1038 General Notes. [ December, 
Maudsley describes the ruins of a town which he believes to have 
been the’ Chacujal of Cortez. Here the houses are of the same 
long and narrow form but were roofed with thatch, and are of in- 
ferior Construction. 
American News—Up to August 27, fifty-three sheets of the 
general topographical atlas of the United States have been pub- 
lished. The forces of the Geological Survey are at work in Massa- 
chusetts, Northern Virginia, Central Arizona, and in the gold 
region around, Oreville. Two topographic parties and one 
hydrographic party are, according to “Science,” at work on the 
re-survey of San Francisco bay. The Coast Survey is also at 
work on the transcontinental arc, with telegraphic longitude 
parties at Salt lake and Ogden. 
EUROPE AND Asta—Lake Leman.—From a paper read by Pro- 
fessor Forel before the Association of Swiss Geographical 
Societies, it appears that there are two parts in Lake Leman, one 
small and shallow, the other large, deep and Alpine in its char- 
acter. The two are separated by the Yvoise bank or bar, which 
is really a glacial moraine, as shown by the flints dredged up. 
Knowledge of the central portion of the lake is still very incom- 
plete. The fragments of rock, sometimes brought up from a depth 
of sixty-one metres, are covered with moss of a beautiful green— 
a fact that seems to show that light penetrates to that depth. It 
has been discovered that the river Rhone flows in a sub-lacustrine 
_Tavine. 
The Pamir-—The last issue of the Izvestia of the Russian 
Geographical Society contains a map of the upper course of the 
Amu-Daria between the 36th and 41st degrees of latitude, and the 
66th and 76th degrees of longitude. The whole of the Pamir ap- 
pears on this map according to the recent surveys and barometric 
levelings of the Pamir expedition, while a number of other sur- 
veys are taken into account. i 
M. Krendowsky (Memoirs Kharkuff Soc. of Naturalists) de- 
votes a paper to the estuaries of the Bug, Dnieper, and other 
smaller ones in the neighborhood of Kherson and Odessa. He 
gives the character and geological history of these estuaries, 
which are now shut off from the sea by their sand-bars, and have 
come mere elongated salt lakes. ; 
The Geographical and Statistical Dictionary of the Russia? 
Empire, commenced more than twenty years ago, is just eri 
pleted. Its great value, says Nature, is in the excellent geograph” 
ical descriptions of the localities treated, including not only ca 
separate government of Russia, Siberia, Turkestan and the ae 
casus, but of the seas that border Russia, and of their islands. 4
