You're most welcome!
I was reminded of this resource by a book I'm reading now: The Black Count, about the father of Dumas pere and grandfather of Dumas filles --- a great general, rivaling Napoleon (or, in height as well as glamour and dash, exceeding Napoleon).
It was just a mention, in illustrating the importance of the sugar trade in the 18th century (the general's father took some part in sugar plantation operation but that's a whole 'nother story) the author cites a period apothecary's recipe for a remedy for blindness, which is sugar, pearl, and gold, ground fine and blown into the eye. It seems almost every remedy at the time relied in part on sugar. (Of course in Rocca we prefer the more humanitarian honey.)
