TRACES OE MAN FOUND IN THE ROBIN-HOOD CAVE,

which has been observed in neolithic arrow-heads, intended to make 

 the arrow revolve in its flight. It measures 3*8 by 1-42 inches. A 

 fragment of a second specimen was also found corresponding with 

 the upper part of fig. 7, and as nearly as possible of the same size and 

 form as a specimen in the Oxford Museum from Wookey Hole. In all 

 these implements the salient midrib of the flake has been left intact. 



If this latter form (fig. 7) be compared with those figured in the 

 ' Reliquiae Aquitanicae ' from Perigord, it will be seen that it bears 

 a strong family resemblance to some of those from Laugerie Haute 

 (a, pi. iv. figs. 7, 8, 9). They are also of the same type as those 

 from the Pleistocene portion of the deposits at Solutre figured by 

 MM. Ducrost and Lortet (Archives du Museum d'Histoire Naturelle 

 de Lyon, ii. pi. v.), and considered by M. de Mortillet to be cha- 

 racteristic of a stage in the Palaeolithic culture. 



Two other fragments of trimmed flakes were found, both with the 

 salient ribs worked carefully off and the flat inferior surface intact. 



In fig. 8 an implement is represented formed of a flake with 

 the cutting-edge carefully and minutely chipped. The inferior sur- 

 face is, for the most part, flat and un worked, while the superior is 

 occupied by the natural surface of the flint-pebble. It is probably 

 a scraper, analogous to that from Kent's Hole, fig. 392 of ' Ancient 

 Stone Implements.' 



Eleven flakes, with one of their extremities trimmed to a rounded 

 edge, were met with. They are of the usual type so common in the 

 caves of Perigord. One fragment is of the same form as the upper 

 half of fig. 396 of 'Ancient Stone Implements,' and is composed of a 

 flake struck from the outer side of a flint-pebble.

Figs. 9 and 10 represent two very singularly worn flakes like those 

 which have been figured by Mr. Evans (figs. 398, 399, 400) from Kent's 

 Hole. The first consists of a flake with " an oblique straight scra- 

 ping edge, forming an obtuse angle with one side of the flake, and an
