larger, being about 1 ^ inches in length. In order to show how such 

 crescent shaped flints may have been used as arrows he figures one tied 

 with its dressed and convex side to a shaft, so that one of the points 

 forms the point of the arrow and the other projects from the side as a 

 barb. I show in fig. 47, No. YIII., a small implement from Helouan 

 similar in kind and size to those figured by M. de Morgan which, while 

 it would make a very good knife, would, owing to the rather thick butt 

 and also curved point, make an indi:fferent arrowpoint and barb. I also 

 show in fig. 52 a figure of a flake of nearly the same shape, but without 

 dressing, from Morahna Pahar, India. M. Grabriel de Mortillet figures 

 a number of small implements in Formation de la Nation Fra7igaise, 

 p. 250. They were found in the neighbourhood of Fere-en- Tardenois 

 (Aisne), and are' of Neolithic age. He figures nine examples, of which 

 foiu' correspond very closely to figs. 35, 42, and 44 in No. YIII. The 

 remainder are in the form of triangles, except that two of them have 

 concave bases. He figures on page 251 a small implement similar to 

 fig. 44 on No. YIII., only qiiite perfect at both ends. This is of 

 Magdalenian age. In V Antliropologie for Novembre-Decembre 1899, 

 p. 671, there is a paper by M. Henri Quilgars on Industrie des Silex 

 a contours Geometriques fi'om the neighbom-hood of Guerande (Loire 

 Inferieui'e). These are not quite so regular in form as those figured 

 by me from Mr. Gatty's collection, and some of the specimens show a 

 concavity on the sides apparently worked. The author is inclined to 

 consider some of them of GaUo-Eoman age. 



By permission of Mr. Gatty, I show figures of six specimens from 

 his collection, three English, see figs. 35, 36, 37, No. YIII., and three 

 Indian, for comparison see figs. 41, 42 and 43, No. YIII. The 

 four examples shown in figs. 38, 39, 40, 44, are of specimens 

 which he presented to me, and figs. 45 and 46 are Irish examples from 

 my own collection. It will be seen by the figures how great a resem- 

 blance the Indian specimens have to the English, fig. 35 of the one and 

 42 of the other being particularly alike. The English example shown 

 in fig. 44 is also very similar to fig. 45 found in Ireland — the straight, 

 almost perpendicular di'essing across the back, and the sharp cutting 

 edge on the opposite side being almost identical, as will be seen by the 

 sections given below the figures. Implements like these with sharp 

 edge on one side I should say were minute knives, and those having 

 both sides dressed, like figs. 35, 36, 37, etc., were probably borers, but 

 either of these kinds may also have been used in scraping. 



I show on No. YIII., figs. 48, 49, 50, 51, four small scrapers fi'om 

 Bundoran, county Donegal. One of these, fig. 51, is of fiint, the other
