Essays, as a work of much value in relation to his re- 
searches into the facts connected with the American diluvial 
tending to “* confirm our expectation of the universality of the 
general order of superposition.” 
Mr. Buckland mentions that a letter from Professor Savi 
of Pisa, had just given him information of the existence, in 
the limestone of the neighbourhood of Carrara and the gulph 
of Spezzia, of caves containing bones of peers, bysenass &c. ; 
he was about proceeding without delay to investigate the 
facts.

im collections, more or less extensively labelled, described, 
and classified, may be obtained of Freper1c MoupEN-

from him a letter, which states, that he will furnish collections, 
either for money or in exchange for American minerals: the 
prices and i may be learned by she eyes ofa 
printed catalogue, which has been transmitted by M. Mol-
