What reading level is Cantor Lectures On the Modern Methods of Artificial Illumination Delivered Bef book?
To quickly assess the difficulty of the text, read a short excerpt:
It is remarkable to reflect how com- paratively stationary the manufacture of can- dles seems to have been until the last century, when the production of stearine and the ingenious invention of a wick that did not require snuffing made the candle a more practical article ; it is, however, still worthy of remark that one of the witnesses (a member of a prominent firm engaged in the candle- making industry) examined before the Com- mission on the standard candle of this country so late as 1881, c...onfessed that he had never contemplated any tests of illuminating power. The treatment of the wick, the quality of wax, and other details, were the subject of very careful attention, but it hardly seems to have been adequately realised that the main busi- ness of a candle was to give light.
Dishes of liquid oil and fat were employed even by the most ancient nations ; we find that they were used mainly for purposes of ornament rather than for the purpose of pro- viding actual illumination. Indeed, this use of the oil lamp prevails in many churches at the present day.
