XXXIV. On the constituent Principles of Potash, By 

 Mark Taerg, Esq, of Beeston, near Shrewslury, 



To Mr, Tilloch. ^, ,^, 



SIR, March 21. 



J-N a letter I sent you, dated September 1806*. I suggested, 

 the probability that oxygen was an ingredient in the compo- ' 

 sition of potass. This has b^^en now confirmed by Mr. 

 Davy : and although I was not right as to the quantity, I 

 think J may claim some little merit. The rest, I said, was 

 lime and though here I must have been mistaken as to the 

 quantity, it still remains to be disproved that it does not 

 enter into the composition of potass. May not lime be an 

 oxide of the same metal as potass ; or may not that metal 

 united \Vith other substances form lime? I think the sub- 

 ject worthy of investigation : and unless some one abler 

 than myself takes it up, I shall trouble you with an account 

 of the result of some experiments which I am about to make
