The whippet sequence shows double suspension, which
means all four feet off the ground both in a collected
or flexed phase, and in full extension. Horses have a
single suspension gallop (flexed phase), although I
think that some Thoroughbreds (Secretariat IIRC) have
been found to have the extended phase as well.
I suppose if the page had had the Muybridge human locomotion series
it would have been deemed unsuitable for posting without a warning.
And I wonder why he never did one of cats?
