arrangement of the furrows upon the surface of the cerehral hemi- 

 sphere. Nevertheless many of them can he detected, if not by 

 sight, by passing the finger over the surface and locating the 

 depressions by touch. These features are represented (with con- 

 siderable exaggeration so far as depth of shading is concerned) in 

 the diagram (fig. 11) on the preceding page. 



At first sight, the brain presents a considerable resemblance to 

 the well-known Palaeolithic brain-casts, and especially to those 

 obtained from the Gibraltar and La Quina remains, which are 

 supposed to be women's. Like these casts this one is relatively 

 long, narrow, and especially flat ; but it is smaller, and presents 

 more primitive features than any known human brain or cranial 

 cast. 



The position and relations of the cerebellum present a marked 

 contrast with those exhibited in the La Chapelle-aux-Saints, 

 La Quina, and Gibraltar casts ; the frontal and parietal regions 

 are less expanded, and the temporal region exhibits some important 

 and very significant differences. 



The length of the left cerebral hemisphere (which was probably 

 a little longer than the right, because the left occipital pole was 

 the more prominent, a condition found in the brains of modern 

 right-handed men) J is 163 mm. The breadth in the frontal region 

 (just below the point marked a) is 101 mm. : the maximum breadth 

 of the hemispheres is at the point T, low down on the temporal area, 

 and measures 130 mm. ; but at the point P in the parietal region, 

 corresponding to the place where anthropometrists measure the 

 breadth of the skull, the breadth of the brain-cast is only 102 mm. 

 The maximum height, measured from the [restored] tip of the 

 curiously pendent temporal region (designated ' Polus temporalis 

 inferior/ to distinguish it from the temporal pole of the modern 

 man's brain), is 106 mm. ; but farther back (opposite T) the height 

 sinks to 86 mm. 



In this note I do not propose to discuss the significance of the 

 faint glimmerings which this cast affords of the pattern of the con- 

 volutions, except to remark that there are indications sufficiently 

 definite to enable us to plot out a great part of the singularly 

 primitive arrangement of sulci. 



I have already referred to the diminution and flattening of the 

 frontal and parietal regions. In the centre of the latter there is 

 an area, which is well circumscribed by recognizable sulci (s, n, I; 

 v, and o«), raised up into a low hillock, the summit of which is at 

 the point marked P. It is more pronounced on the right hemi- 

 sphere. This indication of the expansion of an area, the large 

 dimensions aud fulness of which are especially characteristic of 

 the human brain, is peculiarly significant, when taken in con- 

 junction with a similar condition in the temporal region. 



One of the most striking features of this brain-cast is the deep
