Richard,
 
I would suggest you peruse John K. Crellin's "Alcoholism and Drug
Addiction in the 'Nineties: An American in London," British Journal of
Addiction 75 (1980): 153-62, which discusses the role of Oscar C. Dewolf
in establishing the Keeley Institute in London.  The Keeley "cure" for
alcoholism relied on gold as a curative.
