The following analyses of metals received from Kish in 1925 may be added 



The following analyses have also been made : —

None of these metals has been found to contain antimony. 



Five specimens of bronze, probably of about 1200 B.C., were obtained by Sir 

 Flinders Petrie from tumuli in Bahrein Island. 



Such irregularities in the proportions of tin and sulphur point to a less developed 

 art of smelting than in some of the other groups of specimens analysed. A high 

 proportion of sulphur is evidence of imperfect smelting, whilst the tin varies from a 

 quantity insufficient to harden the bronze effectually to one so high as to make the 

 metal far too brittle. 



Ores from Sinai were examined and found not to contain nickel, and for com- 

 parison with them an ingot of copper from Bir Nasb, Sinai, was analysed : —
