hrdliCka] skeletal REMAINS OF EARLY MAN 205 



On page 65 of the above-mentioned work we read the follo\ving 

 about the depth of the bed of the Arroyo de Frias : 



''The Arroyo de Frias runs, as do nearly all the small streams in 

 the Bonaerean flats, through a nearly liorizontal plain of uniform 

 geologic constitution, and its channel varies in depth from 2 m. to 

 2 m. 30 cm. . . . 



"Vestiges of the activities of ancient man and human bones are 

 encountered in the penultimate layer f^l at the level of the water of 

 the Arroyo and lower in the last la3^er up to 1 m. below the bed of 

 the stream. 



"In 1870 I extracted at this point, on the left margin of the Arroyo, 

 a human skull accompanied by a considerable part of the skeleton, 

 and many bones of extinct animals. I attached but little importance 

 to this find, and the skull was carried to Europe by a collector and 

 given to the Museo Civico of ^lilan, where it is conserved without 

 having as yet been described. 



"Three years afterward, in September, 1873, I found at the same 

 point additional human remains." Then follows a brief account, 

 differing in a few particulars from those given above, of the find of 

 the human bones under consideration in this chapter. Besides the 

 bones of animals, Ameghino mentions again, as having been found 

 with the human bones, "a considerable quantity of fragments of the 

 shells of ostrich eggs." 



On page 83 of the same work, finall}', after giving some vague recol- 

 lections concerning the skull found by him at the Arroyo de Frias in 

 1870, Ameghino adds: "Later on, as I have already mentioned, I 

 gathered at the same place (en el mismo punto) other fragments, 

 which I suppose belonged to the same individual." ^ 



Lehmann-Nitsche, in his work on the human remains from the 

 Pampean formation, deals with both of the Arroyo de Frias finds. ^ 



As to the human remains collected by Ameghino in 1870 and taken 

 to the ^luseo Civico of Milan, we learn that in 1890 Santiago Roth 

 visited that institution in order to secure all the information possible 

 on the subject, but no one was found who knew anything of the 

 specimens, and an Italian, Morselli, who looked for them in the 

 museum did not discover any trace of them. 



The bones belonging to the second find, that of 1873,* were sub- 

 jected anew to minute examination by Lehmann-Nitsche and 

 Leboucq, of Gand. The results of these studies are that, while the

2 No details are given as to the position of the skull, though such data would be, it seems, of much impor- 

 tance, and, curiously, no mention of this first find is made in the lengthy report on that of 1873 (La 

 antigiiedad, etc., n, 18S1, p. 483 et seq.).

■• An erroneous statement is found on p. 215 and again on p. 244 of the Nouvelles recherches, etc. The 

 text reads that the bones were found more than 2 meters below the level of the water in the arroyo; this 

 (Joes not correspond to any statement by Ameghino.
