Ixx : CHARLES OTIS WHITMAN 
acters have been evolved by gradual modification. The continu- 
ity in the evolution of some of these characters can be experi- 
mentally demonstrated. The little Diamond Dove (Geopelia 
cuneata) of Australia, owes its small white spots (two in each 
feather) to these bars. The transitional stages connecting the 
spots with the bars are not wholly given in passing from the juvenal 
to the adult plumage. But if we pluck a few of the juvenal 
feathers at suitable intervals, their places will be filled by new 
feathers of different ages, and in this way we may get the stages 
intermediate between the bars of the young and the spots of the adult. 
Thus we see that the adult pattern, which normally appears to 
come in as a striking mutation, by a single gump, is only an end- 
stage in a continuous process of differentiation. So it is every- 
where. Suppression of stages in ontogeny looks like saltations; 
but whenever we can get at the history of the character, we find the 
continuity comes to light.” 
PERSONAL CHARACTERISTICS 
We have described principally the outward events of a life 
that was not lacking in incident. Many traits of character shine 
through these events, but the history of his inner life is far from 
being comprised in such a sketch, and there is no one competent 
to write it. With Whitman, more than with most men, one felt 
that the inner life was the dominant factor, that it was genuine, 
deep and worth knowing; the outward events were more or less 
accidental; he would have created similar effects under a totally 
different set of external circumstances. 
In person he was of medium height, of stout build and good 
color in his maturity, though thin and pale in his last years; his 
hair was snow white from young manhood, his eyes were direct 
and piercing, his forehead high, broad and noble; he wore a beard 
and a heavy mustache that somewhat concealed the rather thick- 
lipped mouth. His bearing was always erect and dignified; his 
dress was simple and sufficiently conventional, but he entirely 
eschewed the ceremonial dress and was only once seen in academic 
cap and gown, and I believe not at all in evening dress.
