GEOLOGY. 
Eozoon AND irs Autres IN Later Formation. —I have for some 
time been pursuing investigations of Primordial and Silurian fos- 
sils akin to Eozoén either in structure or mode of preservation. 
When these investigations are completed, I hope to show that 
Eozoon has several foraminiferal successors in the older palzozoic 
rocks of Canada, and that fossils of various kinds occur in those 
rocks infiltrated with mineral matter in a manner not dissimilar 
from that observed in the Laurentian Eozoon.—J. W. Dawson, in 
Nature. 
ANTHROPOLOGY. 
Tue [ĪNHABITANTS or THE NILE WATERSHED. — Perhaps the most 
important advance which has been made in geographical discovery 
during the past year has been the exploration of a large portion 
of Central Africa, lying to the northwestward of the great equa- 
torial lakes, by Dr. Schweinfurth, already known through his bo- 
tanical studies in the lower Nile valley, the first practised traveller 
who has penetrated far into this region. The ruling tribe of the 
inhabitants of the Nile watershed here; is that of the Niam-Niams, 
who are described by the Marquis Antinori as men of powerful 
form and stately carriage, bronze-colored skin, and long sleek 
hair. On crossing the water-parting into a fertile country, where 
the oil-palm gives a new character to the landscape, Dr. BaT 
furth came upon a race differing from these in every resp ' 
Abanga and Monbuttu of the inner watershed are peep a 
by the lighter color of their skin, and their blonde and frizzled 
hair is worn by both sexes in a high chignon. Though inhabiting 
a richer land than the Niam-Niams, and in advance of them in 
agriculture, and the arts, cultivating the banana and other fruits, 
trading in copper, and forging weapons in iron, the Monbuttu 
rank far beneath them in the scale of humanity, since they indulge 
in cannibalism to an extent which appears to be unparalleled on 
the globe, a practice in no way explicable here by necessity, since 
the land abounds in game of all kinds. To the south of the Mon- 
buttu is a dwarf race named Acka or Ticki-Ticki; the average 
height of the men of this tribe is five feet, but many do not reach 
this measure. — The Academy.
