Key to the Table
The first three columns in the table above note the tenure of the editors of the Royal Society's journal, Philosophical Transactions, its volume, and its official year of publication.
The next three columns show the number of letters written and eventually published, according to Cole, the number published in that volume of Philosophical Transactions, and the number published either by Hooke in English or by Leeuwenhoek himself in Dutch.

During this time, at his own expense, van Leeuwenhoek began to publish the complete versions of his letters in the original Dutch. As shown on the table, left, he started with four pamphlets whose titles all began Ondervindingen en Beschouwingen / Experiences and Considerations, all printed by Daniel van Gaesbeeck in Leiden in 1684. The first contained the letters of June 14 and November 12, 1680. Neither was ever published in Philosophical Transactions, but the second had been published in Hooke's Philosophical Collections.
The three other pamphlets' titles all began Ontledingen en Ontdekkingen / Analyses and Discoveries. They were printed by Cornelis Boutesteyn in 1685. Both Boutesteyn and van Gaesbeeck were in Leiden, just 12 miles up the Vliet canal from Delft, which did not have the university and thus large publishing industry that Leiden did.
In 1685, van Leeuwenhoek stepped up his self-publication program. He began publishing larger pamphlets and finally collected 25 letters from nine pamphlets to become the first of what turned out to be four self-published volumes of his letters. He retained the pagination from the original pamphlets, so four different letters begin on "page 1".
These 25 include all 11 from this time period.
Bibliographic note: Dobell includes the eight letters (#53-60) written in 1687 in the second self-published volume. Cole includes these eight letters in the first self-published volume.
