that it is much more difficult to say where they are not, 
than where they are to be found. The Crag' at Bawdsey 
Cliff, near the mouth of the Deben or Helen River, is partis 
cularly deserving attention, not only for the variety of 
shells which it produces, but because you may discover 
in various parts of it, particularly the southern extremity, 
the base on which it rests, and which appears to be blue 
Clay, and such is the Anchorage ground in Hollesley 
Bay, N. E. of it, visible at ebb tide. On elevated ground, 
to the west of Melton, N. N. E. of Woodbridge, is a Crag 
pit, just on the confines of the deep soil of High Suffolk, 
its produce mixes with the fossils of the blue Clay. At 
Shottisham, S. E. of Woodbridge, I found the Mu rex. 
despectus ; near Brightwell and Foxall, S. W. of Wood- 
bridge, the reverse Murices and Chamee abound ; near 
Woodbridge is a vein of imperfect specimens of Venus 
Islandica,but I never could extract an entire specimen. At 
Sudbourn, N. of Orford, the Crag is of a much paler 
colour, and of so concrete a texture, that some wails at 
Orford are built with it ; and in sinking wells through 
it at Sudbourn no other support is wanted for the sides. 
The Crag near Aldborough is very loose.* I believe that 
the soil of the country between the rivers Orwell and 
Stour, S. and S. W. of Ipswich, is similar to that of the 
Sands, and equally abundant in Crag ; but I have 
never examined any part of it except the neighbourhood 
of Wherstead and Belstead. To the westward of Ipswich, 
Crag was formerly seen on high ground, which is now 
concealed by plantations ; and about half way down, be- 
* It consists of fragments mixed with entire shells of Pectens and some 
others, corals, &c. adhering - together around the spaces formerly occu= 
pied by other shells, such as Voluta Lamberti, Venus, islandiea, &c. 
that have left behind them here nothing but their impressions, while iu 
other places they are found entire.
