stone of this bed having been removed, as they were taking 
way a stratum of argillaceous sand, which separated the 
eleventh bed from the twelfth, they found stumps of columns 
and fragments of stones half wrought, and the stone was 
exactly similar to that of the quarry : they found moreover 
coins, handles of hammers, and other tools or fragments of 
tools in wood. But that which principally commanded 
their attention, was a board about one inch thick and seven 
or eight feet long ; it was broken into many pieces, of which 
none were missing, and it was possible to join them again 
one to another, and to restore to the board or plate its ori- 
ginal form, which was that of the boards of the same kind 
used by the masons and quarry men: it was worn in the 
same manner, rounded and waving upon the edges 
“ The stones which were completely or partly wrought, 
had not at all changed in their nature, but the fragments of 
the board, and the instruments, and pieces of instruments of 
wood, had been changed into agate, which was very fine 
and agreeably coloured. Here then, (observes Count Bour- 
non,) we have the traces of a work executed by the hand of 
man, placed at the depth of fifty feet, and covered with 
eleven beds of compact limestone : every thing tended to 
e that this work had been executed upon the spot 
where the traces existed. The presence of man had ther ~ 
preceded the formation of this stone, and that very consid- 
erably since he was already arrived at sucha degree of 
civilization that the arts were known to him, and that he 
wrought the stone and formed columns out of it.” 
3. Fossil Bones found in red sand stone, communicated by 
Professor NarHan Smita. 
Mr. Solomon Ellsworth, Jun. of East-Windsor, (Conn.) 
has politely favoured me with some specimens of fossil 
nes, included in red sand stone. Mr. Ellsworth informs 
which contained it, and several pieces of bones had_ beer 
picked up, and then lost. The specimens which I have
