158 New Patents. [Feb. 



M. Oersted states, the exhausted portion of malt ; although there 

 seeras no reason to doubt that it, and indeed any light substance, 

 in a state of minute division, would prove of nearly equal effi- 

 cacy. " The substance employed," says Mr. Bald, " is known 

 by the name of comings, being the radicles of barley produced 

 in the process of malting, which are separated before the malt 

 is sent to market. About a bushel of these is thrown into the 

 boiler ; and when the steam is again raised, an immediate effect 

 is visible ; for there is not only a plentiful supply of steam to 

 produce the full working speed of the engine, but an excess of 

 it going waste at the safety valve. This smgular effect will con- 

 tinue for several days."
