these feats to save their lives. During the felling of the forest near 
this village, a small colony of Siamangs got isolated on a tree separated 
from the next clump by some thirty feet or so. They scampered up 
and down in the crown of the tree howling in the most abject terror 
at every stroke of the axe; yet they would not venture to leap the 
intervening space, and even, when the tree was falling, they did not 
attempt to save themselves by springing on the ground but perished in 
its downfall. * * * During my march to the coast my Siamang 
accompanied me, occupying with the most grave demeanor a seat on 
one of the packages carried in the rear near to myself. Here it 
sheltered its head to the amusement of all whom we met, under a 
Chinese umbrella, which I had bought for it to protect it from the 
midday sun, and for which, after every halt, it held out its hands in 
the most knowing way, screaming lustily if the porters dared to move 
on before it had comfortably arranged itself. To my intense regret a 
misadventure put an end to a most charming existence before I could 
send it to London.”

This animal in outward appearance is exactly like the Sumatran 
species, the only difference being that the skull is slightly smaller, with 
the corresponding reduction in its various parts. The tooth row is 
shorter, but of the two skulls of this race as yet obtained, the difference 
in the length of their tooth rows is as great as is that between the 
longest of them and that of the Sumatran Ape; and they are all adult 
individuals if not even aged. It requires a large number of crania.
