186 Intelligence and Miscellanies. — Domestic. 
the two great Continents of the old and the new world, (as 
they are called.) Ihave determined at once to direct to 
you the transeript in question from Professor Buckland’s 
Letter to me which is as follows.

** | lately received a very valuable box of specimens col- 
lected by Major Delafield from the Lakes of North Ameri- 
ca ; chiefly lime stone, full of organic remains ; and both 
stone and shells so precisely similar to those of the transition 
limestone of Dudley and Longhope, that it is quite impossi- 
ble to distinguish them. Oethoceratite, Chain cord En- 
crinites, T'erebratulites, (No. 42. pl. 13. vol. 2, of Parkin- 
son’s Organic Remains,) and millions of minute and almost 
microscopic millepores crowd all these specimens, and 
prove decidedly the masses whence they are taken to be 
the transition lime stone of England. 
‘Similar specimens were sent to London by Lieut. 
Franklin from Cumberland House, where he quartered last 
winter, in his way to the Copper mine River ; and by Cap- 
tain Perry from his new Islands, within Barrow’s Straits. 
‘*‘ The same limestone, containing the same shells, occurs 
largely in Sweden, and the Islands of Oland, Gothland, and 
Bankolm, and in the country round Petersburgh ; there 
and in England, the rock is characterized by containing al- 
so the Dudley fossil, and trilobite, of which no specimen is 
sent in the small set (only 15) which I received from the 
American Lakes. 
** No doubt, however, it will be found there. Thus the 
transition limestone assumes an immense importance in thus 
extending (with precisely the same features) from the old 
to the new world, under nearly the same parallels of lati- 
tude, and containing at such great distances the same or- 
ganic remains! The specimens sent, were chiefly from 
Drummond’s Islands, and Thessolar Island, on Lake Hu- 
ron.” 
Mr. Buckland adds in his letter, from which the foregoing 
is an accurate copy, ‘‘ Perhaps the above circumstances of 
the interesting and important analogy in the formation of 
Northern Europe and America may be worth communica- 
ting to Professor Silliman, for his Journal, which I hope may 
be continued as ably as itis begun.”
