• A few moments later, a rifle flash and a bang, and then a fusillade brought Jack’s heart into his throat. The pickup car jetted toward it; by the time it reached the spot, the shooting had stopped, and a crowd was gathering around something white on the ground.

• Professor Cope, the American paleontologist, was a strong believer in the effect of activity, both upon the individual and upon his descendants.

Wikipedia:

Ungulates are several groups of mammals, most of which use the tips of their toes, usually hoofed, to sustain their whole body weight while moving. They make up several orders of mammals, of which six to eight survive. There is some dispute as to whether Ungulata is a cladistic (evolution-based) group, or merely a phenetic group or folk taxon (similar, but not necessarily related), because not all ungulates appear as closely related as once believed.
