The televue, or seeing telephone, as it is called, is the invention of J. B. Fowler, of Portland, Ore. Mr. Fowler is not a scientist, but a humble workmen, who has been classed as an inventor from the days of his boyhood. His latest production in that line consists of a device used in connection with an ordinary telephone by means of which one may distinctly see the features of the person with whom he is carrying on a conversation. While it is admitted that the televue is still in a crude state, it is said by those who have seen it, to be not more so than was the telephone when on exhibiton at the Centennial Exposition in Philadelphia.

For a cement for sticking leather fillet on brass patterns, melt together eight parts of beeswax and two of rosin ; cut into strips when cold and apply with a sticking tool of the proper radius. A steel ball of the right size stuck on a wire and heated in a bunsen burner is the best. The pattern should be slightly warmed. Superfluous cement may be removed, when all is cold, with a bit of waste dipped in turpentine.

A new industry is being formed on the boader lines of Barren, Edmondson and Hart counties, Ky., for the development of large deposits of onyx which have been found in several caves of the State. In one cave is said to exist the largest deposit of oxyx in the world, it being 200 feet in circumference and 75 feet high. The onxy is white and said to be of the finest quality. In other places the deposits are red, yellow, black and varied-colored onyx.

Electricity is not a form of energy, any more than water is a form of enery, says Sir Oliver Lodge. Water may be a vehicle of energy, when at a high level or in motion; so may electricity. Electricity cannot be manufactured, as heat can; it can only be moved from place to place, like water, and its energy must be in the form of motion or of strain. Electricity under strain constitutes a current and magnetism; electricity in vibration constitutes light.

The power obtainable by a given stream of water is, within a small factor due to friction, directly as the head, but the water is not always applied to the greatest advantage.

To make a gas engine noiseless, the following simple device can be introduced by any one at a small expense, says an English journal. A pipe split for a distance of about 80 inches is attached to the end of the exhaust with the split end upward. Beginning at the lower end of the cut, which may be best made by a saw, dividing the pipe into two halves, the slotted opening is widened out toward the top until it has a width equal to the diameter of the pipe. The puff of the exhaust spreads out like a fan, and the discharge into the open air takes place gradually. The effect produced is said to be remarkable, but it depends somewhat on the fiber of the tube.

A new method of denaturing alcohol so as to render it unfit for drinking purposes is to charge it with acetylene gas. This gas is commonly stored by dissolving it in acetone, an alcohol-like liquid which has a partial affinity for acetylene. All alcohol possesses this affinity to some extent, and ordinary grain alcohol, which is by many regarded as the future fuel for internal combustion engines, will absorb considerable quantities of the gas. Alcohol thus denatured is rendered totally unfit for drinking, while at the same time its heating power, or calorific value is increased instead of diminished, as is the case of practically all other denaturing agents. Grain alcohol now sells for 16 cents a gallon in Holland, where there is no tax upon its use for industrial purposes, and denatured with a small amount of acetylene - too littleto increase its cost materially - its power value is said to be much above that of gasoline.

Tantalium as material for tools may have a wonderful future. This substance is the metal employed by Siemens and Halske for their new incandescent lamp filaments. There is a report that laboratory experiments have shown it to possess a hardness comparable with that of the diamond, and great toughness also. When, after much work, a piece of the pure metal was for the first time produced, a sheet about 1 millimetre (.039 in.) thick was hammered from it. An attempt was made to drill this, and, other means failing, diamond drill was used. Constant work for three days and nights at the rate of 5000 revolutions per minute resulted in a depth of only 1/2 millimetre, and the drill was so badly worn that the experiment was discontin-tinued. Since tantalum is thoroughly unmagnetic, it would be of use where a metal as strong as steel is needed, but where the magnetic properties of the latter are objectionable. The fusing point lies at about 2300° C. (4172° F.) its specific gravity is from 14 to 17, and in color it resembles platinum. In the form of wire it sustains a load of 90 kg. per square millimetre, or 128,000 lbs. per square inch.

It is generally figured that 1 cubic inch of water, when evaporated under atmospheric pressure, will make 1 cubic foot of steam.

A column of water 2000 feet high, no matter what the length of the pipeline, will develop a static pressure of 866 pounds per square inch.

Two elaborate telephone systems are being installed on the steamer Dakota, now under construction for the Great Northern Company. This will be the first ship to be equipped with telephones.

The main use of metallic arsenic is in the manufacture of shot. When arsenic is added to lead and dropped from a height, the shot assumes a rounded shape which otherwise, with but the pure metallic lead, would assume a tailed form.

Concrete is not a new, nor even a modern substance. Important structures built by the old Romans before the commencement of the Christian era are today sound and solid - for example, the dome of the Pantheon in Rome, 142 feet in diameter.

To fasten paper labels, etc., on iron, use a cement made asfolllows: Over a water bath dissolve 4 parts by weight of gelatine in 3 parts of water; while stirring add 1 part of acetic acid, 1 part alcohol and 1 part of pulverized alum. The metal must first be rubbed with a bit of fine emery paper.

A curious property of Portland cement, said an engineer, is that when a package of cement is opened and emptied it can be dusted out so that the bulk is increased quite one-third. I will defy anyone once hav-tng emptied a barrel of cement to replace the whole of it in the same barrel without considerable effort.

By short circuit is meant a direct connection by accident or design of the positive and negative leads of a supply circuit or dynamo by a conductor of low resistance. This allows an excessive current to flow, which, owing to the heat produced, will fuse the leads and possibly overload the generator supplying the current and thus destroy its insulation.

The first patent issued by the United States Patent office was on July 28, 1837. During that year a total of 106 patents was issued. During 1964 the number of patents issued was 30,267, a total to the first of January, 1905, of 748,567. This number has been since increased up to June 6, 1905, to a total of 791,991. At the present rate the number of patenls issued during the calendar year, 1905, will exceed 30,000.

While working upon a foolish theory that he could convert silver into gold, Nicholas Brandt, a German chemist, in the year 1732, made the discovery of phosphorous. Evidently he did not place much importance in his discovery, as he continued in his experiments to transmute silver into gold. Being thus engaged, other chemists made a study of phosphorous, and it is to the chemist Boyle that the world gives credit for the discovery.

The 353 foot-chimney of a smelting plant in Denver, Col., has been used to support the atennsc of a De Forest wirelees telegraph station

Time in Manila, P. I., is 13 hours later than at Wash-ngton, and 14 hours later than at Chicago.

Donaid Murray of England has devised a printing telegraph which will not only print telegrams at the receiving station but can be attached to a linotype machine and will set type without human aid. The inventor states, however, that the expense of the typesetting system is such that it is not likely to supersede the manual operation of linotype machines.
