and power, and hypocrisy a trade: to the ghostly specuator we may well apply the lines of Massinger:

Oh, now your hearts make ladders of your eyes,
In show to climb to heaven, where your devotion
Walks upon crutches.

It is, however, fortunate that errors generally assist the development of truth. The progress of the Christian faith was materially forwarded by the absurdities and fallacies of all other religions; and Helvetius has truly observed that if we could for a moment doubt the truth of Christianity, its divine origin would be proved by its having survived the horrors of False theories led Columbus to correct geographic popery. conclusions, and Galileo's discoveries overthrew his own former theories.

MEDICINAL EFFECTS OF WATER.

AMONGST the various means resorted to by quackery to speculate upon the credulity of mankind, simple river or spring water, coloured and flavoured with inert substances, has not been the least productive; and many a time the Thames and Seine have been fertile sources of supposed invaluable medicines. Sangrado's doctrines on aqueous potations have long prevailed in the profession; and it has been stoutly maintained that a water diet can cure the gout and various other diseases. That relief, if not cures, have been obtained by this practice, there cannot be the least doubt. Are we to attribute these favourable results to the effects of the imagination, the beneficial efforts of nature, or the salutary abstinence which this prescription imposed? Possibly they all combined to assist the physician's efforts, or rather aid his effete treatment. Cold water and warm water have in turn been praised to the very skies by their eulogists, and become the subject of ridicule and persecution on the part of more spirited practitioners.

In surgery, water has ever been considered of great utility; it, no doubt, was instinctively used by man to cleanse and heal his wounds. Patroclus, having extracted the dart from his friend Eurypylus, washes the wound; and the prophet Elisha prescribes to Naaman the waters of Jordan. Rivers had

various qualities, and were supposed to prove as different in their action on the economy as the mineral springs which from time immemorial, have been resorted to. These effects may in fact not be altogether doubtful; for, although these salutary streams may not possess sufficient active ingredients to be recognised by chemical tests, yet we know that substances which appear perfectly inert may prove highly active and effectual when combined and diluted naturally or artificially. Moreover, in the effects of watering-places on the invalid or valetudinarian, we must not forget the powerful influence of change of air and habit, the invigorating stimulus of hope, and the diversion from former occupations. To these auxiliaries many a remedy has owed its high reputation; and probably when Wesley attributed his recovery to brimstone and supplication, he in a great measure might have considered rest from incessant labour the chief agent in his relief. The exhilarating effects of the picturesque site of many of these salutary places of resort is universally acknowledged. Montaigne, Voltaire, Alfieri, acknowledged their influence on the imagination. Petrarch's inspirations flowed with the waters of Vaucluse, some of Sevigné's most delightful letters were written at Vichy, and Genlis and Staël were particularly happy in their epistolary elegance at Spa and Baden.

We owe to accident many valuable discoveries in medicine. It is said that several Indians, having used the waters of a lake in which a cinchona tree was growing, experienced the benefit which led to the use of the Peruvian bark; and the thermal properties of the baths of Carlsbad were first made known by the howling of one of Charles the Fourth's hounds, that had fallen in them in a hunt. It has been also observed, in various countries, that particular waters produced various morbid affections; and to this cause have been attributed goitres, cretinism, calculi, and other distressing diseases. The ancients dreaded the impurity of their rivers. The Romans boiled their water in extensive thermopolia, where not only potations were drunk hot, but occasionally refrigerated with ice and snow, and, when thus prepared, called decocta. Juvenal and Martial refer this custom to the Greeks. Herodotus informs us that the Persian monarchs were accompanied on their expeditions by chariots laden with silver vases filled with the water of the Choaspes that had been boiled, and which was solely destined for the king's use:

Athenæus tells us that it was light and sweet. Many ancient coins and inscriptions have recorded these salutary properties of certain waters.

This real or supposed efficacy was scarcely discovered before it became the domain of priests: and common rain or river water became valuable and sanctified when blessed by them: hence the introduction of lustral water. The fluid extracted from the gown of Mahomet is the sacred property of the sultan. The moment the fast of the Ramazan is proclaimed, this holy vestment is drawn from a gold chest, and, after having been kissed with due devotion, plunged in a vase of happy water, which, when wrung from the garment, is carefully preserved in precious bottles, that are sent by the monarch as valuable presents, or sold at exorbitant prices as cures for any and every disease. Thus were the good effects of ablution, especially in wounds, attributed to some secret charm or quality conferred upon it by clerical benediction or the legitimacy of princes. When a quack of the name of Doublet cured the wounded at the siege of Metz in 1553, the water he used was considered to have been of a mystic nature; and Brantome describes his treatment in the following words: "Durant le susdit et tant mémorable siège, était en la place un chirurgien nommé Doublet, lequel faisait d'estranges cures avec du simple linge blanc, et belle eau claire venant de la fontaine ou du puit; mais il s'aidait de sortilèges et paroles charmées, et chacun allait à luy." This Doublet, no doubt, was acquainted with an ingenious treatise on gun-shot wounds, written by Blondi in 1542, in which he strongly recommended the use of cold water; but, as his recommendation was not founded on any miraculous quality, he was forgotten, while Doublet was considered a supernatural being. Previous to this simple and sagacious method of healing wounds, various curious applications were in high repute; more especially the oil of kittens, which the celebrated Paré discovered to his great delight, was prepared by boiling live cats, coat and all, in olive oil, and was until then a valuable secret preparation, called oleum catellorum, and its use, with that of other nostrums, was known under the name of secret dressing.*

