442 Scientific Intelligence. - 
Agelocrinites in our strata, contributed a new member to the family ; 
and now by the discovery of these interesting specimens, we are en- 
abled to add two other genera, species of which have rarely been found 
in deposits anterior to the chalk. 
The locality where these remains were found, is about one mile north 
of the city, near the Vine-street road, and about 300 feet above low 
water mark of the Ohio river. Near this spot have been found hun- 
dreds of very perfect Encrinites, having in many cases the column at- 
tached to the head; and also in the same vicinity occur fine specimens 
of a cabideditig this — a favorite one to the collector 
of fossil remains.

6. ~shereatend fluid in the Planorbis imbricatus, (L’Institut, No. 627, 
Jan. 1846, p. 4.)—M. Quatrefages has observed that in the Planorbis im- 
bricatus, common in the fresh waters of the vicinity of Paris, the blood 
has the red color of the lees of wine. When but little magnified, the cir- 
culating fluid may be seen filling the cavities of the pericardium and ven- 
tricle, and at short intervals to color quite distinctly the general cavity 
of the body throughout its inferior surface. 
7. Siliceous shields of Infusoria from Guano.—The guano from Icha- 
boe, when long digested in acids, leaves a siliceous residue, which, ex- 
amined under the microscope, with a- power magnifying from 200 to 
400 linear, is found to consist entirely of the shields of Coscinodisca, 
Actinocyclas, &c. &c., of the most exquisite forms, and presenting the 
most beautiful play of colors.
