Summary:
Examples of animals that dwell in dark places, some of which are blind, some not. Asks: where causes are the same, why is not the effect? Does not think disuse is the answer, but arrested development.
Comments also on the absence of a ligament in four mammals and asks how natural selection accounts for this.
