LEEUWENHOEK AND HIS “LITTLE ANIMALS” 
microscopes were purchased by Hollanders,' and it is 
therefore surprising that one nowadays so seldom meets 
with any surviving specimens of Leeuwenhoek’s instru- 
ments in this country. 
Elsewhere Harting has published a list of the objects 
which Leeuwenhoek left fixed before his magnifying-glasses— 
as mentioned in the sale-catalogue. Though they include 
—like Folkes’s list—no protozoological or bacteriological 
items, they seem sufficiently interesting to quote. According 
to Harting, they were as follows: ”
