transverse gyres above mentioned, the ventral tier of the niedifrontal is particularly 

 broad while the subfrontal is quite well convoluted. 



3fesal Surface. — The superfrontal gyre, on its mesal aspect, is distinctly divided 

 into two tiers by the long and continuous frontomarginal fissure. The paracentral 

 gyre is 4.5 cm. in length. The callosal gyre presents nothing unusual. 



Fissures of the Parietal and Occipital Lobes [Lateral Siirface). The Postcentral Fis- 

 sitral Complex. — The postcentral and subcentral together form a moderately sinuous 

 fissure from which the parietal fissure arises. Dorsally the postcentral terminates in 

 a T-shaped bifurcation. The total length is 7 cm. The parietal fissure is sliort, ter- 

 minating caudad in a bifurcation, each of the furcal arms being again bifurcated. 

 There is a well-marked transparietal. The paroccipital becomes continuous caudo- 

 laterad with several fissures in the parieto-occipital region. 



Mesal Surface. — The precuneal fissure is irregularly zygal and is joined by the 

 intraprecuneal extension of the transparietal. A curved cuneal fissure, independent, 

 marks the cuneus. There is a zygal postcuneal fissure. 



Gyres of the Parietal and Occipital Lobes. — The postcentral gyre is, in general, a 

 trifle narrower than its fellow on the left side. The parietal gyre is of good width ; 

 the paroccipital is quite complexly convoluted. The subparietal district is extremely 

 large as is shown by the great encroachment of this area upon the sylvian fissure. 



The precuneus is of good size. The cuneus is relatively small. 



Fissures and Gyres of the Te^npoo-al Lobe. — The super temporal fissure is repre- 

 sented by two segments, a short one at the temporal apex, a longer one caudad. Its 

 caudal extension is considerably abbreviated. The meditemporal and subtemporal 

 fissures are represented by several segments difficult to trace clearly. The tendency 

 to transverse anastomoses of the fissures and their frequent interruption by transverse 

 or oblique gyral isthmuses is very marked in the entire temporal lobe. 



A BRIEF DESCRIPTION OF THE SKULL OF PROFESSOR E. D. COPE. 



The skull is in fairly good condition. The calva has been separated by a saw- 

 cut, and a portion of the parietal bone in the left temporal fossa is missing. The 

 specimen is remarkable on account of the proportionately large size of the cranium as 

 compared with the face, in this respect approaching the notable skull of Kant. Tlie 

 bones are thin but of considerable hardness and density. The alveolar processes of 

 both jaws are absorbed to a considerable degree, serving to accentuate the relative 

 smallness of the facial portion. 



The parietal bones are notable for their expanse ; the temporal ridges pass con- 

 siderably ventrad of the middle of the bone ; less than one-third of the parietal lies
