An old book I'm reading mentions essence of mereby. I've never heard of this and I am looking for more information.
A book of household instruction from 1838 contains a recipe for making perfume which includes as an ingredient "essence of mereby". Google avails me naught. Any idea what this might be? And if you have a reference source, I'd be interested in learning what that is too because clearly my own shelves are lacking. If I don't find an answer here, I'll reach out to a perfumer's organization but thought a mefite might be joyful for the chance to share obscure knowledge.
