be extracted, and consequently a proportionate less quantity 

 of them becomes required. By allowing the cofiee to cool 

 in the closed vessel, it may be filtered through paper, then 

 returned into the closed vessel, and heated again, and thus 

 had of the most perfect clearness without any foreign addi- 

 tion to it, by which coffee is impaired. The liquors may be 

 kept for any length of time at a boiling heat, in private 

 families, coffee houses, &c., so as to be ready at the very in- 

 stant called for. 



It will likewise prove of no small conveniency to travel- 

 lers who have neither kettle, nor coffee-pot, nor tea-pot, in 

 places where these articles are not to be procured, as a bot- 

 tle will supply them. 



In all cases means of economy tend to augment and dif- 

 fuse comforts and happiness. They bring within the reach 

 of the many what wasteful proceedings confine to the few. 

 By diminishing expenditure on one article, they allow of 

 some other enjoyment which was before unattainable. A 

 reduction on quantit}' permits indulgence in superior qual- 

 ity. In the present instance, the importance of economy is 

 particularly great, since it is applied to matters of high 

 price, which constitute one of the daily meals of a large 

 portion of the population of the earth. 



That in cookery also, the power of subjecting for an 

 indefinite duration to a boiling heat, without the slightest 

 dependition of volatile matter, will admit of beneficial 

 application, is unquestionable.
