Travels in China, Sir John Barrow [phonics readers txt] 📗

It may be considered as superfluous, after what has been said, to observe, that no branch of natural philosophy is made a study, or a pursuit in China. The practical application of some of the most obvious effects produced by natural causes could not escape the observation of a people who had, at an early period, attained so high a degree of civilization, but, satisfied with the practical part, they pushed their enquiries no farther. Of pneumatics, hydrostatics, electricity, and magnetism, they may be said to have little or no knowledge; and their optics extend not beyond the making of convex and concave lenses of rock crystal to assist the sight in magnifying, or throwing more rays upon, small objects and, by collecting to a focus the rays of the sun, to set fire to combustible substances. These lenses are cut with a saw and afterwards polished, the powder of crystal being used in both operations. To polish diamonds they make use of the powder of adamantine spar, or the corundum stone. In cutting different kinds of stone into groups of figures, houses, mountains, and sometimes into whole landscapes, they discover more of persevering labour, of a determination to subdue difficulties, which were not worth the subduing, than real ingenuity. Among the many remarkable instances of this kind of labour, there is one in the possession of the Right Honourable Charles Greville, that deserves to be noticed. It is a group of well formed, excavated, and highly ornamented bottles, covered with foliage and figures, raised in the manner of the antique Cameos, with moveable ring-handles, standing on a base or pedestal, the whole cut out of one solid block of clear rock crystal. Yet this laborious trifle was probably sold for a few dollars in China. It was bought in London for about thirty pounds, where it could not have been made for many times that sum, if, indeed, it could have been made at all. All their spectacles that I have seen were crystal set in horn, tortoise-shell, or ivory. The single microscope is in common use, but they have never hit upon the effect of approximating objects by combining two or more lenses, a discovery indeed to which in Europe we are more indebted to chance than to the result of scientific enquiry. I observed at Yuen-min-yuen a rude kind of magic lantern, and a camera obscura, neither of which, although evidently of Chinese workmanship, appeared to wear the marks of a national invention. I should rather conclude, that they were part of those striking and curious experiments which the early Jesuits displayed at court, in order to astonish the Emperor with their profound skill, and raise their reputation as men of learning. Of the ombres Chinoises they may, perhaps, claim the invention, and in pyrotechny their ingenuity may be reckoned much superior to any thing which has hitherto been exhibited in that art in Europe.

A convex lens is among the usual appendages to the tobacco pipe. With these they are in the daily habit of lighting their pipes. Hence the great burning lens made by Mr. Parker of Fleet-Street, and carried out among the presents for the Emperor, was an object that excited no admiration in the minds of the Chinese. The difficulty of making a lens of such magnitude perfect, or free from flaw, and its extraordinary powers could not be understood, and consequently not appreciated by them: and although in the short space of four seconds it completely melted down one of their base copper coins, when the sun was more than forty degrees beyond the meridian, it made no impression of surprize on their uninformed minds. The only enquiry they made about it was, whether the substance was crystal; but being informed it was glass, they turned away with a sort of disdain, as if they would say, Is a lump of glass a proper present to offer to our great Whang-tee? The prime minister, Ho-tchung-tang, in order to convince us how very familiar articles of such a nature were to him, lighted his pipe very composedly at the focus, but had a narrow escape from singeing his sattin sleeve, which would certainly have happened had I not given him a sudden push. He seemed, however, to be insensible of his danger, and walked off without the least concern.

Indeed, in selecting the many valuable presents relating to science, their knowledge and learning had been greatly overrated. They had little esteem for what they could not comprehend, and specimens of art served only to excite their jealousy, and to wound their pride. Whenever a future embassy shall be sent to Pekin, I should recommend articles of gold, silver, and steel, children's toys and trinkets, and perhaps a few specimens of Derbyshire spar, with the finest broad-cloth and kerseymeres, in preference to all others; for in their present state, they are totally incapable of appreciating any thing great or excellent in the arts and sciences.

