As we have said elsewhere, in speaking of the Tartar-Mongols, the Lamas introduce many superstitious practices into medicine. Yet, notwithstanding all this quackery, there is no doubt that they possess an infinite number of very valuable recipes, the result of long experience. It were, perhaps, rash to imagine that medical science has nothing to learn from the Tartar, Thibetian, and Chinese physicians, on the pretext that they are not acquainted with the structure and mechanism of the human body. They may, nevertheless, be in possession of very important secrets, which science alone, no doubt, is capable of explaining, but which, very possibly, science itself may never discover. Without being scientific, a man may very well light upon extremely scientific results. In China, Tartary, and Thibet, everybody can make gunpowder; yet it may be safely propounded that not one of these powder-makers can explain scientifically this chemical operation; each man has a good receipt for making the powder, and he makes it. Towards September, we received the joyful intelligence that the Thibetian embassy had arrived at Tang-Keou-Eul, where it was to remain for several days, in order to lay in a stock of provisions, and arrange its order of march. Thus, then, after long and annoying delay, we were about to proceed to the capital of Thibet. We made, without loss of time, all our necessary preparations. First we had to pay a visit to Kounboum, in order to purchase provisions for four months, since, on the whole route, there was not the least hope of finding any thing to buy that we might want. Upon a careful calculation, we found that we should require five bricks of tea, two sheep’s paunches of butter, two sacks of flour, and eight sacks of tsamba. Tsamba is the name given here to barley-meal, the insipid article which constitutes the ordinary food of the Thibetians. They take a tea-cup half filled with boiling tea; to this they add some pinches of tsamba, and then mix these materials together with the finger, into a sort of wretched paste, neither cooked nor uncooked, hot nor cold, which is then swallowed, and is considered breakfast, dinner, or supper, as the case may be. If you desire to cross the desert to Lha-Ssa, you must perforce resign yourself to tsamba; ’tis to no avail the French traveller sighs for his accustomed knife and fork, and his accustomed knife and fork dishes: he must do without them. Persons, full of experience and philanthropy, counselled us to lay in a good store of garlic, and every day to chew several cloves of it, unless we wished to be killed on our way by the deleterious vapours, that emanated from certain elevated mountains. We did not discuss the merits of this hygeianic advice, but adopted it with absolute confidingness.