* Oil is, however, a useful application to wounds in warm climates. During the retreat of our troops after the battle of Talavera, I found the wounds of many of our men, that had not been dressed for three or four days, pullulating with maggots. This was not the case with the Spanish

This simple mode of dressing wounds, especially those that were inflicted by fire-arms, was a great desideratum; for, up to this era in surgery, these injuries were healed by the application of scalding oil or red-hot instruments, under the impression that they were of a poisonous nature. Paré was one of the first army-surgeons who exploded this barbarous practice. Having, according to his own account, expended all his boiling oil, he employed a mixture of yolk of egg, oil, and turpentine, not without the apprehension of finding his patients labouring under all the effects of poison the following day; when, to his great surprise, he found them much more relieved than those to whom the actual cautery had been applied. In more recent times, armies have been unjustly accused of making use of poisonous balls; and this absurd charge was brought against the French after the battle of Fontenoy, when the hospital fever broke out among the wounded crowded in the neighbouring villages. Chewing bullets was also considered a means of imparting to them a venomous quality. Lead and iron, the metals of which these projectiles were usually cast, were also deemed of a poisonous nature. A sort of aristocratic feeling seemed to obtain in those days; and it is related that two Spanish gentlemen had procured gold balls to fire at Francis I. at the battle of Pavia, that so noble and generous a prince should not fall by the vile metal reserved for vulgar people; and, in the adverse ranks, La Chatarguene, a noble of the French court, had prepared bullets of the same costly material for the reception of Charles V. It was under the impression of this poisonous nature of wounds, that individuals of both sexes, called suckers, followed armies, and endeavoured to extract the venom by suction; the records of chivalry give us instances of lovely damsels who condescended to perform this operation with their lovely mouths upon their damoiseaux; and Sibille submitted the wounds of her husband, Duke Robert, to a similar treatment: indeed, these suckers were chiefly females. May not this practice be the origin of the term leech, applied in ancient times to medical men? Leechcraft was the art of healing. Thus Spenser:

soldiers, who, to prevent this annoyance (which was more terrific than dangerous), had poured olive oil upon their dressings. I invariably resorted to the same practice when I subsequently had to remove the wounded in hot weather.

And then the learned leech

His cunning hand 'gan to his wounds to lay,
And all things else the which his art did teach.

To this day, the custom of sucking wounds prevails among soldiers; and there is every reason to hope, from the experiments of the late Sir David Barry, that the exhaustion produced by cupping-glasses will be found of essential service in all venomous wounds. This practice of suction, no doubt, was known in Greece; Machaon performed it at the siege of Troy. The mothers and wives of the ancient Germans had recourse to the same process. In India the suction of wounds constitutes a profession. It was by this means that the Psylli cured the bite of serpents; and it is related of Cato, that his abhorrence of the Greek surgeons was such, that he directed Psylli to follow the Roman armies.

Water affords a beautiful illustration of that indestructibility with which the Creator invested matter for the preservation of the world he formed from elementary masses, and appears to have existed unchangeable from the commencement of the universe. Its constituent parts are not

broken into by any atmospheric revolution; they continue the same, whether in the solid ice, the fluid state of a liquid, or the gaseous form of a vapour. Its powers are undiminished, whether in the wave or the steam; the most effective agent in the hands of man to promote that welfare and happiness which his own errors deprive him of, frequently bringing on those calamities that his perversity attributes to the will of the Omnipotent. Water is the same in the atmosphere as on the earth, and falls in the very same nature as it ascends; electricity has no other influence upon it than that of hastening its precipitation. Chemical agents, however powerful, can only decompose its elementary principles upon the most limited scale. The heterogeneous substances with which water may occasionally be alloyed must be considered as purely accidental.

The homogeneous characters of this fluid admit of no alteration, and, like atmospheric air, are still obtained as pure most probably as when they first emerged from chaotic matter. The same principles are found in the clouds, the fogs, the dews, the rain, the hail, and the snow. For the preservation of the world it was indispensable that water should be endowed with the property of ever retaining its fluid form,
