Thames Tiniiwl. — Tlie C'oin])any liiivc oljtaiTicd aiintlier Act of Parliament, 

 which empowers them to purchase the [iroperty on tlie Xlichllesex side of the 

 river necessary' for the apjiroaclies ; the worlcs will now proceed with ra]tidity. 

 The tunnel is eompleteil to within 50 feet of the wharf at \Viippiug, and 

 pre])arations are making lo commence immediately tlie sinking of the shaft 

 on the Middlesex side of the river. The formatiim of the new shaft, as well 

 as the remaining jiortion of the tunnel, will he carried on at the same time, 

 ami it is expected thai in aho\it four months they will he completed. Not 

 less than 150 workmen are at jirescnt engaged in finishing the interior of the 

 western arch roadway, preparatory to its heing opened, in the first instance, 

 as a thoroughfare for foot passengers. 



To consume /lie smoke from a boiler furnace. — Let the fresh coals he ])iit 

 into the furn.ice as near to the door as possible, and leave the door 0])en for 

 a space of two or three inches to allow cold air to enter, this will keep down 

 the greater part of the smoke which will he consimu'd ; the .same may he ap- 

 plied to marine engines. This method will he found as efficacious as any 

 patent that has yet heen taken out. M. 



Siifrh/ I'airr lo Sleam Boilers. — At a meeting of the Socielv of Arts, on 

 ■Wednesday, May 6tl), llie gold Isis medal «»s a« arded to Mr. ItoLert M-Ewen, 

 for a mercurial gauge vi liich answers the double purpose of an indicator of 

 steam-pre.ssnre and a safety-valve for engine boilers. The novelty of the in 

 venlion consists in llio eni|>loymcnt of a mereiirial tube as a safe-vent for the 

 steam. tJicse tubes ha\ing hitherto been used only as indietitors of pressure, 

 and of a length suflieient to allow the steam to acijuire a dangerous degree of 

 pressure, without giving any other notice uf the fact than what may l)e ob- 

 .served by the eye. As the action of Mr. AbEwen's safety-valve ilepends on 

 a purely jilii/sleiil principle, viz., the oppcsilion ot the clastic force of sle.ini to 

 the stjitie pressure of mercury ^\itI)OUt a nierhonieal ob.struction of any kind, 

 it allbrds a free vent for the steam when its pressure exceeds the limit, cor- 

 responding to the length lo which the lubes are adjusted, according to the 

 strength of the boiler. 



I}iirm Coal. — Dr. Hutchison, of llie Madras artillery, has dra«n up a report 

 on the coal-fields recently discovered in the vicinity of Mergui. by h liich it 

 apiiears that this coal is easy of access, lying at m," great deiilli beneath the 

 .surlaee, so lliat .shafts may be sunk wiihuut' difficulty. For its emiveyanee 

 there seems to be every facility, the river being adjacent, and a land carriage 

 of one mile only being required. 1 1 is not stated wlietber the ipiality of the 

 eoal has been tested bv experiment, but we presume it to be the same of 

 which Dr. Ileifer spoke so highly in his communications. .Steamers will 

 begin to plv bet\veen the difl'erent ports in the bay of Bengal : and the imme- 

 diate cotil dejiols between the Presidencies and .Suez will be more plenlitully 

 supplied, and at a cheaper rate. The eflect these circumstances will produce 

 on the destinies of India can se.ircely be estimated. — Ea.it Intliu Magazine.
