figs. 1 a-lc) ; also a triangular flint of Palaeolithic outline (PL XIY, 

 tigs. 2 a-2 c), but having ' Eolithic ' ' edge-chipping ' about the 

 apex, the colour and patination resembling those of the ' Eolithic * 

 forms found in the pit generally. Among some of the disturbed 

 gravel in the pit Dr. Smith Woodward found a flint worked on 

 one face and simply flaked on the other face, and similar to the 

 Palaeolithic flints described in our last paper. 



An incisor of a Beaver {Castor fiber) and portion of a mandible 

 occurred in the dark gravel : the former close to the spot where 

 the molars were found last year, and the latter some 12 yards 

 awav to the south. One of the molars agrees in size with a socket 

 of the alveolar border. 



The whole of the work was perforce carried on very slowly, and 

 we found it impossible to employ more than one labourer, for the 

 actual excavation had to be closely watched, and each spadeful 

 carefully examined. The gravel was then either washed with a 

 sieve, or strewn on specially-prepared ground for the rain to wash it ; 

 after which the layer thus spread was mapped out in squares, and 

 minutely examined section by section. 

 / While our labourer was digging the disturbed gravel within 2 or 

 3 feet from the spot where the mandible was found, I saw two 

 human nasal bones lying together with the remains of a turbinated 

 bone beneath them in situ. The turbinal, however, was in such 

 bad condition that it fell apart on being touched, and had to be 

 recovered in fragments by the sieve ; but it has been pieced together 

 satisfactorily by Mrs. Smith Woodward. 



All the gravel in situ- excavated within a radius of 5 yards of the 

 spot where the mandible was found, was set apart and searched 

 with especial care, and was finally washed and strewn as before 

 mentioned. It was in this spread that Father Teilhard de Chardin, 

 who worked with us three days last summer, on August 80th, 1913, 

 discovered the canine tooth of Eoanthropus, hereafter described. 

 In this way also Dr. Smith Woodward recovered a small fragment 

 of a tooth of Rhinoceros, in the same state of mineralization 

 as the fragments of teeth of Stegodon and Mastodon. 



There now remains little excavation to be done in the immediate 

 vicinity of the site of these remains. Other excavations which we 

 have made in the pit have so far proved unproductive of fossils ; 

 but we have opened up some trial-holes which give evidence of a 

 continuation of the bedded gravel to the west, under the plough- 

 land there, and across the small valley on the east near Moon's 

 Farm House. 



Conclusions. 



We cannot resist the conclusion that the third or ' dark bed ' is, 



1 in the main, composed of Pliocene drift, probably reconstructed 



in the Pleistocene Epoch. The evidence seems to point towards 



a marking-off of the third or ' dark bed ' from the second or 



lighter bed, that contained a triangular Palaeolithic implement,
