TRANSLATOR’s
PREFACE.
The pleaſure and inſtruction I received myſelf from this excellent little work of Profeſſor Bergman, inſpired me with a wiſh to make it more generally known to others. A ſyſtem like this, founded upon the constituent principles of things, may be improved, but never can be exploded. Engliſh names are given, but the Latin ones of the original are ſtill retained, as an acquaintance with them will enable the reader more readily to conſult other authors. Blank ſpaces are left after most of the ſpecies, for the convenience of inſerting any new ones that may occur. I have added a few new ſpecies, and ſome notes; the utility of which will be ſufficiently obvious. The table of metals, at page 71, and the index at the end, will alſo, I hope, be conſidered as uſeful additions.
N. B. The centenary (centenarius) of Professor Bergman is equal to 60 Swediſh grains, or nearly 63 Engliſh grains.
