Notes TO THE ILLUSTRATIONS. 
1. I have rejected photographic reproduction, because I 
have seen that this process applied to quartz specimens is 
inadequate to render detail. For confirmation see Dr. 
Sarasin’s ‘‘ Steinzeit auf Ceylon.” 
2. The figures attached to my Paper have been drawn with 
the utmost care by Mr. G. M. Henry of the Colombo Museum, 
to whom my best thanks are due. The stones are so far 
accurately reproduced in their natural size that an implement 
laid upon the drawing exactly covers it. It will be at once 
perceived that this system implies an unavoidable incorrectness, 
inasmuch as the thickness of the stone, sketched in by eye, 
encroaches upon and so diminishes its actual breadth. I have 
thought it better to put up with this designed inaccuracy than 
to conceal the back from view altogether. Considerations of 
space and labour preclude us from presenting each stone under 
four aspects. 
3. The last specimens figured, viz., Nos. 880 to 922, are 
not from Ceylon; nor are they of quartz, but are of obsidian 
from Uganda. They are inserted here partly for purposes oi 
comparison, partly because, as far as I am aware, no similar 
specimens have yet been described.
