of tears, with strong sense of heat. When it was applied to my ears, a sense of heat, and a considerable noise were the effects produced.[61] 3. It is asserted by physicians of the Continent that this gas is extremely useful when applied to old, ill-conditioned, and irritable ulcers, as soothing and promotive of healthy discharge, and ultimately of cicatrisation. 4. Although the breathing of this gas is as mortal as that of the Grotto de Cane, yet if diluted with plenty of atmospheric air, it is thought that it might prove serviceable in some states or stages of phthisis, asthma, &c. 5. The action of this gas on the eyes and ears I have already mentioned. Its remedial agency is much extolled in certain disorders or diseases of those organs, attended with atony or morbid irritability of their nerves and structures. 6. These baths are chiefly employed in cases of paralysis attended with stiffness, feebleness, or spasmodic movements. 7. In chronic, inveterate affections of a gouty or rheumatic nature—chronic sores—glandular swellings—and various cutaneous complaints, the gas baths are applied, and, as is affirmed, with success. 8. In uterine affections, irregularities, &c. attended with torpor, debility, and irritability. Upon the whole I am disposed to think that the gas baths are active agents, and that they may be made useful ones, when carefully applied. MUD BATHS. Among the novelties—transcendentalisms, or, as some would call them, extravaganzas, of Germany, the MUD BATHS deserve the “passing tribute” of a short notice. But alas! there is “nothing new under the sun”—or under the earth. To the mud of the Nile and the Ganges, virtues almost miraculous—even the creative power of life—have been attributed, time immemorial. Who does not know that the life of MARIUS was preserved by a mud-bath in the Minturnian marshes?—The instincts of animals, too, are not to be overlooked: We all know the extreme tenacity of life possessed by eels—owing perhaps to their frequent use of mud-baths. Swine are proverbially subject to cutaneous complaints, especially measles; to prevent or cure which, Nature seems to prompt the daily employment of mud-baths, in the Summer season. A remarkable instance of the force of instinct is afforded by the Indian buffalo. That animal immerses himself daily, during the hot season, in mud, up to the very nose; by which means, we may conclude that he avoids the jungle fever, or cures himself of liver-complaints. The alligator offers another example. When he has swallowed a buffalo or a tiger, he buries himself up to the nose in mud, on the oozy shores of the Ganges, no doubt for the promotion of digestion. It is unnecessary to multiply the virtues of mud-baths. Those who desire ocular proofs must repair to Franzensbad in Bohemia, where they will see—not mud but bog-baths in perfection; though they are now also got up very well in Marienbad, Carlsbad, Teplitz, and other fashionable spas.
