    This historic book may have numerous typos and missing text. Purchasers can download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1838 Excerpt: ...a bell-glass, suspended over tne steady flame of a stearine candle, had a white powder (the oxide of arsenic) deposited on its sides. The conclusions at which the Committee arrive are, that the candles in question have been manufactured for the last two or three years in this country, and that the practice of making them is on the increase daily. The Committee conceive that the vapour given off from them during combustion is likely to be prejudicial. In closing their report, the Com mittee express their wish to be of service to the public in a matter of so much importance, in the absence of all medical police in this kingdom, the only country in Europe where the public health is so little regarded by the governing powers. ' Dr. A. T. Thomson said, there was a test for these candles, which, after repeated and extended observations, he had found to be a correct one; the surface of the pure candles, around the burning wick, was always a level space, while in the stearine, arsenicated candles this space always formed a hollow cup, with a thin, transparent, ragged edge. Though on his being appointed on the Committee, he had some doubt respecting the injurious effects of the candles in question, the Report had fully satisfied him on the subject. Mr. Barclay, a manufacturer of candles, stated that this test might be fallacious, other kinds of candles occasionally giving the same appearance during combustion. Dr. A. T. Thomson believed the appearances to be peculiar to these candles; the ragged rim in other candles, all kinds of which he had burnt, was confined to one side of the flame, and this opposite to the current of air from a door, or other draught. The test, ot course, was to be only looked upon as a collateral one, but many of the other tests being present.
