TROPON.

The general qualities of this preparation may be briefly enumerated. It is a light brown, almost tasteless powder of small volume, made of raw vegetable and animal materials. In a dry state it is not perishable, is not hygroscopic, and is not soluble in water. The proportion of pure albumen which it contains is, according to our investigation, 90.44 per cent.; computed on a dry basis about 95 to 99 per cent.

The advantages claimed for it by its inventor are as follows: Unlimited durability, tastelessness, little volume, low price, and, above all, it is easily digested.

The essentials of an artificial albuminous preparation, intended as a substitute for the natural albumen of the regular food, are: (1) that it should be able to supply the whole of the albumen necessary for the human body by itself; (2) that it should be capable of being entirely utilized. That Tropon entirely fulfills these requirements is shown by tests already made.

No contraindication against the administration of Tropon for nourishment has been found in any state of illness; its use is, therefore, in no way limited nor need it be restricted. It may be given as food to children as well as to adults.

In administering Tropon, being insoluble it had best be added to thick soups, purées and such like dishes, and this may be done in such a manner that patients do not become aware of it. In milk it must be evenly distributed and stirred very carefully; with chocolate or cocoa large quantities may be simply mixed or boiled without the addition being noticeable.

A tablespoonful of Tropon is equivalent to the amount of albumen that is present in 4 oz. of the finest meat free from fat and sinews.

The nitrogenous matter in this preparation is only contained in albumen so that the nitrogenous excretion in the urine which follows its use can only be accounted for by a larger change of albuminous substances in the body. This explains the increase in weight of the body when Tropon is taken instead of meat.

The new product has been used by leading German practitioners, with the most satisfactory results, as a food in the treatment of tuberculosis and is well borne by such patients as are suffering from this complaint. It rapidly increases weight without causing digestive disturbances and is undoubtedly a very valuable remedy in the treatment of the consumptive and has been so proven in extensive clinical experiments.

THE NEW UNDERWEAR.

The fabric, made of Egyptian cotton, has a coating of pure silk, and is called "Kotedsilk," a name most aptly selected and convincing. The material is warmer than wool, lighter in weight and will not irritate the skin. Neither will it shrink in washing. Both the substances used in its manufacture are very durable, hence this fabric will be found to wear better than all wool or silk. Physicians know that body contact with silk allays nervousness, and silk being a non-conductor of electricity, warmth and vitality are equalized by the wearing of "Kotedsilk" garments. Persons afflicted with rheumatism report that they have been benefited by its wearing.

This underwear for children and infants settles the vexed question of keeping the little people thoroughly protected from the cold without so bundling them up as to interfere with their ease of movement. Children appreIciate the soft, sill:en surface as much as their elders do, and it will be found that colds and bronchial trouble will be materially alleviated by the substitution of Kotedsilk for the woolen garments usually worn by children.

"Are you a vegetarian?"

"Yes. By proxy. I have always insisted that cows and other food animals should be strictly limited to a vegetable diet."

Erosions of the os uteri or granular os are a quite common condition and usually yield rapidly to appropriate treatment. After cleansing the vagina and cervix a strong solution of sulphate of copper, nitrate of silver or some caustic acid should be applied, and after the surface has been again cleansed a Micajah's Medicated Uterine Wafer is to be inserted in order to keep the parts in an antiseptic condition and to promote healing. Curetting is sometimes necessary.

Much interest is being taken by the physicians of this city in a case of almost total deafness, which has been nearly if not entirely relieved by an inexpensive invention belonging to F. Hiscox, of 853 Broadway, New York City. As every known device, and the most skillful treatment, had failed to afford relief, the case was believed to be incurable, and the success of this invention, which is easily and comfortably adjusted and practically invisible, is considered a remarkable triumph.

Medical Progress in the
Nineteenth Century.

The material progress of the century now closing is one of the marvels of the ages. Steam and electricity, with their resultant improvements in rapid communication and rapid transit have contributed to this new status. The increase of wealth is so enormous as to stagger our power of appreciation. With
