The relation of fauns, segipans,and goats is discussed further inchapter iv. in connection with someother structural peculiarities theyshare in common with goats. Atrophy of parts when disusedin consequence of injury scarcelycalls for comment (though verymany interesting specimens might claw from a Two-toedbe described) because the effectsof disuse when thus induced are not inherited. As a general rule, the statement that parts whendisused become reduced in size holds good, but in con-nection with dermal organs such as nails, horns, andclaws, it is well to point out that disuse leads to en-largement. In the preceding chapter specimens were. Fig. 29.—An elongated 58 EVOLUTION AND DISEASE. described to demonstrate the increase in the size ofdermal organs when disuse and irritation from dirt, &c,were combined. A few specimens will now be con-sidered in which disuse alone seems responsible for the
