    described, but that of the fibres also. The human brain is compared with that of the two apes, and the clinical, patho- logical, and experimental evidence is fully discussed in its relation with the histological results. An excellent series of papers on the cell lamination have been published by Brodmann in the c Journal f. Psychologie und Neurology,’ 1903 and onward, and summarised in his book, ‘ Vergleichende Lokalisations lehre der Grosshimrinde,’ Leipsig, 1909. The human brain is described in great detail, a very large number of separate areas (more than fifty) being distinguished histologically. Similar detailed descriptions of the brains of Cercopithecus and of the lemurs are given, while the marmoset (Hapale) is dealt with more shortly. The homo- logies between different regions in the human and other Primate brains are dealt with as far as possible. Mott and Kelley publish a “Complete Survey of the Cell Lamination of the Cerebral Cortex of the Lemur” Proceed- ings of the Royal Society,’ B., vol. lxxx, 1908), in which the histological results are compared with the results of stimula- tion experiments performed on the lemur’s brain by Prof. Halliburton, and a paper of a similar nature, but dealing with the brain of the marmoset, has been produced by Mott, Halliburton, and the present author (Mott, Schuster, and Halliburton, “Cortical Lamination and Localisation in the Brain of the Marmoset,” ‘ Proceedings of the Royal Society,’ B., vol. lxxxii, 1910). Material and Methods. The material used in the present paper consisted of the brain of a specimen of Papio hamadryas which had died in the gardens of the Zoological Society. Each hemisphere was cut into a number of blocks (seventy or more), arranged in such a way as best to secure that as much as possible of the cortex was cut in planes at right angles to its surface, since in oblique sections the nature of the cell lamination is almost impossible to determine.
