NOTES AND QUEEIES. 
Correlation of the Grey Chalk and Upper Greexsand. — There is 
no more important point to be settled in the physical geolo^^y of the Cre- 
taceous formation than the determination of correspondinj^ horizons over 
different geographical areas of the Grey Chalk and Upper Greensand. The 
stratigraphical range of fossils in each, and the collating of those of both 
deposits from different localities with each other, would work out some 
important results. It is too much, perhaps, to ask our readers who live in 
chalk or greensand districts to send in lists of all the fossils they have col- 
lected, — althougii we should be very thankful indeed for such lists ; but by 
drawing attention to two of the characteristic fossils of the Grey Chalk 
which we have figured in Plate X., we shall possibly receive through the 
kindess of our many friends, notices of the localities and strata in which 
they know them to occur. To note the beds and the places in which col- 
lectors have found these two shells will cost them a mere fraction of trou- 
ble, while the result will be an indication of considerable value in deter- 
mining the conditions of deposits, and the possible synchrony of those two 
great deposits, and will help to bring isolated Cretaceous deposits into 
place in the chronological series. — S. J. Mackie. 
Subterranean Trees at Puefleet. — Here (Purfleet) was a ferry over 
the Thames into Kent. That river made a breach and inundation at West 
Thurrock in the year 1680 ; at which time subterranean trees were washed 
out in as great numbers, and of the same kind of wood, as those found in 
Dagenham and Havering levels in 1707. (See Phil. Tr. No. 335, p. 478; 
and Abridg. by H. Jones, vol. iv. part ii. p. 219 ; and Morant's Essex, 
Tol. i.)

natural section seen at Hilton Beck, north of Brough, estimates to be of 3000 feet ia
