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.
