    Chisholm's Method of Disinfecting and Deodorizing or Treating Sewage, $c. thousand eight hundred and fifty-eight, in the twenty-second year of Her reign, did, for Herself, Her heirs and successors, give and grant unto me, the said John Chisholm, Her special license that I, the said John Chisholm, my executors, administrators, and assigns, or such others as I, the said John Chisholm, my executors, administrators, and assigns, should at any time 5 agree with, and no others, from time to time and at all times thereafter during the term therein expressed, should and lawfully might make, use, exercise, and vend, within the United Kingdom of Great Britain and Ireland, the Channel Islands, and Isle of Man, an Invention for “A Method of Disinfecting and Deodorizing or Treating Sewage and other Matters, and 10 Structures and Places,” upon the condition (amongst others) that I, the said John Chisholm, my executors or administrators, by an instrument in writing under my, or their, or one of their hands and seals, should par¬ ticularly describe and ascertain the nature of the said Invention, and in what manner the same was to be performed, and cause the same to be filed in the 15 Great Seal Patent Office within six calendar months next and immediately after the date of the said Letters Patent. HOW KNOW YE, that I, the said John Chisholm, do hereby declare the nature of the said Invention, and in what manner the same is to be per¬ formed, to be particularly described and ascertained in and by the following 20 statement thereof, that is to say :— This Invention consists in the application of electric or galvanic agency to the sewage or other matters or to the locality to be disinfected or deodorized, whereby foul gases are decomposed, noxious air or matters purified, and in certain cases the resulting products may be turned to useful account. 25 Having thus set forth the nature of my Invention, I now proceed to describe how the Invention may be practically carried into effect; but in so doing I do not restrict myself to any particular method of or means for obtaining and applying the electric or galvanic agency which I employ, as various modes and apparatus or contrivances may be adopted for the purpose. 30 The application of electricity or galvanism, as proposed by me, to the vitiated and noxious gases contained in confined places, produces effects analogous to those of ozone acting naturally on matters exposed to its in¬ fluence, in situations where the atmospheric air has free access and circulation; but as this natural action is neutralized or destroyed in localities where free 35 access of atmospheric air is prevented, as in crowded towns and structures, drains, sewers, and other confined places, I propose, according to my Invention, to apply electric or galvanic agency to them and their contents, and thereby
