Ape, and forms less of the outer border of the hemisphere ; in this respect the Bush- 
woman also occupies an intermediate position. On the other hand, the amygdalae, 
which are very small in the Bushwoman, are very large in the Ape ; whilst the biventral 
lobes are large in the former and small in the latter. The slender lobes are very broad 
in both ; the lower posterior lobes, broad in the Bushwoman, are very narrow in the Ape. 
The superior and inferior vermiform processes, especially the latter, are proportionally 
more marked in the Ape than in the Bushwoman, in whom they are smaller than in 
the European. The floccules, small in the Bushwoman, are well developed in the Ape. 
In none of these particulars, then, is the Bushwoman’s cerebellum intermediate between 
that of the European and the Chimpanzee ; nor is this the case in regard to the number 
of the laminae, for there are fewer on the whole in that animal even than in the Euro- 
pean, the particular excesses and deficiencies not appearing to be reducible to any rule. 
In accordance with the smaller bulk of this organ in the Ape, the laminae themselves 
are very much finer even than in the Bushwoman. 
In the Bushwoman the corpus dentatum is represented by a comparatively small 
oblong mass of grey matter, almost destitute of foldings, and having its internal white 
substance ill defined. Is this connected with the small size of the quadrigeminal bodies 1 
In the Chimpanzee this body is long and narrow, but its foldings are distinct. 
On the whole it may be said, judging from its transverse commissural fibres and its 
laminae, that, with the exception of the amygdala and floccule, and the grey matter of 
the corpus dentatum, the cerebellum in the Bushwoman is very well developed, and 
that, as an organ, it is far more completely evolved than the cerebrum. 
II. THE IDIOTS’ BRAINS, 
a. General Account of the Idiots. 
The female idiot came of a healthy family, and died at the age of 42, of phthisis. 
Her height was about (probably below) 5 feet; her weight is unknown, but she was 
well proportioned, with shapely limbs, and small well-made hands and feet ; she was 
never fat, and did not become emaciated until phthisis occurred. The general appear- 
ance of her microcephalic head, the form, size, and condition of the cranium, with other 
particulars, are described in Mr. Gore’s paper*. From that source, and from informa- 
tion since supplied by him, it appears that her senses were perfect, including the appre- 
ciation of heat and cold. She had memory both of persons and things ; she could say 
“child,” “mamma,” “morning,” and “good” with tolerable distinctness; in the report 
of Mr. Gore’s paper it is added, “ but without connexion or clear meaning.” In explain- 
ing this he writes, “ I think she had some, though probably a very imperfect knowledge 
or conception of the meaning of the words she used ; she certainly knew Avhat was the 
meaning of ‘ good,’ in relation to her own acts and conduct ; she was, however, quite 
incapable of anything like conversation.” It is stated that she could not count, and did
