Leeuwenhoek wrote this letter about the origin of life to Lambert van Velthuysen, a supporter from Utrecht. It was not published during Leeuwenhoek's lifetime. It was one of a dozen letters that P. Haaxman contributed to the 1875 exhibition. Harting summarized this letter in the exhibition's Gedenkboek.
