STUDY OF BRAINS OF SIX EMINENT SCIENTISTS AND SCHOLARS. 185 



cavity. Compared with the cerebro-cerebellar ratio in average brains, Grote's cerebel- 

 lum was relatively small. 



The general form of the cranium was brachycephalic but it was decidedly higher 

 than usual. The cerebrum itself was, in accordance with the shape of the cranium, 

 short, broad and deep. The frontal lobes appeared to be very long on their upper 

 surface, very wide in front of the sylvian fissure and both long and broad on their 

 under sui'face. The parietal lobes were short and wide. The temporal lobes were also 

 wide though short. The occipital lobes were small and shallow. Tiie cerebral con- 

 volutions were very massive, being not only broad and deep, but well folded and 

 marked with secondary sulci, especially in the frontal and parietal regions. Marshall 

 states that the callosum was so long that its sectional area was unusually great ; and 

 he concludes from the size of the convolutions, the sufficiency of gray matter and from 

 the remarkable number of the white fibers, especially of the transverse commissural 

 ones, that the brain of Grote must be pronounced to have been of very perfect and high 

 organization. Grote's stature was 179 ctm. By descent he was half English, one 

 quarter German and one quarter French. John Marshall : " The Brain of the late

37. De Morgan (1798-1871), English mathematician (London collection?). The 

 brain was examined by Dr. H. C. Bastian and Dr. Wilson Fox on the third day after 

 death. The brain-weight was 52il ounces (1,494 grams). Professor De Morgan had 

 an exceptionally large head. Bastian's measurements are as follows : 



Inches. Centimeters. 



Head circumference 245 63 



Arc, root of nose to occipital protuberance .... 151 39 

 Ear to ear over vertex 15i 39.3 



"As a consequence apparently of a blindness of the right eye, dating from a few 

 days after birth, the left cerebral hemisphere of De Morgan's brain was smaller than 

 the right. . . . Except for a degenerated condition of the right optic nerve and the 

 corresponding left optic tract there is nothing to be discovered which can possibly 

 account for the smaller size and stunted development of the left hemisphere." Cer- 

 tain measurements of the hardened specimen are given. C. Bastian : "The Brain as

38. Agassiz, Louis (1817-1873), American naturalist (French descent). The 

 autopsy was reported by Dr. Morrill Wyman. "The weight of the brain was 53.4 

 ounces" (1,514 grams). Drs. .J. J. Putnam and R. H. Fitz were present. The antero-
