ON THE RELATION OF PALHZOLITHIC MAN TO THE GLACIAL EPOCH, 405 
DESCRIPTION OF THE Deposits AND THEIR Iossizs.! 
Bed A. 
This is the only deposit usually exposed in the brickyard, and from it 
the Paleolithic implements (see fig. 3) are obtained. Hoxne Brickyard 
for many years seems to have been worked mainly for this upper brick- 
earth, from which are made the red bricks. It thus happens that over an 
extensive area nearly the whole of Bed A has been removed, and the 
sides of the pit are so overgrown that it is difficult to obtain detailed 
measurements. There are clear sections, however, on the opposite side of 
the road in the new pit in Oakley Park where this brickearth is now worked ; 
the material from which were obtained the fossils given in the list was 
therefore taken from that pit. The sections in the old yard, as far as they 
can now be examined, are similar, and fossils and flint implements occur 
there in the same manner.

During the last two years three implements have been obtained from 
this spot, usually at a depth of from 5 to 7 feet from the surface. Bones 
are rare, but we obtained from the men some belonging to horse and deer, 
and apparently to elephant. Samples of the laminated shelly loams taken 
in 1896 yielded the species of mollusca and plants mentioned below. The 
bones were obtained from the workmen in 1888 and 1895.

Limnza glutinosa, Will. Chara. 
The list contains no species characteristically either northern or 
southern, and even the assemblage throws little light on the climatic 
conditions. Limnea glutinosa, not previously recorded as a British fossil, 
does not extend far north ; but the rest of the mollusca range from the 
Arctic regions to the south of Europe, and all of them are to be found. 
‘ For convenience of reference the fluviatile and lacustrine strata have been 
lettered A to E (see Plate and fig. 1).
