RUSTLESS IRON

One of the greatest practical advances in sanitation, of recent years, we believe, is to be found in the production of the rustless iron, shown at this exhibition. Ordinary iron is so treated that it resists oxidation, thus removing the only valid objection that has ever been raised against the use of iron pipes for drainage purposes, namely, that they would corrode and thus become obstructed. The cost of this rustless iron is about 15 to 20 per cent. more than ordinary iron, but its extra durability would soon offset this extra cost.

THE DISPOSAL OF GARBAGE.

The destruction of garbage by fire is now so favorably regarded that it is unnecessary to do more than show the exterior and interior view of a furnace, for this purpose, that was on exhibition.

Consists of oleo-oil and cream or milk. These ingredients, when churned.-the whole being properly 'salted-give the new food product.

The method of producing oleo-oil is as follows: The selected fat is taken from the cattle in the process of slaughtering, and after thorough washing is placed in a bath of clean cold water and surrounded with ice, where it is allowed to remain until all animal heat has been removed. It is then cut into small pieces by machinery, and melted at an average temperature of 150 degrees until the fat in liquid form has separated from the fibrine or tissue, and then settled until it is perfectly clear. Then it is drawn into raining-vats and allowed to stand a day, when it is ready for the process. The pressing extracts the

THE KODAK CAMERA.

Not alone as a "plaything" does the "Kodak Camera" possess claims upon our consideration. It is a wood box, 34x34x61⁄2 inches, covered with fine, black morocco, having in one end a lens aperture, on the top a folding key, a cord and a revolving disc, and on the side a button. When not in use it is enclosed in a neat hand-sewed sole-leather carrying case with shoulder-strap.

The workmanship of every part is of the very best, and the instrument will compare favorably with the finest field glass in finish and appearance.

One end of the Kodak box contains the lens and shutter mechanism and the other end the roll holder for operating the band of sensitive film.

The Kodak reduces the ten or more operations, heretofore necessary to make an exposure with detective cameras to three operations, reduces the weight and bulk in the same proportion, and increases the number of pictures that can conveniently be made on one trip from six to one hundred; and it makes this very decided advance not by any sacrifice of quality of results, but in a way that guarantees a far better average than ever attained under the old conditions.

This is the exact size of a Kodak Picture,

It has suggested itself to us that this little apparatus would prove very valuable to Health Officers and Sanitary Inspectors for the purpose of photographing nuisances, and thereby perpetuating, for future reference, that which those so interested might remove from view.

CORONET WATER-CLOSET.

For this closet the inventor claims that, on account of the peculiar construction of the trap, the contents may be expelled by recourse to the simplest means, clogging and freezing are impossible, and the services of plumbers materially diminished.

When in operation it is placed preferably near a window. Its case is formed "bureau-like" and is provided with a number of compartments into which are entered a series of filtering webs, which are coated with a suitable absorbent, usually gypsum, which has a great affinity for water and fixes the ammonia in the atmosphere, and through these filtering webs the air is forced. The air is taken in at

the window through a hole in the window-strip, A, and passes down a pipe at the rear of the filter case and enters said case below the first or lowest filtering web, illustrated at H. The said filtering webs are so arranged within the case that the air can only escape by passing through them. The air, after passing through the several antiseptics, escapes through apertures in the top of the case and enters the heating chamber proper. This chamber is provided with a lamp for heating the air. The air is here heated to 250° to destroy any living matter that may be contained in the air. While passing through the pipes it becomes cool before reaching the patient, and with an extension, or drum, N, which projects above the chamber, and centrally within this drum is arranged a combustion pipe, which passes through the drum at the top, said pipe discharging the products of combustion produced by the lamp (through pipe M) to the outside of the building at U. To the upper end of the air drum is connected the pure air pipe, F, concealed under the cornice, thence to the head board of the bed, where it is formed into branch pipes, to which are connected flexible tubes, one of which extends to near the patient's head, while the other is of a sufficient length to permit of its insertion beneath any portion of the bedclothes to supply the body with purified air when so desired. Said branch pipes are each provided with a suitable stop-cock whereby the flow of air may be regulated.

Here, we believe, is a "good thing." The inventor claims for it a wonderful potency in the cure of diseases. This aspect we will not discuss, but the moment we set eyes on this apparatus, we felt that we had found the proper way to secure an adequate supply of pure air for our use, when asleep, at night.

We were much interested in an exhibit of felt shoes and slippers, for it is well known that the human foot is one of the most exposed parts of the body and correspondingly susceptible to external influences. To keep the head cool, and the feet warm, is one of the first laws of hygiene; yet, no part of the body has been more habitually ab ised and neglected than the foot, without a healthy condition of
