Manufacture of Glass. 591 



8. I beg further to state, that I should have been unable to send 

 you the accompanying bottles, were it not for the practical knowledge 

 I gained whilst Assistant to Doctor Julius Jeffreys some years ago, 

 with respect to fire bricks, fusible and infusible clays, intense heats in 

 furnaces, &c. when he was establishing his pottery for the manufac- 

 ture of stoneware soda water bottles, and although he was ultimately 

 successful, (for bottles of stone-ware are now made here equal to 

 those imported from England,) still this among other causes tended 

 to involve his affairs irretrievably, as the expences he incurred were 

 upwards of 25,000 Rs. 



9. I have also the pleasure of sending the following specimens : — 



i. Two small crucibles ; these are made of the same materials 



as the pots in which the glass was melted, 

 ii. A piece of the clay, used in making the fire bricks of which 



the furnace was built, 

 hi. A small parcel of the composition, used in making the dark 



green glass bottles, 

 iv. A small parcel of the composition, used in making the light 



green glass bottles. 



10. In conclusion I beg to state, that as these experiments are very 

 expensive, and my means not large, owing to the great competition 

 in the business in which I am engaged, (the manufacture of soda and 

 other mineral waters,) and besides as I have a family to support, 

 I am sorry to say, it is not in my power to continue them any further, 

 the object for which they were instituted having been gained, viz. 

 the production of green glass bottles made of materials the produce 

 of the country, superior to any common green glass bottles which 

 have hitherto been made in it.

 sioner, Agra, dated 3rd September, 1841. 



I beg to acknowledge the receipt of your letter of the third ultimo, 

 with enclosures relative to the manufacture of glass in the Upper 

 Provinces. My delay in answering it has arisen from my having 

 applied to Calcutta for information on certain points connected with
