is more striking in a coralline than in a tree. Our conception
of a compound animal, where in some respects the individuality
of each is not completed, may be aided, by reflecting
on the production of two distinct creatures by bisecting a
single one with a knife, or where Nature herself performs
the task of bisection. We may consider the polypi in a
zoophyte, or the buds in a tree, as cases where the division
of the individual has not been completely effected. Certainly
in the case of trees, and judging from analogy in that of
corallines, the individuals propagated by buds seem more
intimately related to each other, than eggs or seeds are to
their parents. It seems now pretty well established that
plants propagated by buds all partake of a common duration
of life; and it is familiar to every one, what singular and
numerous peculiarities are transmitted with certainty, by
buds, layers, and grafts, which by seminal propagation never
or only casually reappear.

[1] The desserts of Syria are characterized, according to
Volney (tom. i. p. 351), by woody bushes, numerous rats,
gazelles and hares. In the landscape of Patagonia, the guanaco
replaces the gazelle, and the agouti the hare.

[2] I noticed that several hours before any one of the condors
died, all the lice, with which it was infested, crawled to the
outside feathers. I was assured that this always happens.
