it very often is, in well-developed skulls (' Med. Chir. Review,' 

 April, 1863, p. 508). In well-developed human brains the poste- 

 rior parts of the upper frontal x convolutions, as also the lobule of 

 the second ascending parietal convolutions, are largely developed ; 

 whilst the first ascending convolution and the fissure of Rolando 

 (Thurnam, 'Nat. Hist. Rev.' 1865, p. 367) remain as lines of 

 indifference between them, along which no stimulus is propagated 

 to the outer pericranium, and no absorption of the tabula vitrea 

 inside excited. Both the posterior coronal furrow and the furrow 

 at right angles to it in the posterior portion of the sagittal suture 

 are present, though but faintly indicated, in the Dinnington cast 

 I have spoken of. 



It is not beside the purpose to add here that Retzius (' Ethnolo- 

 gische Schriften,' p. 108, 1864) distinguished these two varieties 

 of Celtic crania from each other as emphatically as I have striven 

 to do. After describing a long narrow and laterally compressed 

 skull, which he says is specially found in England and France, 

 and which obviously corresponds to the ordinary long barrow or 

 Hohberg type, he says, ' Nevertheless this is not the common 

 Celtic form, which is ordinarily somewhat broader and not so 

 compressed, whilst the " Cimbric " Celtic form, which is here and 

 there found in South Sweden and Denmark, is somewhat broader 

 still. This form is very like the Scandinavian Gothic' Both 

 these forms of crania seem to me to be different from the Roman 

 form of cranium which may be seen figured from Maggiorani 

 in Von Baer's paper on the Rhaetians in the ' Bull. Acad. Imp. 

 Sci. St. Petersbourg,' i860, p. 58. This form of cranium however 

 I am enabled to say, a specimen from the Towyn y Capel tumulus 

 having been presented to the University Museum by the Hon. 

 W. O. Stanley, coexisted with the River Bed type in this island, 

 just as this latter coexisted and apparently peacefully with Retzius' 

 f Common Celtic' form in the Frilford cemetery, and with the 

 'Brachycephalic Celt' form of Dr. Thurnam in a barrow at Crawley. 

 Finally, the platycephalic Roman form as figured and described by 

 Maggiorani and Sandifort (Ecker, ' Crania Germaniae,"' p. 86) is 

 very precisely and abundantly represented in the series obtained 

 by me from the barrow at Dinnington, where it coexisted with both 

 the longer forms of Celtic crania. Of this barrow, as it is now so
