ELUCIDATIONS AND ANNOTATIONS 
HE following supplementary notes—dealing with very 
various subjects—are collected together here simply 
because they are too long to print as footnotes to the 
foregoing text. They contain much that is important for the 
student of Leeuwenhoek and his writings, but the reader will 
please bear in mind that they are notes and explanations 
only—not full dissertations on the subjects treated. My 
information has been gathered from many sources during 
many years, but is still far from complete: and I offer it to fellow- 
students merely in the hope that it may help them in their 
own studies. On some matters I could, indeed, say much in 
addition: but as Father Antony himself would say, “I will 
spare you more, for ’twould else take all too long a-writing.”’ 
(i) LEEUWENHOEK’S NAME 
As the curious name “ Leeuwenhoek ”’ has, seemingly, at 
all times been a stumbling-block to foreigners (and has even 
puzzled Dutch scholars), the following annotations may not 
be amiss. 
LEEUWENHOEK, as a surname, appeared until quite recently 
to be extinct. I have been unable to find anybody bearing it 
since the middle of the X VIII Century: but my researches in 
this connexion were only superficial, and Mr Bouricius has 
delved deeper and has deservedly been more successful. He 
has discovered’ that there are still Leeuwenhoeks living in 
Holland—“ between Oudewater and Gouda.” ‘They are, so 
‘ Bouricius believes,’ descendants from Antony’s uncle * Huych 
[=Hugh]|—his father’s only brother. (See the Family Tree, 
’ Cf. Schierbeek (1929, 1930). 
2 Mr Bouricius’s researches—though unpublished—seem to have been 
very thorough: for Schierbeek (1930), who has seen his notes, says that 
“the genealogy is completely ascertained’’ of these present-day Leeuwenhoeks. 
* “ Oudoom”’ [ = great-uncle] according to Schierbeek (1930).
