(17) It was found that the bipeds developed typical characteristics of the upright posture: complete erectness of the torso and legs and noticeable enhancement of lumbar lordosis.
(18) It was, and is, the capital of work, the cast-iron, steel-and-glass leveller of men; the city where dust from the "subway" system elevated above the streets on iron stilts showers down on the bipeds beneath regardless of status.

(20) Results of this study show reduction in litter size in the amputated groups, with greater reduction of offspring among the biped group, than in the asymmetric group.
