e telescopic eyes which monkeys share with a few species
of birds, but with hardly any of their mammalian relatives, except man
in a state of nature. Mentally it manifests itself in a marvellous
faculty for anticipating danger. Last summer Sally, the above-mentioned
baboon, contrived to break loose, and took refuge on the top of the
roof. I do not believe that she intended to desert, but she was bent on
a romp, and had made up her mind not to be captured by force. A chain of
eight or nine feet dangled from her girdle, and she persistently avoided
approaching the lower tier of shingles, to keep that chain from hanging
down over the edge, but was equally careful not to venture too near the
extremities of the roof-ridge, for there was a skylight at each gable.
She kept around the middle of the roof; and we concluded to loosen a few
shingles in that neighborhood and grab her chain through the aperture,
while a confederate was to divert her attention by a continuous volley
of small pebbles. But somehow Sally managed to distinguish the
hammer-strokes from the noise of the bombardment, and at once made up
her mind that the roof had become untenable. The only question was how
to get down; for by that time the house was surrounded by a cordon of
sentries. As a preliminary measure she then retreated to the top of the
chimney, and one of our strategists proposed to dislodge her by loading
the fireplace with a mixture of pine-leaves and turpentine. But better
counsel prevailed, and we contented ourselves with firing a blank
cartridge through the flue. Sally at once jumped off, but regained her
vantage-ground on the roof-ridge, and we had to knock out a dozen
shingles before one of our fourteen or fifteen hunters at last managed
to lay hold of her chain.

The naturalist Lenz describes the uncontrollable grief of a Siamang
gibbon who had been taken on board of a homebound English packet, where
his owner tempted him with all sorts of tidbits, in the vain hope of
calming his sorrow. The gibbon kept his eye on the receding outline of
his native mountains, and every now and then made a desperate attempt to
break his fetters; but when the coast-line began to blend with the
horizon the captive's behavior underwent a marked change. He ceased to
tug at his chain, and, chattering with protruded lips, after the
deprecatory manner of his species, began to fondle his owner's hand, and
tried to smooth the wrinkles of his coat, with the unmistakabl
