URING the making of the Midland Company’s Isine from 
Mouldsworth to Chester, interesting Sections of the Drift 
deposits were exposed, especially in the Newton cutting, about 
a mile and a half from the Victoria Station, Chester. In the 
Upper Boulder Clay of the Newton Section I have found 56 
species and varieties of Mollusca; 2 Pelyzoa, 26 Ostracoda, 
2 Cirripedia, 2 Annelida, 3 Echini, 2 Spongida, and 55 Fora- 
minifera, or in all 148 species and varieties of marine animals’ 
remains. From a sand-pit, owned by Sir P. De M. Grey- 
Ecrerton, Bart., M.P., F.R.S., at the village of Upton, about 
two miles from Chester, Mr. G. W. Sxrussore and myself 
have gathered 23 species of Mollusca. 
In the Lower Boulder Clay of the cliffs of Dawpool, Wirral, 
Cheshire, Mr. D. Macxrintosu, F.G.S., and myself have found 
85 species of Mollusca, in addition to which I have also 
obtained from this locality 1 Polyzoa, 15 Ostracoda, 1 Cirriped, 
) Annelid, 2 Echini, 2 Spongida, and 32 Foraminifera. 
The whole of the Microzoa were obtained from the sand which 
fills the internal chambers of the Univalve Mollusca in the 
Upper and Lower Boulder Clays. A most interesting fact, 
bearing upon this subject, was observed by my mother, Mrs. 
SHone, who, upon examining some silt gathered from Gorteen- 
beach, Connemara, by Mr. R. D. Darsisuire, B.A., F.G.S.,
