Now, however, as electrical investigation with greater skill 

 and minuteness demonstrated the truth of variety of function in 

 the cortex the way was open to resume the method of extirpa- 

 tion which had, since its partial failure in the hands of Florens, 

 fallen into disrepute; and it was found that removal of those 

 areas which under electrical stimulation evoked motor responses 

 prevented any subsequent voluntary functioning of the muscles 

 concerned. This observation has formed the point of dei)arture 

 for the fruitful labors of Goltz, Munk, Ferrier, Luciani, Seppilli, 

 Gotsch. Horsely, and a host of others whose efforts have resulted 

 in the enormous literature of our science. 



The subject of our notice. Professor Gustav Fritsch, was 

 born in 1838. After passing through the laborious years required 

 to complete a course in Gymnasium and University, Dr. Fritsch, 

 like so many of his famous contemporaries, sought to extend his 

 scientific experience by explorations in the new fields recently 

 opened. During the sixties he spent three years in South Africa 

 in collecting materials \\ hich have since been elaborated in a 

 number of scientific and po])ular works, and have formed the 

 basis of the familiar lectures, illustrated with lantern slides, with 

 which Professor Fritsch occasionally gracefully entertains a party 

 of friends. 



The results of the expedi:ion so far as they relate to general 

 anthropology, zoology and botany, were published under the 

 title •' Drei Jahre in Siid-Africa." ( Breslau, 1868.), which also 

 contams the itinery and incidents of the journey. In 1872 there 

 appeared Die Eingeborene Sud-.A.frikas, ( Breslau), which gives 

 a complete account of the native races of South Africa, and 

 colored plates illustrating the peculiarities of color, and an atlas 

 of sixty portraits. A popular description of South Africa ap- 

 peared in " Das Winen der Gegenwart," Band 34, ( Leipzig, 

 1885.), entitled Siid-Africa bis zum Zambesi. 



The title of the inaugural dissertation, De medullare 

 spinalio textura; Berlin, 1862, in which the prevailing views 

 of that time were summarized, indicated the direction in 

 which the African traveler vyas to find his permanent work. 

 In 1875 there appeared a magnificent folio, published with 

 the cooperation of the Berlin Academy of Sciences, en- 

 titled " Untersuchungen iiber den feineren Bau des Fischgehirn.'
