large coups-de-poing occur, only little tiny varieties, one of which 

 was actually found in situ in the upper beds. These small coups- 

 de-poing may be compared with a small example which, from its 

 patina, has been placed in the first series. This latter is, however, 

 very much more waterworn, and the trimming is different. A few 

 borers have been found, as well as side scrapers, and some small 

 flat oval flakes. It should also be noted that facetted striking- 

 platforms occur, and attempts, often not very successful, have been 

 made to remove the bulb of percussion. 



It seems safe to conclude that in the case of Series a we are 

 dealing with a typical Lower Palaeolithic industry, composed pro- 

 bably of an admixture of Chellean and Acheulean forms. The 

 admixture has certainly been made by water, producing the water- 

 worn appearance that has been already noted. 



Series b does not seem far removed in time from Series a, as is 

 shown by a comparison of the small coups-de-poing from the two 

 series. It may be of late Acheulean, or more probably of Lower 

 Mousterian age. This would bear out the little stratigraphical 

 work that has, so far, been possible. Series a can be certainly 

 compared with the industry at ' Three Hills.' Series b may be 

 of the same age as the implements of ' High Lodge.' 



With regard to the finds of later date from the Milton Pit. etc., 

 I can only say that there is nothing to add to Prof. Marr's state- 

 ment of the case. The finds are few, and it is to be hoped that 

 further evidence will be forthcoming. However, the general 

 appearance of the implements suggests an Upper Palaeolithic age. 

 It is unfortunate that the layer from which the Avell- worked core- 

 scraper came cannot be demonstrated for certain. The difference 

 between the derived waterworn implements of earlier age and 

 those of the same age as the deposit is very marked.

Discussion. 



Sir William Boyd Dawkins welcomed the paper as the first 

 instalment of a series on the Pleistocene strata of the district of 

 Cambridge. He was glad that the Author, in dealing with the 

 stone implements of the various deposits, divided them up into 

 the three Early Palaeolithic 'types' of Chelles. St. Acheul, and 

 Le Moustier, without falling into the common mistake of treating 

 them as characteristic fossils for the purpose of classifying the 

 strata into those three periods. In the speaker's opinion, from 

 the geological point of view, all three are of the same approximate 

 age, and their division by the archaeologists into three successive 

 periods in France will not apply to England. Here all three types
