A POPULAR discourse at the Blackpool meeting of the British Association was given on Friday, September 11, by Mr. C. C. Paterson. He chose as his subject “Science and Electric Lighting”, and illustrated his discourse by many striking and spectacular experiments. Through the medium of these experiments, he enabled the audience to picture the present outlook of the scientific worker in the field of electric lighting and how rapidly it is changing. During the last four years, the amount of light that can be obtained from a given quantity of electricity has been increased three times. During this time, it has also been demonstrated that it is possible to make lamps of which the luminous component is at least a hundred times brighter than the brightest filament previously available. These great achievements are rapidly being exploited by industry in Great Britain.
