14 PROCEEDINGS OF WASHINGTON MEETING. 



The glacial deposits seem to have a much greater extent in South America than 

 has been supposed. In the Cordillera of Capiajo moraines are found at a height of 

 about 1,200 meters above sea level, and Raimondi, twenty years ago, described the 

 same deposits from the department of Ancachs, in Peru (about ( .»° south latitude), 

 reaching down to about 2,500 meters above sea level. These facts merit our atten- 

 tion with regard to the theory concerning the alteration of the terrestrial axis or 

 the contemporaneity of the glacial periods on both hemispheres. 



The paper was discussed by E. D. Cope, R. T. Hill, and C. A. White. 

 Mr. Hill thought there would probably be found some correspondence 

 between the Cretaceous of the western coast of South America and that 

 of the United States. Dr. White spoke as follows : 



My own investigations with relation to South American geology, to which Dr. 

 Steinmann has referred, have been confined to the Cretaceous invertebrates of Brazil. 

 When studying the fauna, which was collected by members of the survey under 

 Professor Hartt and sent to me for that purpose, I was not able to identify a single 

 species with any North American form. Neither was I able to detect any close 

 affinity between the Brazilian fauna and that of any North American formation. 

 On the contrary, I found that a considerable number of the Brazilian forms were 

 closely like a part of the Cretaceous fauna of southern India, and some of the 

 species 1 treated as being identical. I was not then, and am not now, able to say 

 that all the species which were sent to me came from one and the same stage of 

 the Cretaceous series. If they did, there is certainly a remarkable commingling of 

 earlier and later Cretaceous types. I do not think such a commingling is improb- 

 able, and I therefore treated the collections sent to me as a faunal unit, and in sum- 

 ming up all its characteristics I referred it to the Neocomian. 



In reply to questions Dr. Steinmann said that enormous beds of 

 eruptive material were found between thin bands of limestone ; that 

 continuous eruptions of all kinds of volcanic rocks took place in the 

 Chilean cordillera during Jurassic and Cretaceous time. In eastern Brazil 

 there is conformity between the Carboniferous and the lower Cretaceous, 

 which rests upon the former. The Paleozoic rocks are metamorphosed ; 

 the later are not. 



The full paper is printed in the American Naturalist, vol. xxv, 1891, 

 pp. 855-800. 



The next paper was entitled— 



ON THE PERMIAN, TRIASSIC, AND JURASSIC FORMATIONS IX THE EAST INDIAN 



ARCHIPELAGO (TIMOR AND ROTTl). 



13Y DR. AUGUST ROTIIPLETZ, OF THE UNIVERSITY OF MUNICH, GERMANY. 



In discussing this paper Dr. C. A. White remarked : 



The paper which has just been read by Dr. Rothpletz is of peculiar interest to me 

 because some late studies of mine in Texas are of a similar character. These dis- 

 coveries in their essential character are similar to those of Waagen in India,
