Here’s a book I haven’t read in some sixty years: Antony van Leeuwenhoek and His ‘Little Animals’ by Clifford Dobell, published in 1932 by Harcourt, Brace and Co. Reading it was the product of childhood obsessions colliding: biographies and microscopes. In some volume of potted lives I learned of Van Leeuwenhoek’s pioneering contributions to microscopy and microbiology. I remember reading that he was likely to have been the first person in history to have examined his own blood using a microscope. I was given a microscope for my twelfth birthday and looked at almost anything under its lenses: a butterfly wing, dirt from under my fingernails, creek water, cottage cheese and, yes, my own blood.
I remember Dobell’s book
being the kind I like, filled with interesting tidbits of information, the sort
of thing some will describe as “trivia.” For instance, Van Leeuwenhoek was the
first to suggest that motility – OED: “the power of active movement” -- is
indicative of life. The microscopic “animalcules” he observed could move, therefore
they were living things. Dobell writes: “Leeuwenhoek’s observations on the
free-living Protozoa probably began with his discovery of certain ‘very little
animalcules’ which he saw in fresh water in the year 1674.” Then he quotes from
a letter the Dutchman sent from Delft to the Royal Society in London. There’s a
childlike excitement in Van Leeuwenhoek’s observations that I find charming. I’ll
quote some at length:
“[A]mong these there were,
besides, very many little animalcules, whereof some were roundish, while
others, a bit bigger, consisted of an oval. On these last I saw two little legs
near the head, and two little fins at the hindmost end of the body. Others were
somewhat longer than an oval, and these were very slow a-moving, and few in
number. These animalcules had divers colours, some being whitish and
transparent; others with green and very glittering little scales; others again
were green in the middle, and before and behind white; others yet were ashen
grey. And the motion of most of these animalcules in the water was so swift,
and so various, upwards, downwards, and round about, that ’twas wonderful to
see: and I judge that some of these little creatures were above a thousand times
smaller than the smallest ones I, have ever yet seen, upon the rind of cheese,
in wheaten flour, mould, and the like.”
I see Dobell dedicated his
book to two writers I would come to read years later: D’Arcy Wentworth Thompson,
author of On Growth and Form (1917), discovered thanks to Hugh Kenner,
and Paul de Kruif, author of Microbe Hunters (1926). In No End in
Strangeness: New and Selected Poems (Cormorant Books, 2011), the Canadian
poet Bruce Taylor includes a ten-page poem, “Little Animals,” a lyric with the
narrative drive of a good short story and the free-wheeling discursiveness of
an essay or one of those marvelous prose curiosities from Van Leeuwenhoek’s seventeenth
century – Religio Medici or The Anatomy of Melancholy. Looking
through his microscope at the roiling ocean of life in a drop of water from the
pond, Taylor writes:
“And there is no end to
them,
no end in numbers,
and no end in strangeness,
no end to their appetites,
and all of it
exactly as van Leeuwenhoek
described it to us all
those years ago,
when he, being the first
to look
became the first to see
that what the wise men
said was wrong,
what gnaws at our lapsed
and sinful
world is not death at all,
the old machinework
mannequin
swinging his scythe, he is
not there.”
Taylor’s poem is, among
other things, a hymn to reading. He gives “Little Animals” an epigraph from
Chaucer’s “Legend of Good Women”: “On bokes for to rede I me delyt.”
Van Leeuwenhoek was born in 1632 (the same year as another Dutch lens grinder, Baruch Spinoza) and died on this date, August 26, in 1723.
