What time interval did Muybridge state for his walking plate, and what does it imply in modern frame terms?
Muybridge's 1887 prospectus describes plate 14: a model walking one stride, twelve phases about 0.120 s apart by chronograph, whole movement about one and a half seconds. Intervals in the series ranged from 1/60 s to several seconds and were timed with a 100 Hz tuning fork. Twelve phases at 0.120 s span 1.32 s (11 intervals), a little shorter than his stated 'about one and a half seconds', so the figure is approximate; a stride of about 1.3-1.5 s is slower than the 1.09-1.15 s in modern samples. Per-plate interval columns in the catalogue table were too garbled in the OCR to read.

Curator qualifications: Excerpted evidence located; Muybridge stride ~1.3-1.5 s vs modern 1.09-1.15 s (model/speed unknown) kept.
Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.
