在回答先生沃森的询问包含在你的最后一个号码，我可以说，在英国协会会议在埃克塞特，在1869年，我读了一篇论文在上述标题下（见菲尔。Mag.for September，1869），其中一些比较实验是在充分的阳光下燃烧的蜡烛，也在一个黑暗的，壁橱。采用这种实验模式是因为它允许通过称重来测试结果。使用相同品牌的蜡烛，硬精子蜡烛比复合蜡烛受温度变化的影响更小。蜡烛被允许燃烧四个小时。我给一个结果：-在黑暗中（温度。81° F.）每支蜡烛损失544格令，即每小时损失136格令。
IN answer to Mr. Watson's inquiry contained in your last number, I may state that at the meeting of the British Association at Exeter, in 1869, I read a paper under the above title (SeePhil. Mag.for September, 1869), in which some comparative experiments were made on candles burning in full sun-shine and also in a darkened, closet. This mode of experiment was adopted because it allowed the results to be tested by weighing. Candles of the same make were used and hard sperm candles preferred as being less affected by variations of temperature than composite. The candles were allowed to burn during four hours. I give one result:—In the dark (temp. 81° F.) each candle lost 544 grains, or 136 grains per hour.
