He extinguished the candle by a sharp expiration of breath upon its flame, drew two spoonseat deal chairs to the hearthstone, one for Stephen with its back to the area window, the other for himself when necessary, knelt on one knee, composed in the grate a pyre of crosslaid resintipped sticks and various coloured papers and irregular polygons of best Abram coal at twentyone shillings a ton from the yard of Messrs Flower and M'Donald of 14 D'Olier street, kindled it at three projecting points of paper with one ignited lucifer match, thereby releasing the potential energy contained in the fuel by allowing its carbon and hydrogen elements to enter into free union with the oxygen of the air.

38他猛地朝火苗吹去，把蜡烛熄灭。将两把匙形木椅拖到炉边，一把是给斯蒂芬准备的，椅背朝着面临院子的窗户，一把是自己坐的。他单膝着地，往炉格子里放了些粘着树脂的枝条和五颜六色的纸张，以及从坐落于多利埃街十四号的弗罗尔与麦唐纳公司的堆置场以每吨二十一先令的代价买来的优质阿布拉莫木炭。他把这些都十字交叉地堆成不规则的多角形，划了一根安全火柴，在纸张的三个角落点上火。这样，燃料里的碳和氢这两种元素就与空气中的氧气自由化合，散发出潜在的能量。
