rod which serves as a handle to this circular plate is so short, that it 

 does not prevent the cover of the cylindrical vessel from being put 

 down into its place." 



Two-thirds of an inch answers best for the coffee in powder before 

 it is pressed together, and the pressure should be such as to reduce 

 the thickness to something less than half an inch.

As these heights are nearly equal, the Count recommends that the 

 strainers be all made of the height of 5\ inches, and suspended in 

 their reservoir at such a height that their bottoms be above the per- 

 colated fluid when all has passed through. 



" The reservoir and its boiler, he then observes, must be soldered 

 together above, at their brims : and the reservoir must be suspended 

 in its boiler, in such a manner that its bottom may be about a 

 quarter of an inch above the bottom of the boiler. 



" The small quantity of water which it will be necessary to put 

 into the boiler, in order that the reservoir for the coffee may be sur- 

 rounded by steam, may be introduced by means of a small opening 

 on one side of the boiler, situated above, and near the upper part of 

 its handle. 



" The spout through which the coffee is poured out passes through 

 the side of the boiler, and is fixed to it by soldering. The cover of 

 the boiler serves at the same time as a cover for the reservoir, and for 

 the cylindrical strainer; and it is made double, in order more etfec- 

 tually to confine the heat. 



** The boiler is fixed below to a hoop, made of sheet-brass, which 

 is pierced with many holes. This hoop, which is one inch in width, 

 and which is firmly fixed to the boiler, serves as a foot to it when it
