with these knives, just above the ears, and the whole scalp jerked 
off. These were then rapidly smoked over a fire kindled in a 
small round hole, and borne off in triumph towards home, 
together with the arms and legs, suspended upon spears.” Upon 
arriving at home they suspended these mangled limbs and 
trophies and danced around them in honor of their victory. 
Again, in arranging the Wilkes collection for the National Mu- 
seum, I was struck with the great number of spear-points made 
of human bones. The question occurred to me then, and has 
been revived by Prof. Wyman, whether any magical effect would 
be attributed to spear-points made of the bones of a brave enemy. 
The absence of pointed bone in Omori would, of course, exclude 
the spear-point or implement theory. In conclusion, we consider 
Prof. Morse’s memoir one of the most important contributions to 
archeology for the year 1870. 
Numbers 3, 4 and 5 of Materiaux contain the following papers 
of interest to general students: Les pierres a bassin et les rochers 
a écuelles dans la Lozère, by G. de Malafosse; A Review of Evans’ 
Ancient Stone Implement in Great Britain; Palazo-ethnological 
bibliography for the year 1878, by L. Pigorini; The Teneviéres 
of the Swiss lakes, by Dr. Forel; The latest archeological pub- 
lications in the North, the Archeological Society of Finland, by 
- Beauvois; Upon the origin of domestic animals, by G. De 
Mortilet; New anthropological publications in the German 
language ; Study upon ring-money and its use among the Ger- 
mans, hy Dr. Much. The article by Dr. Forel upon the Zene-. 
veres of the Swiss lakes is a very, important one indeed. In M 
esor’s classic work upon the palafittes of Lake Neuchatel, the 
author describes certain little submerged stone mounds, formed, 
apparently, by heaping rocks around the bases of piles. When 
_ the lakes subside, the mounds form true islets. Dr. Forel’s arti- 
cle is to show that many of these are of geological formation, 
prog the natural consequence of a talus forming at the foot of a 
uff. 
GEOLOGY AND PALÆONTOLOGY. 
THICKNESS OF THE Ick SHEET ON ITS SOUTHERN EDGE.—At the 
Saratoga meeting of the American Association for the Advance 
of Science, Professor J. C. Smock spoke of the surface limits of 
thickness of the Continental glacier in New Jersey. The exist- 
ence of a great terminal moraine and a southern limit to the 
glacial drift in New Jersey and the adjacent States, were pointed 
out to the author in 1876, by Professor Geo. H. Cook. In that — 
year the southern limit of the glacial drift was traced across the 
State from South Amboy to a point on the Delaware river, near 
Belvidere. Details were given of further investigations in tracing 
this line. The paper considered two questions:—What was the 
thickness of the ice-sheet along its southern margin; and what
