Again there does seem a tendency for the richer gold to be developed in the south, the proportion of silver rising in the northern mines.

Of course I realize that many more analyses are needed to place these conclusions on a solid basis, but they are interesting and perhaps significant.

In a Third Section I am dealing with some explanations of the chemical action in the quartz lodes which leads to the formation of the enriched deposits of gold, based on an important paper by Emmons on this subjection. As regards the silver, where it contains gold and is free of copper, I share Lucas' opinion that it is a natural product obtained from Egypt itself. All the silver analysis published by Lucas with over 1.0% of copper seem to be 18th or 19th dynasty. The Hetepheres Tomb silver contains 1.0%. Berthelot does not mention copper in the 11th or 12th dynasty silver but as he has up to 31% undetermined material in his analyses, the result is not conclusive.

If you would like me to expand on any of the sections I have mentioned, would you let me know in what direction you are seeking for information.

Yours sincerely,

W. F. Hume.
