After Henry Oldenburg died, the Royal Society did not have the resources to replace him as owner, publisher, and editor of Philosophical Transactions. Hooke took it upon himself to publish a dozen letters/articles written by himself and other scholars who had previously published in Philosophical Transactions, including Robert Boyle and Edmond Halley.

Hooke published most of two of Leeuwenhoek's letters.

  • Letter 21 of October 5, 1677, addressed to Henry Oldenburg before Leeuwenhoek knew that he had died a month earlier, in September.
  • Letter 23 of January 14, 1678, addressed to himself.

Neither of these letters was accompanied by figures.


This publication contains the only contemporary printed versions of two Leeuwenhoek letters. They are listed separately among the primary printed sources. The rest of the book contains articles by Hooke relevant in their own right and Hooke's comments on Leeuwenhoek's letters, so the book is listed among the secondary printed literature.
