monuments also represents that of the localities in which 

 the "chank" is commonly used, even in modern times. 



[Since this was written, Mr. J. Wilfrid Jackson has 

 called my attention to the important evidence relating to 

 the use of pearl-shell, the exploitation of purple, and the 

 importation of Red Sea cowries, in Ireland and elsewhere 

 in the British Islands (Edward Collier and Robert Standen, 

 Joum. of ConcJwlogy, April, 1896, pp. 188 and 189: also 

 J. W. Jackson, same Journal, April 1st, 1912). For the 

 evidence of the use of purple in Gibraltar, see Duckworth, 

 Joum. Roy. Anthr. hist., 191 1, p. 363 ; and in New Zea- 

 land, see Colenso, Trans. N. Zealand Inst., 1881, p. 57. 

 The importance of this evidence in further corroboration 

 of the identity of the motives and the methods of the 

 culture-distributors who wandered respectively East and 

 West from the Eastern Mediterranean is obvious. I hope 

 that Mr. Robert Standen and Mr. Wilfrid Jackson will 

 undertake the interesting task of following up these clues 

 afforded by shells and present the results to the Society.]
