Accordingly I have ventured to new mould the whole fabrick; and hope it will appear, that all the valuable meterials, fcattered through Neumann s, writings are col¬ lected and difpofed with propriety. 1 have added by way of notes, the later dis¬ coveries and improvements made in chemiftry and the arts depending thereon. Much of this part of the work is taken from the writings of others and not a little irom the diaries of my own elaborately.
