 Apparatus, inverted hollow cone, to meet the flat-bottomed 

 shallow oval copper basin : he merely says, **it is 

 so constructed as not to be liable to injury but 

 this indefinite remark can hardly be considered a 

 guide to those who, like myself, have not seen his 

 flue-ghye. 



April 1830. 



I venture now to add, with all deference, that 

 after ten months' practice and close observations 

 of the effect of the pottery-ghye, above one hun- 

 dred and twenty of them having been worked 

 throughout each of the six bunds, that it merits 

 the character assumed at the onset, viz. of unex- 

 ampled economy in fuel, yet much comparative 

 quickness in getting up the required heat for the 

 first beat (or kholic), with total absence from smoke 

 and the chemical impurities of copper basins ; 

 much simplicity and compactness of structure, 

 with cheapness and expedition, yet possessing supe- 

 rior durability and cleanliness ; but above all, a more 

 equable temperature of heat, not yet, I imagine, 

 obtained in any other of the Honourable Com- 

 pany's filatures, as far as I have heard ; for I have 

 never seen any, excepting those of Gonatea and 

 Rangamatty, and it is too much to expect that a 

 new invention, having all the advantage above set 

 forth by its partial projector, should not be closely 

 criticised and disputed.
