M. Ducoetet uses the following process for tempering and magnetizing steel to be used as magnets. Two soft iron pole pieces are placed in the bottom of a water tight vessel and are connected with the poles of a powerful electro-magnet. The vessel is partially filled with water, and oil is poured into the vessel, which floats upon the surface of the water. The red hot bar is then passed through the liquids and comes in contact with the magnets. This softens the steel without depriving it of its power of being magnetized. To Engrave Name on Steel Tools. Coat the tool or article, if made of iron or steel, with a thin layer of wax, draw the name, initials or design through the wax, exposing the metal, and place the tool in a mixture of 6 parts by weight of water and 1 part of sulphuric acid. In a few hours remove, and if etched sufficiently, wash in clean water and dissolve the wax by heat. STOGDEN, MATTHEW. Inventor of the half-quarter repeating mechanism most used in English watches. He died in abject poverty, about 1770, at an advanced age.

Among the Dayaks of Borneo the Ship of the Dead , the vessel which carries the souls of the departed in search of the hereafter, is generally represented as being of the shape of a bird, the rhinoceroshornbill. Accompanying the souls on their journey through the fire-sea are all the stores which have been laid out at the trivah or feast of the dead, and all the slaves who have been killed for that purpose.

Temporal Power
the power which the Pope exercised as sovereign of the States of the Church. Pius VII. was partially deprived of his dominions by Napoleon I. in 1797, and entirely in 1808. The Pope replied by a bull of excommunication; he was then arrested and kept a close prisoner in France till the fall of Napoleon in 1814, when he was reinstated in the government of an undimin ished territory. The temporal power was again attacked in 1848, when Pius IX. was driven from Rome, and a republic was established by Mazzini and Garibaldi. In 1849 General Oudinot was sent by Louis Napoleon, president of the French Republic, to Rome, and his army drove out the revolutionists and brought the Pope back. For 10 years the Pope's power was not attacked, but Cavour (1810-1861) was working steadily for a "United Italy," and in 1870 Victor Emmanuel, King of Italy, took possession of the papal territory, leaving the Pope only the Vatican. An annual donation of 2,000,000 lire was guaranteed to him by the Italian Parliament, but he never accepted it. Also, the power exercised by the Popes in the Middle Ages of excommunicating, and after excommunication deposing or procuring the deposition of a sovereign who had fallen into heresy.

Tenacity
It is easier to pull asunder a bar of lead than a bar of steel of equal dimensions. This proves that the molecules of some solids cohere more strongly than others. A solid is said to be ruptured when it is thus forcibly pulled asunder, and the power that resists this rupture is called tenacity. If we find how much force is required to pull asunder rods of different solids having equal dimensions, we can then determine their relative tenacity. Tenacity is also that quality of cohesiveness in bodies that causes them to adhere to other bodies, as glutinous, stickiness, etc. See COHESION; ADHESION; STRENGTH OF MATERIALS; METALS.

Tenant Right
a term specifically applied to an Irish custom, long prevalent in Ulster, either ensuring a permanence of tenure in the same occupant without liability to any other increase of rent than may be sanctioned by the general sentiments of the community, or entitling the tenant of a farm to receive purchase money amounting to so many years' rent on its being transferred to another tenant; the tenant having also a claim to the value of permanent improvements effected by him. In course of time the advantages of tenant right granted to the Ulster farmers were claimed by the farmers in the other provinces of Ireland, and the custom spread to a considerable extent. At last, under the management of Gladstone and Bright, the Landlord and Tenant Act of 1870 was passed. By it the Ulster tenant right and other corresponding customs received the force of law, and the outgoing tenant became entitled to compensation from the proprietor to an amount varying according to circumstances. The act contained other provisions giving compensation for improvements, but as it did not succeed in doing away with all grievances a fresh bill was prepared and passed under the name of the Land Law Act, 1881, which established a land commission to revise rents, and to fix them for 15 years. This measure has been amended by subsequent acts.
