SECT. VI. 



This way of flu dying Mineralogy has al- 

 ready fome time ago been entered upon ; but 

 Mr. Pott, at Berlin, has brought it to a greater 

 perfection ; and after him Mr. Cronfledt, in Swe- 

 den, has extended it yet farther, fubmitting every 

 mineral body, that came to his hands, to chemical 

 experiments •, in confequence of which he after- 

 wards publifhed his Effay towards a Syftem of 

 Mineralogy. 



SEC T. VII. 



Thus the greatefl obflacle is removed : the beft 

 method to learn Mineralogy is laid open, in fol- 

 lowing v/hich we are enabled to render this Science 

 more and more perfect. To obtain this end, che- 

 mical experiments are without doubt neceffary ; 

 but as a great deal of the mineral kingdom has 

 already been examined in this manner, we do not 

 want to repeat all thole experiments in their whole 

 extent, unlefs fome new and particular phceno- 

 mena mould ditto ver themlelves in thofe things 

 we are examining •, el it the tedioulhefs of thofe 

 proceiTes might difcourage fame from going far- 

 ther, and take up much of the time of others, 

 that might be better employed. An eafier way 

 may therefore be made uie of, which even for the 

 mod part is fufficient, and which though made in 

 miniature, yet is as fcientifical as the common 

 manner of proceeding in the laboratories, iince it 

 imitates that, and is founded upon the fame prin- 

 ciples. This coniiirs in a method of making experi- 

 ments upon a piece of charcoal with the concentrated 

 fame of a candle blown through a Blow-pipe. The
