Boiling-point
See EBULLITION. Borax is procured by heating boracic acid with carbonate of soda, the carbonic acid being expelled and the boracic acid taking its place. This salt has an alkaline taste and reaction, and possesses the property of dissolving many metallic oxides; hence its use as a flux in the welding of metals. It dissolves off the coating of oxide formed when they are heated, thus presenting a clean surface. See FLUX; SOLDERS.

Bois-Guilbert
Brian de, bre-an de bwa-gil-ber', a preceptor of the order of Templars in Scott's Ivanhoe. He is a powerful, ambitious, passionate man, hard and cruel, the villain of the story. Scott draws a striking picture of Bois-Guilbert: A man past forty, thin, strong, tall, and muscular; an athletic figure, which long fatigue and constant exercise seemed to have left none of the softer part of the human form, having reduced the whole to brawn, bones, and sinews, which had sustained a thousand toils, and were ready to dare a thousand more.... His keen, piercing dark eyes, told in every glance a history of difficulties subdued and dangers dared, and seemed to challenge opposition to his wishes, for the pleasure of sweeping it from his road by a determined exertion of courage and of will. He is the unsuccessful suitor of Rebecca, the beautiful Jewess. Disguised as an outlaw he makes her his captive. When she is condemned to die as a sorceress he pleads with her to flee with him, but is repulsed. In the tournament at Ashby he enters the lists against Ivanhoe, Rebecca's champion, but falls dead at the beginning of the combat. "Unscathed by the lance of his enemy, he had died a victim to the violence of his own contending passions." See Ivanhoe
