hand, but in the broken quartzite from Monte Hermoso there is 

 absolutely notliing similar. 



"On the other hand, these broken quartzites, however rustic they 

 may appear, are surely the work of man or liis precursor, for there 

 can not be opposed to them the objections which are being made to 

 the eoliths. In tliis case there can be no question of pressure by the 

 rocks, of shocks produced by stones driven by water or due to fallmg 

 stones, because, I repeat, they are loose in the sand, and are all 

 separated one from the other. 



"It is my duty to say that I have seen Doctor Hrdli6ka gather 

 similar objects, but I do not know how he interprets them nor have 

 I asked him. I declare myself, therefore, solely responsible for the 

 significance which I give to the material in question." 



Criticisms hy F. F. Outes. — Shortly after the first announcement 

 by Amegliino of his discovery of the new "split-stone industry,"^ 

 F. F. Outes published an article ^ in wliich he announced numerous 

 finds of similar specimens in the same and also in other localities 

 along the coast. He reported in at least one instance the association 

 of such stone objects as are described by Professor Amegliino, with 

 implements, rejects, etc., of quartzite, and he opposed both the 

 geologic antiquity wliich has been attributed to the worked stones as 

 well as the supposed great primitiveness of the workmanship. The 

 principal features of the communication are cited below. 



Visiting the localities of the higlily interesting new stone industry, 

 says Outes: "I was easily able to gather 187 different specimens 

 belonging to that industry, not only in the locality indicated to me 

 wdtli notable exactness by the distinguished geologist and traveler, 

 Don Carlos Amegliino, but in four others similarly situated along the 

 coast. 



"The barranca wliich constitutes the left boundary of the mouth 

 of the Arroyo Corrientes is formed in the larger part of Pampean 

 loess and of eolic deposit of the present era, on both of wliich denu- 

 dation has acted extensively. 



"On the surface, distributed irregularly, isolated, or in small 

 gullies, but never covered by either earth or sand, I have found 91 

 objects belonging to the primitive industry referred to by Professor 

 Amegliino. 



"I gathered 56 other pieces at Punta Porvenir, a little spur of 

 quartzite rounded b}' the beach and nearly submerged when the waters 

 are very high. Over a large part of this point, in its folds, is found a 

 veneer of eohc deposit, identical in composition with that of the 

 mouth of the Arroyo Corrientes and equally as much denuded. 



1 The terms "split" and "broken" as applied to these industries should not be confused.
