Hi All,
         Copper Sulfate - Copper Sulphate - different spelling - are they 
the same thing  (and it's just the Yanks who cant spell (just a joke) ?

         As a kid my Dad used Copper Sulphate in animal dips I think. It 
was also called "Bluestone" and came in bags - it was chips or crystals of 
a semi transparent bright blue colour. Are we talking about the same thing?

         Again, as a kid there were rumours (or Old Wives Tales) that the 
army (and  boys boarding schools) added it to the mens/boys coffee as it 
was reputed to control those "urges" that us men are prone to. It was 
reputed to cause "Coopers Droop". I have no idea if there was any truth in 
this or not!

         I see this as rapidly developing into another "off topic" 
discussion :-) - apologies.
