plainly than does their comparison under the best microscope, or by the
aid of the best chemical analysis. Monkeys are liable to many of the
same non-contagious diseases as we are; thus Rengger (5.
Naturgeschichte der Saugethiere von Paraguay, 1830, s. 50.), who
carefully observed for a long time the Cebus Azarae in its native land,
found it liable to catarrh, with the usual symptoms, and which, when
often recurrent, led to consumption. These monkeys suffered also from
apoplexy, inflammation of the bowels, and cataract in the eye. The
younger ones when shedding their milk-teeth often died from fever.
Medicines produced the same effect on them as on us. Many kinds of
monkeys have a strong taste for tea, coffee, and spiritous liquors:
they will also, as I have myself seen, smoke tobacco with pleasure. (6.
The same tastes are common to some animals much lower in the scale. Mr.
A. Nichols informs me that he kept in Queensland, in Australia, three
individuals of the Phaseolarctus cinereus; and that, without having
been taught in any way, they acquired a strong taste for rum, and for
smoking tobacco.) Brehm asserts that the natives of north-eastern
Africa catch the wild baboons by exposing vessels with strong beer, by
which they are made drunk. He has seen some of these animals, which he
kept in confinement, in this state; and he gives a laughable account of
their behaviour and strange grimaces. On the following morning they
were very cross and dismal; they held their aching heads with both
hands, and wore a most pitiable expression: when beer or wine was
offered them, they turned away with disgust, but relished the juice of
lemons. (7. Brehm, Thierleben, B. i. 1864, s. 75, 86. On the Ateles,
s. 105. For other analogous statements, see s. 25, 107.) An American
monkey, an Ateles, after getting drunk on brandy, would never touch it
again, and thus was wiser than many men. These trifling facts prove how
similar the nerves of taste must be in monkeys and man, and how
similarly their whole nervous system is affected.
Man is infested with internal parasites, sometimes causing fatal
effects; and is plagued by external parasites, all of which belong to
the same genera or families as those infesting other mammals, and in
the case of scabies to the same species. (8. Dr. W. Lauder Lindsay,
Edinburgh Vet. Review, July 1858, page 13.) Man is subject, like
other mammals, birds, and even insects (9. With respect to insects see
Dr. Laycock, On a General Law of Vital Periodicity, British
Association, 1842. Dr. Macculloch, Silliman s North American Journal
of Science, vol. XVII. page 305, has seen a dog suffering from tertian
