Magnification here is ten million times, and the structure of the salt crystal can
be shown. Distances between the successive layers of sodium (1) and chlorine
(2) atoms in the lattice of the crystal are known, though its height would be 5
kilometers on this scale. To the left oxygen (3) and nitrogen (4) molecules are
moving about as air at average distances indicated. Nitrogen molecules are
more than 3 times as numerous as oxygen. In the inset a schematic sketch is
given of just one strand of the flagellum, and even so only the hydrogen atoms
on the near side are indicated. Otherwise the representation would become unintelligible,
as the other atoms behind them are not placed in regular rows as
they are in the salt crystal. Total width of the protein molecule including the
amino acids which are bound to the strand is indicated (5).
