After a brief stop in Brazil, Argen- 

 tina was reached in May, 1910, and the 

 stay of the writer in the country lasted 

 two months, while that of Mr. Willis 

 was somewhat longer. The Argentina 

 men of science received us very cordial- 

 ly and facilitated our work with a great 

 liberality. Florentino Ameghino and 

 brother Carlos, Lehmann-Nitsche and 

 Santiago Roth were particularly helpful. 

 The specimens which it was important to 

 examine, even those the descriptions of 

 which had not yet been published, were 

 placed freely at our disposal; Ameghino 

 and his brother accompanied us notwith- 

 standing the inclement season for nearly 

 three weeks from point to point along the 

 bleak coast where vestiges of ancient man 

 or his forerunners were believed to have 

 been discovered, and Roth, de Carles 

 and others went with us to more distant 

 parts of the country. We found most of 

 the localities and in several cases even 

 the exact spots where some of the human 

 remains supposed to be geologically an- 

 cient were discovered. More than this, 

 we found skeletal remains besides other 

 objects relating to the subject in the same 

 places and under the same conditions as 

 those previously reported as ancient, and 

 elsewhere collected others that threw 

 much needed light on some of the im- 

 portant points involved. Several thousands 

 worked stones bearing on the supposedly 

 ancient cultures were discovered in un- 

 disturbed positions; and many samples of 

 fossil bones and shells, as well as of
