In a recent visit to the Cretaceous formation of New Jersey, he has 

 brought to light the interesting fact that a large portion of the cal- 

 careous rock, defined by Prof. H. D. Rogers as the third formation of 

 the upper secondary, is made up, at the localities where he examined it, 

 of great quantities of microscopic shells, belonging to the Foraminifera 

 of d'Orbigny, which order includes those multilocular shells, which com- 

 pose a large part of the calcareous sands, etc. , of Grignon and other 

 localties, in the tertiary deposits of Europe. Since the minute multilocu- 

 lar shells above alluded to were discovered. Dr. Torrey and Prof. Bailey 

 have together examined specimens of limestone from Claiborne. Alabama, 

 and have found in them Foraminifera, of forms apparently identical with 

 those occurring in New Jersey. None of this order, except the genus 

 Muininulite, have heretofore been noticed in our green-sand formation.

p. cimeata. PI. xi. fig. 5. Shell ovate, slightly angulated in the mid- 

 dle ; one side slightly concave, with concentric lines, which are angular 

 in the centre of the disk. Length three-tenths of an inch.

f n an excursion which I made in New Jersey, in September, 1841, in 

 company with Mr. Conrad, we went first to Bristol, on the Delaware, 

 next, by Bordentown, to New Egypt, and returned by Timber Creek, re- 

 crossing the Delaware at Camden. 



In the upper or straw-colored limestones, I found on the banks of the 

 Timber Creek, twelve miles southeast of Philadelphia, six species of 

 corals. The same calcareous formation also abounds in Foraminifera, 

 characteristic of the chalk, comprising, among others, the genera 

 Cristellnria, Rotalina and Nodosaria. 



I saw the formation in question, on the banks of Timber Creek, a stream 

 which flows into the Delaware three miles below Philadelphia. 



The principal locality is twelve miles southeast of Philadelphia, about 

 a mile and a half south of the village of White Horse, Gloucester County, 

 New Jersey.
