The Descent of Man

These glands secrete a semi-fluid fetid matter
which is sometimes so copious as to stain the
whole face, as I have myself seen in an antelope.
They are "usually larger in the male than in
the female, and their development is checked
by castration." (11. Owen, 'Anatomy of Vertebrates,'
vol. iii. p. 632. See also Dr. Murie's observations
on those glands in the 'Proc. Zoolog.
Soc.' 1870, p. 340. Desmarest, 'On the Antilope
subgutturosa, 'Mammalogie,' 1820, p. 455.) According
to Desmarest they are altogether absent
in the female of Antilope subgutturosa. Hence,
there can be no doubt that they stand in close
relation with the reproductive functions. They
are also sometimes present, and sometimes
absent, in nearly allied forms. In the adult male
musk-deer (Moschus moschiferus), a naked
space round the tail is bedewed with an odoriferous
fluid, whilst in the adult female, and in
the male until two years old, this space is covered
with hair and is not odoriferous. The proper
musk- sack of this deer is from its position
