Aluminium Dirt Cheal


 John H. Tollman, metallurgist in little room at 10 Fifth avenue, Brooklyn, says the New York Record CT, has been for many years seeking q method of producing aluminium cheap ly. Surrounded by pots, crucibles, chemicals, electrical apparatus, and bright chunks of metal, Mir. Tollman said
 II have made study of the process used in the factories in the West where aluminium is made, and am satisfied that they are groping in the darS. The process is simple, but it is too costly to bring the metal on the mar ket in large quantities. The clay is placed in a cylinder, where it is ground and mixed with flux that disinte- grates it. Strong currents of electric ity are forced through the clay from dynamos. Aluminium has an affinity for electricity, and it follows the cur rents, solidities and Is separated from the clay. They get about 65 per cent. aluminium.
 My process IS the reverse of this. put the clay in a crucible and subject 1t to an intense heat. The clay is then dissipated with strong current of air from blower, and when it is all gone there will be found in the bottom of the crucible substance which re- sembles slag, but which in fact is alu- minum about 95 per cent pure. No other process approaches this in puri- ty. The cost of this is comparatively trifling, and the metal can be sold at 15 cents a pound at a profit. There is a secret in the process which can not divulge for my own safety. It consists in the Aux which is used to precipitate the aluminium. It is sim pie and cheap. The only expensive things l employ are crucibles and fuel.
 ''l am not through with my experi- ments, and with improved appliances expect to bring the market value of aluminium down to five cents pound. At this figure it will certainly drive many metals out of the market. It may cost little more, but it's advan- tages will more than mterbaance this. Ihave spent thousands of dol lars in making experiments, and have been disappointed many times, but daylight iscloseat hand and the alum mum industry will be more valuable than any other in this country inside the next ten years. In about three months I will begin the manufacture of aluminium on large scale. Cap- italists have tried to buy my secret, but Ihave nothingto sell except alum inum."
 Effects of African Arrow polsor.
 It has been coniecturedt that the fatal effects of African arrow poison arenot always due entirely to the poison it. self and with Q view of determining how far fear and other influences en- ter into the results of it's exhibition, series of experiments in inoculating the lower animals has been proposed. One of the poisons with which the ar rows of the Africans are smeared is q dark substance likepitch. It is strong enough to kill elephants, and is con sidered so dangerous thatits prepara- ton is not allowed in the villages, but IS carried on III the bush, where also the arrows are smeared. The virulence of the poison is remark able: faintness, palpitation of the heart, nausea, pallor, and the break ing out of beads of precipitation all over the body follow with extraordi- nary promptness, and death ensues. One of Stanley's men is said to have died within one minute from a mere pin-hole puncture in the right arm and right breast; another man died within an hour and aquarter after being shot; and woman died during the time she was carried a distance of a hundred paces. The activity of the poison seemed to depend on it's freshness. Tue treatment adopted waste admin an emetic, to suck the wound,
