Near the road I saw the under-jaw of a horse, having six fore-teeth, much worn and blunted; two canine teeth; and at a distance from the latter twelve grinders, six on each side. If I knew how many teeth, and of what peculiar form, as well as how many udders and where situated, each animal has, I should perhaps be able to contrive a most natural methodical arrangement of quadrupeds. [This observation seems to record the first idea of the Linnæan system of the order of the mammalia.]
On June 18 the people brought me a peasant's child, supposed to have cataract. I concluded that it was not cataract; but noticing that the eyeballs rolled upwards when the child was spoken to, I asked the mother whether, when she was with child, she had seen anybody turn their eyes in that manner. She replied that she had attended her mother, or mother-in-law, who was supposed to be dying, whose eyes rolled in a similar fashion. This was the cause of the infant's misfortune.
At Lulea I was informed of a disease of cattle so pestilential that though the animals were flayed even before they were cold, whenever their blood had come in contact with the human body it had caused gangrenous spots and sores. Some persons had both their hands swelled, and one his face, in consequence of the blood coming upon it. Many people had lost their lives by the disease, insomuch that nobody would now venture to flay any more of the cattle, but contrived to bury them whole.
On June 30 I arrived at Jockmock, where the curate and schoolmaster tormented me with their consummate and most incorrigible ignorance. I could not but wonder that so much pride and ambition, such scandalous want of information, with such incorrigible stupidity, could exist in persons of their profession, who are commonly expected to be men of knowledge. No man will deny the propriety of such people as these being placed as far as possible from civilised society.
The learned curate began his conversation by remarking how the clouds as they strike the mountains carry away stones, trees, and cattle. I ventured to suggest that such accidents were rather to be attributed to the force of the wind, since the clouds could not of themselves carry away anything. He laughed at me, saying surely I had never seen any clouds. For my part it seemed to me that he could never have been anywhere but in the clouds. I explained that when the weather is foggy I walk in clouds, and that when the cloud is condensed it rains. At all such reasoning, being above his comprehension, he only laughed with a sardonic smile. Still less was he satisfied with my explanation how watery bubbles may be lifted into the air. He insisted that the clouds were solid bodies, reinforced his assertion with a text of Scripture, silenced me by authority, and laughed at my ignorance.
