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
