tube. This horizontal spring lid is also applicable to powder-flask 
chargers, however otherwise constructed. 
Projectiles. — Mr. J. Norton , patentee.— This invention has reference 
to projectiles or ignition missiles suitable for igniting any inflammable 
body with which they may be brought into contact. Under one modifica- 
tion, the shell — which is made of any suitable figure externally — is 
charged with liquid phosphorus. This solution is prepared by dissolving 
phosphorus in a suitable quantity of the bisulphide of carbon, and to 
this solution may be added a proportion of benzole, for increasing the 
inflammability of the solution. The front end of the shell is made so 
that it may be pierced in its passage from the gun. This may be done by 
jdacing a plug in the muzzle of the gun, the inner end of this plug being 
pointed or made with a piercer that will perforate the shell. On the gun 
being fired, the shell is impelled against the pointed part of the plug, 
which is driven out by the force of the blow, and does not further impede 
the flight of the shell. In the passage of the shell the liquid phosphorus 
slowly escapes from the apertures, and ignites on coming in contact with 
the atmosphere, and continues burning until the whole of the liquid is 
consumed. 
Inlaying Gold and other Metals in Glass and Composition. — 
Messrs. Wild 8$ Randel , patentees . — When the patentees desire to inlay 
gold or any other metal in glass, they place the metal to be so inlaid 
within a mould, which mould is then placed at one end of a pair of 
pinching pliers ; having melted sufficient glass to fill the mould, they 
compress the pliers, and the metal remains imbedded within the glass, 
which is then annealed, and is afterwards ready for cutting and polishing. 
The glass most suitable for the purpose is the kind known as Bohemian 
glass, as this melts at a lower heat, and takes a better polish, than any 
other description of glass ; but when this is not to be obtained, or when 
they desire to produce a cheaper article, they use the common kind of 
English glass. When they desire to inlay gold or any other metal in the 
composition before mentioned, they prepare the composition by taking 
about four parts of glass and two parts of enamel, which, after being v'ell 
pounded and mixed in a mortar, are placed in a copper mould with the 
metal to be inlaid at the bottom of the mould. They then place the 
mould on a copper plate (on which is placed a thin layer of plaster of 
Paris), and the plate with the mould on it is then placed in an enamelling 
stove, over a coke fire, until the whole is w T ell fused ; it is then annealed, 
and when taken out of the mould is ready for cutting and polishing. 
Cricket-bats. — Mr. J. Cavanah , patentee . — These cricket-bats are 
manufactured with a loose handle, which handle is joined to the blade 
in conjunction with a spring. The loose handle is secured to the upper 
part or mouth of the blade of the bat by a hinge or knee-joint ; attached 
is a spiral or flat spring, made of steel, india-rubber, or any other suitable 
elastic substance, fixed with metal plates and sockets to the blade and 
handle. The spring may be applied or attached to such portion of 
the blade or handle as may be found most desirable, its employment 
preventing the concussion of the ball stinging or jarring the hand.
