Progression of Animals (or On the Gait of Animals; Latin: De incessu animalium) is a text by Aristotle on the details of gait and movement in various species of animals.
Aristotle's approach to the subject is to ask "why some animals are footless, others bipeds, others quadrupeds, others polypods, and why all have an even number of feet, if they have feet at all; why in fine the points on which progression depends are even in number."
It's a good example of the way he brought teleological presumptions to empirical studies.

“Measured by any standard known to science—by horse-power, calories, volts, mass in any shape,—the tension and vibration and volume and so-called progression of society were full a thousand times greater in 1900 than in 1800;Mthe force had doubled ten times over, and the speed, when measured by electrical standards as in telegraphy, approached infinity, and had annihilated both space and time. No law of material movement applied to it.”

“He will deliver you from six troubles; in seven no harm shall touch you. In famine he will redeem you from death, and in war from the power of the sword. You shall be hidden from the scourge of the tongue, and shall not fear destruction when it comes. At destruction and famine you shall laugh, and shall not fear the wild animals of the earth. For you shall be in league with the stones of the field, and the wild animals shall be at peace with you.”
—Bible: Hebrew, Job 5:19-23.
