MEMORIAL OF ALEXANDER WINCHELL. 13 



not all the time active in the fighting camp of the fray, but he was always 

 in the great contest. He was organizing the forces, and laying far-reach- 

 ing plans for campaigns which the future alone will work out ; he was 

 rallying the reserves by public enlightenment on the issues and utility 

 of all science. He increased our friends and disarmed our foes. He 

 propitiated many who were hostile or indifferent. His influence was 

 felt where it was little suspected. The next generation, scanning the 

 history of the present, will detect the agency which he bore out in the 

 scientific and particularly in the geologic movements of this, and the 

 next century can best point out the men who, in the closing years of the 

 nineteenth century, bore the great burdens and discharged the great 

 functions on which the progress of truth and the increasing happiness of 

 man depend. 



Following the reading of the memorial, it was moved by Professor 

 Charles R. Van Hise and unanimously voted that a special committee 

 of three be appointed to prepare and submit to the Society resolutions 

 in expression of the sentiments of the Society regarding the death of 

 President Winchell. The chair appointed as such committee Edward 

 Orton, Charles A. White, Charles R. Van Hise* 



No reports of committees were presented and no miscellaneous business 

 was offered. After announcements regarding the sessions of the Society 

 and of the approaching International Geological Congress, Acting Presi- 

 dent Gilbert declared the scientific work of the meeting in order, and 

 announced the first paper upon the printed program : 



A GEOLOGICAL MAP OF SOUTH AMERICA. 



BY PROP. DR. GUSTAV STEINMANN, OF THE UNIVERSITY OF FREIBURG, GERMANY. 



(Abstract.) 



This geological map of South America forms a part of the geological section of the 

 " Physikalischer Atlas von Berghaus" (Gotha: J.Perthes). There are many re- 

 semblances which have existed between the two Americas up from Paleozoic time. 

 So the Devonian fauna of Bolivia connects the North American faunas of that age 

 with those of Brazil, Falkland islands, and South Africa. In both regions, during t lie 

 Triassic and Jurassic periods, marine deposits were not formed on the greater part 

 of the continent, hut at the commencement of the ( Iretaceous period large areas were 

 covered by the sea, especially in the northern pari of South America i Brazil, Colom- 

 bia, Venezuela, etc. ) and in the southern part of North America Mexico, Texas, etc. . 

 In southern Chile there exists a continuous series, partly of Cretaceous and partly of 

 Tertiary age, w hich seems to be analogous to the ( !hico-Tejon group of ( 'alifm'nia.
