Carl Linnaeus, The Lapland Journey, translated by Peter Graves (Edinburgh: Lockharton Press, 1995), p. 142.
The Mountains [2], 19/07/1732, ¶737:
- In Norway a good and healthy cow costs 3 riksdaler.
- A reindeer cow costs 1 riksdaler.
- An ox costs 12 to 18 silver daler.
- A reindeer ox costs 12 to 18 copper daler.
Therefore, 3 reindeer are equal to 1 head of cattle.
