Dedication from Leeuwenhoek to Frederik Adriaan Baron van Reede
After a page listing the titles and responsibilities of Frederik Adriaan, Leeuwenhoek wrote a dedication (opdract) to his friend. He recalled frequent visits to the Baron's estate outside of Utrecht and elsewhere, perhaps Den Haag, where he also lived. The visits included Leeuwenhoek's daughter (my als ook de mijne) and perhaps his second wife, though she had been dead for two years when Leeuwenhoek wrote this dedication. These visits may well have included the Baron's wife, Maria Duyst, who grew up across the gracht from Leeuwenhoek and was only five years younger than his daughter Maria.
Poem by P. Rabus
Aan den Heere Antoni van Leeuwenhoek Op het Vijfde Vervolg Zijner Ontdekking-Brieven
To Mr. Antoni van Leeuwenhoekon the Fifth Continuation of his Discovery-Letters
Leeuwenhoek wrote these 13 letters in the 15 months between late 1694 and the end of 1695. Only the first of these letters was addressed to an officer of the Royal Society, Richard Waller. He was the only one of the five addresses whom Leeuwenhoek did not know personally. However, around this time, he sent Waller a copy of the 1687 edition of Anatomia Seu interiora Rerum with the misspellings on the title page.
The next letter was addressed to Pieter Rabus, who also wrote two parts of the front matter. Four letters were addressed to Leeuwenhoek's old friend from the Stadhuis, Anthonie Heinsius. Five were addressed to Frederik Adriaan. The final two, in late 1695, were addressed to Johann Wilhelm von Pfalz-Neuburg, who had visited Leeuwenhoek in Delft the previous August.
None of these letters was published in Philosophical Transactions.
There were 48 figures in 7 of the 13 letters.
The volume concluded with a 10-page index (blad-wyser, literally: page pointer).
