This numerous order of animals is divided into three families: 1.
_Apes_, which are destitute of tails; 2. _Baboons_, having short tails;
3. _Monkeys_, having long tails. The whole group are confined to warm
countries, and none but the latter kinds are met with in America. They
are not found in Europe, except at Gibraltar. Here, among the rocks,
are considerable numbers of apes; and it has been conjectured that they
come hither from the African coast, by means of passages under the
Straits. This idea, however, is groundless. No doubt these animals were
once common in Europe; but they have been gradually extirpated, except
at Gibraltar, where they have made a stand. Its rocks and caverns seem
to have proved as impregnable a garrison to them as to the British.
