fact, viz. : tliat a closely defined line separated tfie parts in which the earth- 
quake was felt from those in which no shock was experienced. This line 
corresponds exactly to the strike of the nietamorphic limestone. — Vide

Remains of Early Man in Relyian Cavei'ns. — In a memoir laid before the 
Royal Academy of Belgium, M. Dupont has given a description of the bones 
and carved and sculptured objects discovered by him in the cavern of the 
Lesse known by the name of Trou-Magryte. The bones found were those 
of Elephas primigenius ) Rhinoceros tichoi'imus, Cei'us elaphuSy ox, chamois, 
marmot, various species of Ursus, Hycena speloea ; Felis Engiholiensis ) the 
wolf, the fox, and the reindeer. — Vide E Institut, February 5. 
The Erratic Phenomena of the Valley of Argelez and the Conjluent Valley 
is the title of a paper read before the Academie des Sciences, by MM. Ch. 
Martins and Ed. Collomb. The authors attribute the character of the 
valleys to the existence of ancient glaciers. In this they differ from M. Elie 
de Beaumont. The paper is full of interest to the geologist. — Vide Comptes

A Fossil Pari'oty which was found in the island of Rodrigues, has been 
carefully examined by M. Milne Edwards, who states that the species 
resembles the Psittacns Erythacus of West Africa, the Poiocephalus robustus 
of the Cape of Good Hope, and the Mascarinus vasa of Madagascar. It has, 
however, structural peculiarities which separate it from them. M. Milne 
Edwards forms it into a new species. 
British Fossil Cycads. — Mr. W. Carruthers, being engaged in investigating 
the structure of these fossils, would be obliged for information respecting 
specimens from any British locality which would enable him better to 
prosecute his inquiries. He reserves the examination of the foliage to a 
future period, confining himself for the present to the stems and fruits. 
Communications may be addressed to him at the British Museum. 
Mammalian Remains at Ilford . — Mr. A. Brady has at much expense saved 
from destruction some fine remains recently discovered by workmen at Hill’s 
Pit, Ilford. The remains included two fine pairs of horn- cores of Bos pri- 
migeniuSy a fine antler of Cervus Elaphus (with eight prongs), and a grand 
tusk of Elephas prhnigenius, measuring nine feet six inches in length. Large 
numbers of loose limb-bones and vertebrae of Bosy and bones of Ui'sus and 
EquuSy were also obtained. 
British Graptolites. — Those who wish to study this group of fossil Hydrozoa 
in all their relations should consult Mr. Carruthers’ admirable memoirs in 
the Geological Magazine (February and March). The author has taken up 
the terminology given in Huxley’s monograph on the Oceanic Hydrozoa 
(Ray Society), and has applied it to the fossil Graptolites, and thus he 
has given a philosophical character to his descriptions which cannot fail to 
render his investigations of great interest to both the geologist and the student 
of Natural History. 
A new Section of Cambrian Rochs at Llanberis has been communicated to 
the Geological Magazine for March, by Mr. George Maw. He especially 
describes the Welsh greenstones, and publishes the result of a determination 
of their chemical constitution made at his request by Professor Voelcker. 
The following are the results of this analysis : —
