as is necessary in walking, is unnatural. The natural position is on
all fours, the body anteriorly resting upon the knuckles. These are
greatly enlarged, with the skin protuberant and thickened like the sole

"They are expert climbers, as one would suppose from their organization.
In their gambols they swing from limb to limb to a great distance, and

five, or ten at most, being found together. It has been said, on good
authority, that they occasionally assemble in large numbers, in
gambols. My informant asserts that he saw once not less than fifty so
engaged; hooting, screaming, and drumming with sticks upon old logs,
