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.[20]
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:
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, and in this respect become subject to a law different from that of other bodies, which change from fluid to solid. This is a deviation from a general decree of Nature. Were it not for this wise provision of the Creator, the world would shortly have been converted into a frozen chaos. All bodies contract their dimensions, and acquire a greater specific gravity by cooling; but water is excepted from this law, and becomes of less specific gravity, whether it be heated, or cooled below 42° 5′. Were it not for this exemption, it would have become specifically heavier by the loss of its caloric, and the waters that float on the surface of rivers would have sunk as it froze, until the beds of rivers would have been filled up with immense masses of ice. From the observations of Perron, there is reason to believe that the mountainous accumulations of ice that have hitherto arrested the progress of polar navigators have been detached from the depths of the ocean to float upon its surface. This circumstance would account for the difference of temperature of the sea according to its depth. The experiments of Perron, made with an instrument of his own invention, which he called the thermobarometer, gave the following results:
1st, The temperature of the sea upon its surface, and at a distance from shore, is at the meridian, lower than that of the atmosphere in the shade; much more elevated at midnight, but in a state of equilibrium morning and evening.
2nd, The temperature rises as we approach continents or extensive islands.
3rd, At a distance from land, the temperature of the deep parts of the sea is lower than that of the surface, and the cold increases with the depth. It is this circumstance which led this ingenious philosopher to conclude that even under the equator the bottom of the sea is eternally frozen.
Humboldt is of a contrary opinion, and maintains that the temperature is from two to three degrees lower in shallow water; and he therefore is of opinion that the thermometer might prove of material use to navigators. He attributes this diminution of temperature to the admixture of the lower bodies of water with that of the surface. Who is to decide between these two ingenious experimentalists? “Experientia fallax, judicium difficile.” The curious reader may consult in this investigation the tables of Forster in Cook’s second voyage, those of Lord Mulgrave when Captain Phipps, and various other navigators.
