of the patriarch have to be restricted; a bar has to be raised to
prevent his adding his daughters to his wives. Only by overcoming this
habit of paternal incest can further social evolution become possible.

On this question I shall give the explanation of Mr. Atkinson; and it
is with real regret that the limit of my space makes it impossible to
quote in full his own words.[37] The change came by _the entrance of
outside suitors as husbands for the daughters and their acceptance as
group-members_.

pp. 250-263.

At this point a difficulty once again arises. By what means was the
patriarch brought to accept the presence of these young intruders,
thus usurping his sexual rights over his daughters? Mr. Atkinson
believes this could not have taken place during the life of the
patriarch. "The initiative in change must have arisen irrespective of
him, or without his presence." Here Mr. Atkinson appears to me to fall
into error, as once more he neglects to consider the effect of the
young women's own desires. I hold that, by this time, the
group-daughters, supported by their mothers, must have been strong
enough to outwit their father (whose authority already had been
weakened), if not openly, then by deceiving him. They would now see
their brothers living with young wives. Is it credible, I ask, that
they would remain content with the sexual embraces of their father?

In this connection it is of interest to note the opposition sometimes
offered by young females to the advances of an old male among the
families of monkeys. I have received quite recently an account of such
a case in a letter from my friend, Max Henry Ferrass, formerly
Inspector of Schools in India, and the author of a valuable work on
Burmah. This is what he says--

"I once was able to observe a herd of common long-tailed
monkeys of the Indian plains at play on a sandbank in a
river. There were about fifty of all ages. There was one
great bully among them who looked double the size of the
average adult--and must have been double the weight, at any
rate--whose sport was to chase the young females. They,
knowing his game, fled before him, but he caught them
readily. But before he could have his will of any, she would
bound from his grasp as if stung, and always escape, as this
sudden spurt of energy was more than he could control."
