Hence the elasticity of the wire plays the same part as the weight of the beam does in the common balance. This would seem to settle the whole case, for if the encyclopedia says it has no reason to be, then, like the edict of the Mikado, it is as good as dead, and if that is the case, "Why not say so?" On the contrary, the torsion balance seems very much alive.
Another Roman surgeon, Heliodorus, not only describes the use of the ligature in stopping hemorrhage, but also the practice of torsion twisting smaller vessels, which causes their lining membrane to contract in a manner that produces coagulation and stops hemorrhage.
"The tarnal old thing's bewitched, I believe," said Frank, allowing his sister to interfere and quietly untwist and turn right side out the various parts which he had put wrong by all sorts of torsion. "I'll teach Boston chaps to know that there are some things they can't have for money!
"Like the wings of birds; and have the same forward and downward stroke, by a direct piston action. The impetus is given, after a descent in air which I effected by starting from a height of six feet only by a combination of heated naphtha and of india rubber under torsion. By steam alone, in 1842, Philips made a model of a flying-machine soar across two fields.
The ordinary causes of this pre-judgment or mental torsion are an habitual intellectual outlook resulting from education and surrounding influences, and a mental laziness which fails to question its own attitude and to pursue principles to their logical conclusions, and problems to their solution.
The power of these wires, if properly prepared, is most remarkable, being able to reverse their polarity under torsion, as if they were completely saturated; and they preserve this power indefinitely if not touched by a magnet.
Guards were pacing the walls, and a squad of the younger men were engaged in setting up the artillery machines for hurling stones so as to command the open space in front of the north gate. New ropes were being fitted to the torsion levers, and an ox-cart loaded with ammunition, in the shape of rounded boulders, creaked noisily through the gateway.
Knowing that by torsion we can rotate or diminish magnetism, I was anxious to obtain by its means a complete rotation from north polarity to neutrality, and from neutrality to south polarity, or to completely reverse magnetic polarity by a slight right or left torsion.
Dr. de la Rue concluded his interesting discourse by exhibiting some of the finest tubes of his numerous and unsurpassed collection. Engineering Coulomb's torsion balance has been adapted by M. Baille to the measurement of low electromotive forces in a very successful manner, and has been found preferable by him to the delicate electrometers of Sir W. Thomson.
Small polypi may be treated by torsion or astringents. If cut, there is likely to be a subsequent abortion. Large polypi removed toward the close of pregnancy will cause hemorrhage. Carcinoma of the cervix should be removed at once. A few of the examples on record of operations during pregnancy of special interest, will be given below.
