Ă…ngermanland, 23/05/1732, ¶201:

The farmers filch its eggs. They say that it does not lay more than one egg at a time and, if that one is taken, it lays again and again. It seems to me rather strange – indeed, quite impossible – that the annual increase of the species is not more than one and one alone. Some people said that it lays 2 eggs. What is certain, however, is that its eggs are very large in relation to its body. I saw some fragments of one and I think I can be fairly sure that it is ‘Anas Arctica’ [Razorbill].
