Kaempfer’s suggestions were ingenious, though his theory was erroneous. But, although he rather impeded than assisted in the correct identification of the object of discussion, he, at least, helped to discredit the myth, which he declared to be one of those “received with favour by the superstitious, and which when once they have found a writer to describe them, however incorrectly, please the many, obtain numerous adherents, and become respectable by age.”

Fig. 4.—Rhizome of a fern, shaped by the Chinese to represent a tan-coloured dog, and laid before the Royal Society by Sir Hans Sloane as a specimen of the “Barometz,” or “Tartarian Lamb.”

From the ‘Philosophical Transactions,’ vol. xx. p. 861.

An important chapter in the history of this curious fiction was reached when, in 1698, Sir Hans Sloane[15] laid before the Royal Society an object which has ever since been generally regarded as a specimen of the strange natural production about which so much mystery had existed, so many outrageous stories had been told, and on which so much learned discussion had been expended. His description of it is printed in the Society’s Transactions, and is as follows:—

[15] Philosophical Transactions, vol. xx. p. 861; and Lowthorp’s Abridgment of the Phil. Trans. vol. ii. p. 649.

“The figure ([fig. 4]) represents what is commonly, but falsely, in India, called ‘the Tartarian Lamb,’ sent down from thence by Mr. Buckley.[16] This was more than a foot long, as big as one’s wrist, having seven protuberances, and towards the end some foot-stalks about three or four inches long, exactly like the foot-stalks of ferns, both without and within. Most part of this was covered with a down of a dark yellowish snuff colour, some of it a quarter of an inch long. This down is commonly used for spitting of blood, about six grains going to a dose, and three doses pretended to cure such a hæmorrhage. In Jamaica are many scandent and tree ferns which grow to the bigness of trees, and have such a kind of lanugo on them, and some of the capillaries have something like it. It seemed to be shaped by art to imitate a lamb, the roots or climbing parts being made to resemble the body, and the extant foot-stalks the legs. This down is taken notice of by Dr. Merret at the latter end of Dr. Grew’s Mus. Soc. Reg. by the name of ‘Poco Sempie,’ a ‘golden moss,’ and is there said to be a cordial. I have been assured by Mr. Brown, who has made very good observations in the East Indies, that he has been told by those who lived in China that this down or hair is used by them for the stopping of blood in fresh wounds, as cob-webs are with us, and that they have it in so great esteem that few houses are without it; but on trials I have made of it, though I may believe it innocent, yet I am sure it is not infallible.”

[16] This specimen evidently came from China; for I find a record that at the date of Sir Hans Sloane’s paper “Mr. Buckley, Chief Surgeon at Fort St. George, in the East Indies, presented to the Royal Society a cabinet containing Chinese surgical and other instruments and simples.”

Sir Hans Sloane had, it is true, clearly perceived the nature of the specimen sent to the Royal Society by Mr. Buckley, and had correctly identified it as a portion of one of the arborescent ferns; but on the question whether he had discovered the right interpretation of the puzzling enigma I shall have more to say presently. The object figured seems to have been regarded by many of his contemporaries as so insufficient to meet the requirements of the oft-told story of the plant-animal, and so unsatisfactory an explanation of it, that every one who subsequently had an opportunity of visiting Tartary still felt it to be his duty to make enquiries concerning the famous prodigy of that country.
