638 GENERAL REMARKS 



line of the vertical arch as viewed in the norma lateralis dips into 

 the posterior aspect of the skull at a point very little behind the 

 plane of these tubera. The skull, in other words, and from another 

 point of viewing it, that namel}^ of the norma verticalis, rounds 

 itself off somewhat abruptly from the level of the parietal bosses, 

 instead of tapering as in the other type somewhat gradually 

 towards the squama occipitis. This latter portion of the posterior 

 aspect of the skull is not, as usually stated, by any means in- 

 variably flat ; it is, on the other hand, very frequently markedly 

 convex, the more markedly so, of course, on account of the flatten- 

 ing of the parietals to form the dip into the back aspect of the 

 skull. As above pointed out in the description of the skull 

 ' Cowlam ' (lix. 3, p. 226), p. 589, note 2, the occipital squama may 

 so project as to constitute what has been called a ^capsulares Hinter- 

 haupt ' in typically brachy-cephalic crania. In casts of such skulls 

 the parts of the brain which were lodged in the fossse of the superior 

 squama occipitis may be seen to project as well defined mamillary 

 out-growths beyond the plane of the curve of the upper part of the 

 posterior aspect of the cerebral lobes, and to overlap the cerebellum 

 proportionately ^. Now it was shown long ago by Buschke (in his 

 Schadel, Hirn und Seele, 1854, p. 142), and has been repeatedly 

 confirmed since by other investigators of the relations of the brain 

 to the brain-ease, that the parietal eminence covers a particular 

 lobule in the brain beneath it, the lobule, to wit, which is called 

 by Gratiolet in his better known ^ Memoire sur les Plis C^rebraux, 

 p, 60, the ' lobule of the marginal convolution ; ' and which is called 

 by Huschke, l. c, the ' lobulus tuberis.' Similarly Huschke (pp. 62 

 and 142) pointed out that a particular part of the brain was limited 



' See p. 573, note, supi'a, and compare figure of skull from Wetton Hill Barrow, 

 Cran. Brit. xiv. pi. 12, and pi. 16 and 27 : and in ' Crania Helvetica,' E. xvi. and xvii. 



^ Huschke, owing to certain faults of style and arrangement, and also to bis investi- 

 gations of facts being very lai-gely interlarded witb questionable philosophy, has not 

 obtained all the credit which his laboriousness merited. Besides allocating the lobulus 

 tuberis, and the occipital lobes proper, to particular parts of the skuU, be also defined 

 the true position of the fissure of Rolando relatively to the coronal suture, p. 139, 

 and that of the superior frontal gyrus relatively to the frontal tubera, p. 154, in the 

 same year in which Gratiolet, /. c. p. 101, wrote as follows : ' La boite cranienne forme 

 une vaste et libre cavite. C'est une volite sons laquelle les plis et lobes c^rt'braux 

 s'avancent, se reculent, s'etalent, se resserrent, s'c^cartent, se refoulent; ces mouve- 

 ments, n'ayant aucune relation absolue avec les Elements dont cette voflte se compose ! ' 



Huschke's own countrymen, to whom bis writings must be easier reading than they 

 are to readers of other nationalities, have not always rendered him full justice. Pro- 

 fessor Meynert however forms an exception to this rule; see his paper on Die 

 Windungen der convexen Oberflache des Vorderhirns, Archiv f iir Psychiatric, bd. vii. 

 hft. 2. "'