To alleviate the afflictions of mankind, and to assuage the pains which the human frame is liable to suffer, must have been among the earliest studies of civilized society; and accordingly, in the history of ancient kingdoms, we find the practitioners of the healing art regarded even to adoration. Chiron, the preceptor of Achilles, and the master of Æsculapius, was transferred to the heavens, where he still shines under the name of Sagittarius. Among these nations, indeed, which we call savage, there is usually shewn a more than ordinary respect for such of their countrymen as are most skilled in removing obstructions, allaying tumours, healing bruises, and, generally speaking, who can apply relief to misery. But the Chinese, who seem to differ in their opinions from all the rest of mankind, whether civilized or savage, pay little respect to the therapeutick art. They have established no public schools for the study of medicine, nor does the pursuit of it lead to honours, rank, or fortune. Such as take up the profession are generally of an inferior class; and the eunuchs about the palace are considered among their best physicians. According to their own account, the books on medicine escaped the fire, by which they pretend the works of learning were consumed, in the reign of Shee-whang-tee, two hundred years before the Christian era; and yet the best of their medical books of the present day are little better than mere herbals, specifying the names and enumerating the qualities of certain plants. The knowledge of these plants and of their supposed virtues goes a great way towards constituting a physician. Those most commonly employed are Gin-sing, rhubarb, and China-root. A few preparations are also found in their pharmacopœia from the animal and the mineral kingdoms. In the former they employ snakes, beetles, centipedes, and the aureliæ of the silk worm and other insects; the meloe and the bee are used for blisters. In the latter, saltpetre, sulphur, native cinnabar, and a few other articles are occasionally prescribed. Opium is taken as a medicine, but more generally as a cordial to exhilarate the spirits. Though the importation of this drug is strictly prohibited, yet, as I have before observed, vast quantities are annually smuggled into the country from Bengal and from Europe, through the connivance of the custom-house officers.

The physiology of the human body, or the doctrine which explains the constitution of man, is neither understood, nor considered as necessary to be known; and their skill in pathology, or in the causes and effects of diseases, is extremely limited, very often absurd, and generally erroneous. The seat of most diseases are, in fact, supposed to be discoverable by feeling the pulse, agreeably to a system built upon principles the most wild and extravagant. Having no knowledge whatsoever of the circulation of the blood, notwithstanding the Jesuits have made no scruple in asserting it was well known to them long before Europeans had any idea of it, they imagine, that every particular part of the human body has a particular pulse assigned to it, and that these have all a corresponding and sympathetic pulse in the arm; thus, they suppose one pulse to be situated in the heart, another in the lungs, a third in the kidneys, and so forth; and the skill of the doctor consists in discovering the prevailing pulse in the body, by its sympathetic pulsations in the arm; and the mummery made use of on such occasions is highly ludicrous.

By eating too freely of unripe fruit at Chu-san I had a violent attack of cholera morbus, and on application being made to the governor for a little opium and rhubarb, he immediately dispatched to me one of his physicians. With a countenance as grave and a solemnity as settled, as ever was exhibited in a consultation over a doubtful case in London or Edinburgh, he fixed his eyes upon the ceiling, while he held my hand, beginning at the wrist, and proceeding towards the bending of the elbow, pressing sometimes hard with one finger, and then light with another, as if he was running over the keys of a harpsicord. This performance continued about ten minutes in solemn silence, after which he let go my hand and pronounced my complaint to have arisen from eating something that had disagreed with the stomach. I shall not take upon me to decide whether this conclusion was drawn from his skill in the pulse, or from a conjecture of the nature of the complaint from the medicines that had been demanded, and which met with his entire approbation, or from a knowledge of the fact.

Le Compte, who had less reason to be cautious, from his having left the country, than other missionaries who are doomed to remain there for life, positively says, that the physicians always endeavour to make themselves secretly acquainted with the case of the patient, before they pronounce upon it, as their reputation depends more on their assigning the true cause of the disorder than on the cure. He then proceeds to tell a story of a friend of his who, being troubled with a swelling, sent for a Chinese physician. This gentleman told him very gravely, that it was occasioned by a small worm which, unless extracted by his skill, would ultimately produce gangrene and certain death. Accordingly one day
