*Not determined. 



t Sample four was received from a New York firm in response to a request for quotations 

 on carbonate of potash, and was represented to be a calcined carbonate of potash. It 

 showed the presence of 29.7054 carbonic acid (coa) which would be the carbonic acid equiva- 

 lent of 93.29^ carbonate of potash, leaving 3.535( of potassium oxide inform;of caustic pot- 

 ash (4.29^ caustic potash). This caustic potash would not be objectionable as the caustic 

 potash in coming in contact with the air would at once absorb carbonic acid and form car- 

 bonate of potash. All of the above samples were of good quality and contained but slight 

 traces of chlorine and sulphates.
