Letter 29 of January 12, 1680 Figure 1 | Levende Dierkens

Circumference of an imaginary oak, ash etc. tree, which has 18 rings and consequently is 18 years old.

De circumferentie van een geïmagineerden eijcken-, essen-, etc. boom, de welcke 18 kringen heeft en daerom 18 jaren out is.


This figure is unnumbered at the end of the manuscript, after Leeuwenhoek's signature. In Levende Dierkens, the text was moved to the second page (p. 18) and the figure is Fig. 1. For the printed versions, all of the figures were renumbered.
