954 On the Salts, called Puckwah and Phool-Kharee. [No. 120. 



3. That even now our knowledge is evidently very imperfect, and 

 the probability is, when we recollect that since our possession of these 

 provinces Mr. Stephenson seems to be the only practical chemist 

 who understood what he saw about him, that" there are many more 

 things for a chemist to discover. 



4. I have, it will be observed, indicated some sources which can 

 only be taken into account as make-weights ; what may be the aggregate 

 amount of all these we know not. It may be much larger than we sus- 

 pect. 



Postscript, 



Fortunately I had not seen the report of the officer deputed to enquire 

 on this subject before handing mine to you ; and indeed I had but a 

 few minutes' conversation with him before entering on the investiga-

 I say "fortunately," because it is most satisfactory to me, as it must 

 be to the Board, and to him, that in so intricate and uncertain an in- 

 vestigation, two reports founded, the one upon local inquiry, and the 

 other upon chemical and statistical deductions from a mixture of cer- 

 tain and uncertain data, the main results sliould so closely approximate. 

 To shew how nearly they do so, and where they differ, I set down 

 briefly in parallel columns, our results, following the order of my sec- 

 tions, and add my remarks at the end of each, where required.

PUCKWAH. 



Report says '*Tar. 38. Is inform- I shew, that the sample analysed 

 ed that good Puckwah contains 10 contains 75 Culinary Salt, no 

 Nitre, 53 Culinary Salt, 21 Kharee, Nitre, 21 Kharee, and 15 extra- 

 Sulphate of Soda, &c. 16 various neous Salts. 

 Salts." 



" Par. 60, contains Nitre." 



Note. — It is possible, and indeed most probable, that every sample 

 differs, and in this the report agrees with me. But I should exceed-
