BRASN-WEIGHT AND SIZE IN RELATION 



equivalent — after making tlie requisite deduction for membranes 

 and fluids, — to a brain-weiglit of 63 oz. 



I have attempted in the following table to reduce to some common 

 standard such imperfect glimpses as are recoverable of the cranial 

 capacity of some distinguished men, of whose actual brain-weights no 

 record exists : 



TABLE III. 



CRANIAL CAPACITY OF DISTINGUISHED MEN, 



Some of the examples adduced in the above table appear to 

 exhibit instances of mental endowment of high character, without the 

 corresponding degree of cranial, and consequently cerebral develop- 

 ment. The following table exhibits recorded examples of a series 

 of actual brain-weights of distinguished men. It seems to lend con- 

 firmation to the idea that great manifestation of mental endowment 

 is correlated, in the majority of observed cases, to a brain above the 

 normal average in mass or weight. But even here intellect and 

 brain-weight are not "strictly in uniform ratio. Several of the fol- 

 lowing brain- weights, including that of Tiedemann, are furnished by 

 Wagner, in the " Yorstudien des Menschlichen Gehirns ;" but in 

 an elaborate table of brain- weights given in the " Morphologie und 

 physiologie des Menschlichen gehirns als Seelenorgan," the brain of 

 Byron is classed above all except Cuvier ; while Vogt gives the same 

 place, by estimate, to Schiller's, as next in rank to that of the great 

 naturalist among highly developed brains. Dr. Thurnam states his 

 authorities for others, when producing them in his valuable contri- 

 bution to the Journal of Mental Science " On the Weight of the 

 Brain." For that of Webster he refers to ''the unsatisfactory 

 article on the brain of Daniel Webster, Hdin. Med. Surg. Jotorn., 

 vol. Ixxix., p. 355." Dr. J. C. ISTott, in his " Comparative Anatomy
