Since the occupation of the shell by the earthy materials, 
after the death of the animal, the shell has crumbied down 
and disappeared, while its packing or filling remains. 
9. Teeth of the horse, in sound condition. 
10. Moulds in marl of turbos, buccinums, and other 
univalve shells. 
It ought to be remarked that this region, reported to be 
from two to five miles wide, is one of the most memorable 
on the globe. If, in addition to the preceding enumeration, 
it is added, that singular baculites (here)—vertebre of 
sharks, and their teeth (here)—pipes of clay, which men 
have used for smoking (here also)—metallic buckles and 
tongs, and numerous other natural and factitious things, 
have been found by the proprietors or agronomes, while 
exploring the strata of their farms for manure,—it would 
seem that a belt or zone of earth so memorable as this, 
is worthy of further exploration. The Reynolds’s, the 
Vanderveers, the Crawfords, the Teneycks, the Scotts, and 
the Bennetts, among others, deserve worthy notice on this 
occasion. 
11. Lignite, or black mineralized wood ; from a depth 
of fifty feet below the surface: right bank of the Raritan, 
New-Jersey, Essex county. 
12. Sharks’ teeth, some black, some white: Cranbury, 
near Princeton.—Professor Green: with a singular semi- 
globular substance containing shells. 
13. Amber, with shells adhering, and an accompanying 
belemnite.—Crosswick’s Marl Pit, New-Jersey. 
14. A collection of detached shells, such as various 
kinds of clams, oysters, gryphzeas, volutes, turbos, bucci- 
nums, &c., from the neighbourhood of Fort Claiborne, 
along the river Alabama, where they form thick and exten- 
sive layers, not yet hardened into rock. 
15. A piece of petrified wood, from the same region. 
16. A large and interesting block of live oak, appa- 
rently changed to silicious stone.
