Modern Electrical Inventions. 55 



On the motion of Mr. Gray, M.R.I.A., a similar vote was 

 accorded to the Chairman. 



The lecture was largely demonstrative, and many interesting 

 experiments were performed in the mechanical application of 

 electric force. A formidable array of electric appliances occu- 

 pied the platform, including electric pumps, drills, welding 

 machines, cooking, laundry, and lighting apparatus, &c. There 

 was also a large screen upon which diagrams and pictures, 

 illustrative of the lecture, were shown by the hydro-carbon 

 light, admirably manipulated by Mr. John Brown.
