... ingenious as Slimak was, he never dared to do anything fresh unless driven to it. He understood his farm work thoroughly, he could even mend the thrashing-machine at the manor-house, and he kept everything in his head, beginning with the rotation of crops on his land.

... the homologous limb of its purely aquatic predecessor, there is to be noticed the disappearance of one of the six rows of small bones, a confluence of some of the remainder in the other five rows, a duplication of the arm-bone into a radius and ulna, in order to admit of jointed rotation of the hand, and a general disposition of the small bones below these arm-bones, which clearly foreshadows the joint of the wrist. Indeed, in this fore-foot of Chelydra, a child could trace all the principal homologies of the mammalian counterpart, growing, ...
