PAGET'S SURGICAL PATHOLOGY.

[Continued.]

Mr. Paget embraces in bis theory the doctrine of complemental
nutrition, first taught by C. F. Wolff, illustrating the subject as
follows :

“ A great change in nutrition rarely takes place in a single
organ at a time ; for example, the growth of the beard at the
period of puberty in man, the growth and perfection of the plum-
age of the bird at breeding time ; but as in man, when the
development of the genital organs is prevented, that of the beard
and all other external sexual characters is, as a consequence,
hindered, so in birds, when the breeding season ends, and the
sexual organs pass gradually into their periodic atrophy, at once
the plumage begins to assume the pale and more sober colors,
which characterizes the barrenness of winter.” He next refers
to certain interesting specimens presented to the museum by Sir
Philip Eger ton, showing the interesting fact, “ that if a buck be
castrated while his antlers are still covered with velt, their growth is
checked, they remain as if truncated, and irregular nodules of
bone project from their surfaces,” “The fact is not, hitherto,
explained ; it is inexplicable, by believing that the materials which,
in the formation of these organs of external sexual character, are
removed from the blood, leave or maintain the blood in the state
necessary for the further development, growth and active function
of the proper sexual or reproductive organs.” “ The concurrent
development of the thymus gland and air breathing organs during
the body’s growth of the thyroid gland and the brain, (instances
