The Ostiaks have likewise other idols, whose origin and worship are as little deserving our notice as their worshippers. There were some converts to Christianity made amongst them in the year 1712; but these, like the lowest of our peasants, are Christians without knowing what they profess. Several writers pretend that these people were natives of Great Permia, but as Great Permia is in a manner a desert, how comes it that its inhabitants should settle themselves at such a distance, and so inconveniently? This is a difficulty not worth clearing up. Every nation which has not cultivated the polite arts, deserves to remain in obscurity. In the country of the Ostiaks in particular, and amongst their neighbours the Burates and Jakutians, they often discover a kind of ivory under ground, the nature of which is as yet unknown. Some take it to be a sort of fossil, and others the tooth of a species of elephants, the breed of which have been destroyed: but where is the country that does not afford some natural productions, which at once astonish and confound philosophy. Several mountains in this country abound with the amianthes or asbestos, a kind of incombustible flax, of which a sort of cloth and paper is sometimes made. To the south of the Ostiaks are the Burates, another people, who have not yet been made Christians. Eastward there are several hordes, whom the Russians have not as yet entirely subdued. None of these people have the least knowledge of the calendar: they reckon their time by snows, and not by the apparent motion of the sun: as it snows regularly, and for a long time every winter, they say, 'I am so many snows old,' just as we say, I am so many years. And here I must relate the accounts given by the Swedish officer Strahlemberg, who was taken prisoner in the battle of Pultowa, and lived fifteen years in Siberia, and made the entire tour of that country. He says, that there are still some remains of an ancient people, whose skin is spotted or variegated with different colours, and that he himself had seen some of them, and the fact has been confirmed to me by Russians born at Tobolsky. The variety of the human species seems to be greatly diminished, as we find very few of these extraordinary people, and they have probably been exterminated by some other race: for instance there are very few Albinos, or White Moors; one of them was presented to the academy of sciences at Paris, which I saw. It is the same with respect to several other species of animals which are rare. As to the Borandians, of whom mention is made so frequently in the learned history of the king's garden, my memoirs say, that this race of people is entirely unknown to the Russians.
