grey chalk. ‘These are associated with numerous particles of 
transparent white and green quartz; Fig. 3. 
all vestiges of the shells having been 
destroyed by the acid. Fig. 3, is the 
body of a Rotalia deprived of its shell 
by the process previously described ; it 
consists of fourteen sacs, in their natu- 
ral position, whichare filled witha dark ¢ 
eral dark globular bodies (a), that re- 
Semble in shape the ova of certain Gasteropoda. That these 
belong to the same animal seems probable from the occurrence 
of similar ova in another fossil, which is the body of a 0- 
talia seen foreshortened in the horizontal plane; in this speci- 
men four large sacs are exposed, and these exhibit in a striking 
manner the folded condition of the integument of which they 
are nena The globular bodies (ova?) are twenty-one in 
papille, which may be regarded as indications of the bases of 
udopodia. On this fossil I cannot forbear to observe, that 
_ On examining by reflected light, under the microscope, some 
Pieces of chalk collected from the stratum which yielded the 
fossils above described, minute particles of a brown color may be 
observed scattered over the surface; these I have no doubt are 
remains of the integuments of foraminifera; for in one instance,
