WERE TAKEN, 
water-level ; 2, is a thin layer of gravel as found in excavating on 
the right side of the stream, and which was material deposited by. 
the stream which it had washed from more elevated portions of 
its bed; number 3 is a layer of vegetable mold 10 cm. in thick- 
ness, which contains numerous bones of domestic animals intro- 
duced into the country since its occupation by Europeans; number 
4 is a stratum 40cm. in thickness,and contains the bones of animals 
indigenous to the country, and number 5 is a very clayey stratum 
20 cm. in thickness, and contains the bones of extinct species of 
animals, but in a poor state of preservation ; number 6 is a marly 
layer 30 cm. in thickness, in which the bones of the great 
extinct mammals, Mylodon, Glyptodon, etc., are found; number 7 
is 60 cm. in thickness, is not nearly so marly as the preceding, 
and also contains remains of extinct animals; number 8 is 55 
cm. in thickness, of a reddish color, and is composed exclusively 
of fine sand and clay mixed together. The stratum, number 9, 
which is more than 1.5 m. in thickness, is only distinguished from 
the preceding in that it contains a larger proportion of clay. In 
this layer of pampean soil, at the base of the excavation indicated 
in-the diagram, and at a lower level than the bed of the stream, 
there were human bones discovered, together with rudely-shape 
flints, apparently used in extracting the marrow from bones, a 
perforated femur of Eutatus, bones with incised and some with 
radiate markings and striz, fragments of burnt bones, fragments 
of burnt or baked earth and a great quantity of charred vegetable 
substances. In the same deposit, mingled with the objects men- 
tioned, there were also a great many bones of animals found, 
which indicated the following species: 
1. Hoplophorus ornatus (Owen). A great part of the carapace 
id some bones. 
2. /Hoplophorus sp. indet. A portion of the carapace and other 
ones. ; 
3. Skull and a large portion of the skeleton of Eutatus of a 
- hew species. 
= 4., Portion of the carapace and bones of a very small armadillo 
of an undetermined species.
