Book excerpt: Excerpt from Cantor Lectures on the Modern Methods of Artificial Illumination Naturally, in the short time at my disposal, I cannot hope to deal exhaustively with each special department of the subject of illumina tion so as to furnish information to the expert in his particular line my aim and object will be rather to cover the ground in a general manner, and to show how it is possible to take an impartial interest in all systems of lighting, and to emphasise the true merits of each illuminant for different purposes. I may, however, preface my discussion of this subject by a few remarks on the develop ment of illumination in general. The intro duction of gas for street lighting for instance, dates from about 100 years ago. Previous to this time we had recourse to oil lamps, and it is even said that bowls of pitch were used to light the streets of Paris in the sixteenth century. At the same time the use Of lamps for interior lighting was likewise in a very primitive state. In those days the expression The night when no man can work had avery real significance which we can hardly conceive to-day. Now, in the present age, the tendency is to do more and more work by artificial light and to turn night into day with an ease our forefathers might or might not have envied, but certainly would have' regarded as incredible. Step by step with these developments in lighting have taken place the progress of education and the spread of printed matter, until, to-day, we use our eyes for the purpose of acquiring knowledge to a. Far greater extent than in the times when neither education nor adequate illumination was generally available.
