PREFACE* iii 



In England, on the contrary, (a country 

 far richer than France in mineral produc- 

 tions) it receives no encouragement from the 

 public, and few apply to it except gentle- 

 men in the Medical Line, whofe tranfient at- 

 tention is foon diverted by their more direft 

 occupations. The confequences are obvious. 

 The grofleft blunders are daily committed in 

 working our mines and extracting our ores j 

 infomuch, that learned foreigners have re- 

 marked that were it not for their fuperior ex- 

 cellence, and the cheapnefs of fuel, their ex- 

 traftion would infallibly be attended with 

 lofs f, and many ufeful fubftances are daily 

 rejected as ufelefs,

 and well acquainted with the caufe of it, the 

 zealous and learned Doctor Shaiv, and our 

 late eminent Chymift Dr. Le*wis^ have la- 

 boured to promote and facilitate the ftudy of 

 Chymiftry among us, and for this purpofe 

 transferee! into our own language the moft 

 considerable improvements made in their time
