has been found at Ipswich. Also in Suffolk, flints stated 

 to be humanly worked, with barnacles of the Red Crag Sea 

 attached to them, have been excavated from the base-beds of 

 the Crag. Excavations and other investigations in France have 

 tended to prove that different types of Palaeolithic implements 

 occur in succession in the same order at different places, and 

 show their gradual development from an early form to the latest. 

 Recently, excavations in Kent have shown a similar succession 

 of types from the Strepy in the lowest stratum through 

 Chellean, Chelleaii evolue, St. Acheul, Solutre, and Le 

 Moustier, forming a similar sequence to that of the Somme 

 Valley. The subject of worked flints is a difficult one, as 

 many of the forms are doubtless produced by natural causes 

 and are probably even harder to distinguish from the ancient 

 artificial ones than some modern imitations of antique china 

 and glass are to tell from the really old specimens. Under 

 these circumstances little reliance can be placed on them as 

 evidence unless the traces of human manufacture are clear 

 and indisputable. Much further discussion has taken place as 

 to the shape of skull which the Piltdown fragments represent 

 and as to its age, about which opinions differ widely. It also 

 seems doubtful if the Galley Hill and Ipswich skeletons are 

 nearly so old as they have been represented, the evidence being 

 unconvincing. It is improbable that any really early 

 human remains have yet been found in S. America, and I 

 believe that none have been discovered in S. Africa, though 

 quantities of Palaeolithic implements have occurred in the 

 latter country. A discovery of what may be an ancient 

 skeleton has lately, however, been made in German E.Africa, 

 the man being stated to have had 36 teeth, some of which 

 were filed, a curious habit for a very early race, and one 

 which throws a little doubt on its supposed age. What is 

 believed to be the earliest known drawing of a human figure 

 has been found engraved on a mammoth bone in the upper 

 Aurignacian layer near Poucin, in France, and numerous 

 paintings in red have been found on rocks in caves in Spain, 

 some shewing men hunting the stag. An apparently
