Light and compact.
The manufacture of these Regulators is now perfected ; each one is thoroughly tested to the highest pressure, and is guaranteed to automatically regulate the pressure of gas so that there shall not be any diminution in light when using either a Single, Bi-unial, or Tri-unial Lantern, for dissolving or effects, whatever the pressure in the gas vessel may be, the same as if gas-bags were used.
No person after once using these Regulators, would ever work Without them, even with a single lantern.
