Good research. Your quote is from a written account of the man himself. It appears that my source, a secondary one, was wrong about Lord Walsingham suffering a headache from the Whitworth (fluid steel) barrels.

I suppose that it is unlikely, anyway, that a resolute and urbane Victorian sportsman would be complaining, after a triumphal day afield, about something as trite as a headache. His reason for the change to Damascus was more practical.
