XXXVI LIFE OF DR. ROLLESTON. 



poses, which the schoolmen had expressed in the wider words 

 1 Nusquam magis quam in minimis tota est natural and which we 

 might express in plain English by saying that 'Small things 

 speak plainly of great issues/ the general public had been right 

 in clinging to such a structure as was the hippocampus minor as 

 a mark and means for differentiating man from the apes. As, 

 however, this nodule of neurine had been rent away from their 

 hands, it was right that something should be supplied to take 

 its place. The analysis of the brain's structure had established 

 as differentiative between man and the ape four great differ- 

 ences — two morphological, two quantitative. The two quantita- 

 tive, which we can detect without having recourse to Gratiolet's 

 method, are the great absolute weight and the great absolute 

 height of the human brain. The two morphological are the 

 niultifidity, the great complexity and evolution of the frontal 

 lobes corresponding to the forehead, usually, popularly, and as 

 this analysis shows, correctly, taken as a fair exponent of mans 

 intelligence — and the presence in the apes and absence in man of 

 the deep cleft, ' the external perpendicular fissure,' in the posterior 

 part of the hemispheres. No reference to these important matters 

 of Gratiolet's analysis had been made by Professor Owen, and 

 this omission could not fail to put the British Association's repute 

 for acquaintance with the work of foreign fellow-labourers at 

 great disadvantage in the eyes of such foreigners as might be 

 present. Professor Rolleston concluded by saying that if he had 

 expressed himself with any unnecessary vehemence he was sorry 

 for it, but he felt there were things less excusable than vehemence, 

 and that the law of ethics and love of truth were things higher 

 and better than were the rules of etiquette or decorous reticence. 

 Among the notices of this speech of Rolleston's, which made 

 considerable impression, is a mention of it in Kingsley's squib 

 ' Speech of Lord Dundreary in Section D. on Friday last, on the 

 Great Hippocampus Question.' This, which rather well represents 

 the perplexity of the lay mind at an abstruse anatomical dispu- 

 tation, is republished in Kingsley's ' Life,' chap, xix, and followed 

 by a letter written to Rolleston by Kingsley (Oct. 12, 1862), who
