7, On the Advantageous Use made of the Gaseous Escape from the 

 Blast Furnaces of Ystalyfera; by Mr. J. Palmer Budd, (Proc. Brit. 

 Assoc, Athen., No. 1086.) — This communication drew attention to 

 an economical application of the heated gases which are usually al- 

 lowed to escape from the top of the iron furnaces. It appears that the 

 gases vyhich are evolved from these furnaces escape at a temperature 

 which is about the melting point of brass. In the iron works at Ystaly- 

 fera, where the iron is smelted by the use of anthracite coal, advantage 

 has been taken of this in a most ingenious manner. By an arrange- 

 ment, which is in its character exceedingly simple, but somewhat diffi- 

 cult to describe without a model (Mr. Budd's description was illustra- 

 ted by a very nicely constructed one), the hot gas is led off into another 

 channel by means of a strong current generated through a chamber 

 and air-way from a point just below the top of the iron furnace. It is 

 conducted, very little heat being lost in the passage, under the boiler of 

 a steam-engine ; and it is found to be at a sufficiently high temperature 

 to heat the boiler without the consumption of any fuel whatever. 

 Hence an immense saving is effected. Although only one furnace and 

 one boiler has hitherto been adapted to this purpose, it is found to effect 

 a saving of 350Z. a year. We may consequently expect that when the 

 experiment is further extended and more of the furnaces so arranged 

 that this heat may be economized and employed for the numerous 

 useful purposes to which it is applicable in a large establishment, the 

 saving will amount to many thousands annually. This communication 

 is to be printed entire in the Transactions.
