THE BABOONS. 257 
Leopard at defiance, and when*in a large body, they do not, 
it is said, fear the Lion.” 
‘“Baboons often show their passion,” as Mr. Darwin has 
related, ‘“‘and threaten their enemies in a very odd manner, 
namely, by opening their mouths widely, as in the act of 
yawning. Mr. Bartlett has often seen two Baboons, when first 
placed in the same compartment, sitting opposite to each other, 
and then alternately opening their mouths; and this action 
seems frequently to end ina real yawn. Mr. Bartlett believes 
that both animals wish to show’to each other that they are 
provided with a formidable set of teeth, as is undoubtedly the 
case. As I could hardly credit the reality of this yawning 
gesture, Mr. Bartlett insulted an old Baboon and put him 
into a violent passion ; and he almost immediately thus acted. 
Baboons likewise show their anger, as was observed 
by Brehm with those which he kept alive in Abyssinia, in 
another manner, namely, by striking the ground with one hand, 
‘like an angry man striking the table with his fist.’ I have 
seen this movement with the Baboons in the Zoological 
Gardens ; but sometimes the action seems rather to represent 
the searching for a stone or other object in their beds of straw. 
With several species of Baboons, the ridge of the fore- 
head projects much over the eyes, and is studded with a few 
long hairs, representing our eyebrows. These animals are 
always looking about them, and in order to look upwards they 
raise their eyebrows. ‘They have thus, as it would appear, 
acquired the habit of frequently moving the latter. However 
this may be, many kinds of Monkeys, especially the Baboons, 
when angered, or in any way excited, rapidly and incessantly 
move their eyebrows up and down, as well as the hairy skin of 
their foreheads,”
