having very adroitly popped the fruit into his cheek-pouches, had moved off a few yards, when a boy in the crowd round him pulled him sharply by the tail. Conscience-stricken, he fancied that it had been done in revenge by the date-seller whom he had robbed; and so, passing close by the true offender and behind the legs of two or three others, he fell on the unfortunate fruiterer, and would no doubt have bitten him severely, but for the interference of his master, who came to the rescue.” Although so clever, the Hamadryas is much more deficient in brain than the higher Apes, the Orang for instance. It is not so much developed in front, and the whole mass is not so high, but still it projects well over the little brain, or cerebellum. The convolutions are simpler, and although all the principal markings noticed even in man are present, still the smaller ones, and those which belong to structures which add to the superficial extent of the organ, are wanting. The ventricles and the posterior horn and its eminences are present, as is also that particularly monkey development, the fissure, which is called the external perpendicular. Evidently the compressed form of the skull, which seems as if it had been pressed far above over the forehead, has much to do with the small bulk of the front of the brain, and this is also diminished by the projection of the orbits into the brain-case. The skull is certainly an ugly thing to look at, and is only surpassed by that of the full-grown Mandrill in want of elegance, of outline, and smooth configuration. The forehead and top of the skull are broad and flat, and the whole brain-case appears to slope off at the sides of the orbits, and then projects but little there, the broadest part of the skull being at the cheek-bone. The orbits are oblique, that is to say, they look forwards and outwards, and they are tolerably widely open. There is a great roundness and swelling of the upper jaw-bone from the cheek-bone to the long nasal bones, and the front jaw-bone (the pre-maxillary) is short and projecting. The shape of the skull resembles that of the Sphinx Baboon. Their name, given to them by the naturalist, is as great a puzzle as are many others devoted to animals, for what possible connection can there be between the Hamadryads, the nymphs whose birth, life, and death were mysteriously united with the corresponding epochs in the growth of the oak-tree, and a most un-nymphlike creature which likes rocks, holes, and dens, but who neither cares for oaks nor acorns?
