Figures

Two of the three red-chalk drawings are preserved at the Royal Society. The scans on the sidebars came from the 1708 third edition of Arcana Naturae Microscopiorum.

In the text, Leeuwenhoek noted that he had them drawn by someone.

I had a drawing made of a small piece of oak, as the same, on its end, presented itself to the naked eye after being planed smooth; as fig.: 1.

In order to show the difference in the oak brought hither from the Baltic Countries, from Koenigsberg and Riga, I have had a piece of that wood drawn. Fig: 2.

Now in order to demonstrate the structure of Pine, I have thought fit to have a drawing made of a very small piece of Wood.

He discussed Fig. 1 at the beginning of the letter and again at the end. In all of the Dutch and Latin editions, Fig. 1 was reprinted within sight of the second discussion.
