150 HAZZLEDINE WARREN : STUDY OF PRE-HISTORY IN ESSEX. 
sub-glacial conditions after the Moustenan epoch, or Middle 
Palaeolithic, as the relics belonging to this stage are found in 
the Mid-Terrace. 
IV. Palaeolithic Deposits : Stratigraphy and Fauna 
(for the most part excluding Human Implements). 
Papers dealing with Palaeolithic Implements are tabulated 
under the next section (V.). The few minor references to 
Implements included in this place are also recorded (as cross 
references) under the next section. , , But practically all the 
papers under the next heading at least imply evidence on strati¬ 
graphy or fauna ; so that, for these subjects, the two headings, 
IV. and V., must be taken together ; but, for human implements 
•only, the records under the next heading are complete.

High Terrace and general conclusions on the physical history 
of the Lower Thames and of the Mardyke. These im¬
