Extract, 'Remarks on Caspar Neumann's paper on ambergris' by John Brown [Browne] Extract from a paper by Browne criticising Neumann's treatise on ambergris (see CLP/11ii/20) and conclusion that ambergris was a type of amber.

Browne repeated the experiments with a greater amount of ambergris and Subject: Chemistry Published in Philosophical Transactions as part of a paper titled 'Editoris recensio experimentorum circa Ambram gryseam à Domino Joh.
