for sweet things—their capacity for fruit, even the most hard 
and unripe—their love of stealing, of hiding away in corners 
to eat—these are not the result of mere cussedness on their 
part, but are characteristics inherited from monkey-like 
parents—characteristics which would have been the natural 
accompaniment of life in the woods, where they would have to 
spring from tree to tree, to get what food they could and how 
they could, and to possess, advisedly, a wholesome fear of 
strangers. 
Further, take the manner in which our infants are got off 
to sleep—by rocking them in the arms or in the cradle. This, 
it seems to me, is an inheritance of monkeyhood ; and the fond 
mother, while scorning the very idea of her darling being in 
any way connected with a monkey, gives you fair excuse for 
coming to a contrary conclusion when she imitates the to-and- 
fro swaying of the branches, and rocks her baby to sleep in the 
cradle, singing the while— 
“ Lull-a-by baby on the tree top 
When the wind blows the cradle shall rock,” 
“Whether some lingering tradition of a former arboreal 
life inspired the idea of this ditty I cannot say ; but, undoubt- 
edly, it fairly describes the kind of rest a monkey would have 
among the swaying branches. And the swaying of the 
branches would have become as important and absolutely 
necessary for the sound sleep of a monkey, as the motion of 
the vessel becomes to the repose of sailors—they make com- 
plaint of their inability to sleep soundly on land after a long 
voyage. 
There are numerous other actions and habits peculiar to 
children which we call natural, simply because we are so 
accustomed to see children perform them, though why they 
should do so is not a question very often put. If, however, we 
consider that infants and children are the morphological repre- 
sentation of monkey-like ancestors and of savage Man, and if 
we think that some of the habits of the earlier stage would 
persist into the later stage partly by inheritance, partly by
