110 New Secondary Cell for Electrical Storage. 



Of the 127,360 acres of selectable land about 50,000 is 

 already occupied by selectors, under the provisions of the 

 Land Act 1869, and about 9000 purchased, leaving a balance 

 available of 68,000 acres. 



I regret that the limited time allowed for the reading of 

 this paper has prevented me giving a more detailed descrip- 

 tion of the area. I trust, however, that the facts noticed 

 may lead to a better knowledge of this portion of the 

 Victorian Cordillera, and I hope shortly to prepare a paper, 

 dealing not only with the geological structure of the area, 

 but its characteristic native vegetation. 



Art. XIX. — On a New Form of Secondary Cell for 

 Electrical Storage. 



By H. Sutton. 



[Eead 9th December, 1881.] 



The great utility of some thoroughly practical method of 

 conserving electric force has caused a great deal of attention 

 to be applied to the subject. No system of electric supply 

 can be considered perfect until some means is used to so store 

 the force generated that it may be drawn off equally and 

 regularly, and this whether the generator be on or off. 



If we take as an example of electric supply the present 

 systems of electric lighting, it is at once seen, should 

 an accident or stoppage take place in the machinery gene- 

 rating the current, the whole of the apparatus, such as lamps 

 or motive machines, would be influenced. Should there be 

 a reservoir of electricity between the generator and the 

 apparatus for utilising the force, this inconvenience could not 

 occur, as the reservoir would then supply the necessary 

 force. 



All the present sj^stems of storing electricity depend on 

 certain chemical changes produced by electrolysis ; the 

 first effective apparatus being that discovered by M.
