PHLOGISTIC THEORY. 139 



again, "This work obtained very little reputation 

 or estimation, or, to speak ingenuously, as far as I

 a supplement to his work, in which he showed how 

 metals might be extracted from mud and sand. He 

 offered to execute this, at Vienna ; but found that 

 people there cared nothing about such novelties.

 notice, and led to controversy on the "so-called 

 sulphur." The success of the experiment had been 

 doubted, which, as he remarks, it was foolish to

 decide the point by experiment ; and finally, it had 

 been questioned whether the substance obtained by 

 this process were pure sulphur. The originality of 

 his doctrine was also questioned, which, as he says, 

 could not with any justice be impugned. He pub-

 at various intervals, as the Specimen Beccherianum 

 in 1703, the Docuinentum Theorice Beccheriance, a 

 Dissertation De Anatomia Sulphuris Artificialis ; 

 and finally, Casual Thoughts on the so-called Sul- 

 phur, in 1718, in which he gave (in German) both
