Of all the soda water we have examined, we have found that made by Mr. Johnson, to contain the greatest quantity of soda. For the purpose of cooling the body during warm weather, and quieting the stomach, which is generally in a state of increased irritation when the temperature of the air is equal or within a few degrees of that of the body, it is preferable to any of the vegetable or mineral acids. * * * * * THE COSMOPOLITE. SISTERS OF CHARITY.[1] All the world, that is, one out of the two millions of people in this great town, know, that the above is the title of a somewhat romantic drama, in which Miss Kelly is fast monopolizing the tears and sympathies of the public by her impersonation of a _Sister of Charity_. To witness it will do every heart good; and this is the highest aim of a dramatic representation. The performance has had the effect of drawing our attention to the original of the character, which is intensely interesting, though at the same time overtinged with romance. Every six weeks' tourist has seen or heard of the _Sisters of Charity_ on the Continent. They are nurses in the hospitals there, but on a system very different from the hireling attendants in similar institutions in England. Indeed, they may be said to have quitted the world to devote themselves to the relief of those unfortunate persons, who people the abodes of misery and distress. They form, it appears, a numerous body, consisting of several thousand members, who are said to perform or superintend the administration of 300 hospitals in France. They are united under several denominations, as nuns of those monastic communities which escaped the storms of the revolution. Many of them are in the prime of life, and though not bound by absolute vows, devote the whole of their time, and even die in the act of doing good. In spiritual matters, they are under the jurisdiction of the bishop of the district in which the hospital is situated; in temporal concerns they are subject to the authority of the heads of the establishment to which they belong; but they are chiefly under the guidance of the superior of their order. They are fed and lodged at the expense of the hospital, and receive in addition, a certain stipend for the purchase of clothes. In the hospital at Lyons, (which forty or fifty years ago, was the only hospital in France which was not in a barbarous state), there are about 150 of these _Sisters_, wearing a uniform dress of dark worsted, and remarkably clean. They receive the trifling sum of forty francs a year for pocket-money, and sit up one night in each week; the following is a day of relaxation, and the only one they have. During the siege of Lyons, when cannon-balls passed through the windows, and struck the walls every moment, not one abandoned her post near the sick.
