Doughty — Jostedal-brce Glaciers in Norway. 



it were, cut up into immense plateaux by tlie intersecting valleys. 

 On as many of these plateaux as reach, the snow line, the snow, 

 which is constantly accumulating, becomes transformed into a com- 

 pact icy mass, traversed by crevasses, and by its weight the entire 

 mass gradually finds its way to lower levels, both squeezing out 

 its surplus down the valleys as ordinary glacier-streams, and dis- 

 charging from the cKffs in shoots of ice -blocks. 



Mr, Doughty gives accounts of the several glaciers marked on 

 the small plan of Jostedal, with measurements made by him with 

 a theodolite, in July and August, 1864 ; and his observations tend to 

 prove the identity of the glacier streams of Norway with those of 

 the Alps. He makes some remarks on the nature of the channels of 

 the ice-streams, and on the moraines, and states that, as specimens 

 of the contemporaneous faxma and flora are being entombed every day 

 in the glacial accumulations, and man occasionally among the rest, 

 very early traces of the human race may be looked for in the deposits 

 of the older glaciers, if man were then in existence and inhabited 

 those parts of the globe. H. B. W. 



IV. — The Flint Implements of Spiennes in Hainaut. 



By Professor C. Malaise, Docteur en sciences naturelles, etc. 

 [Bullet, de l'Acad. Eot. be Belgiquf, 2me. serie, tome xxi., 1866.] 



IN this communication Prof. Malaise records the discovery of a 

 number of worked flints, below the loess (the ' Hesbayan mud ' 

 of M. Dumont), near the village of Spiennes, south-east of Mons ; 

 they are very rudely shaped, and belong to the " Stone age." 



The loess caps two plateaux between which the river Trouille 

 flows before passing Spiennes ; it has a varied composition, often 

 argillaceous and of a browoiish-yellow colour in the upper part, and 

 calcareous, of a greyer colour, with calcareous concretions containing 

 fresh-water shells, deeper down. Worked flints were obtained in 

 situ, just below this deposit of loess, but they were also found scat- 

 tered over the surface of the plateaux ; their position, and the geo- 

 logical structure of the country will be seen from the accompanying 

 section by Prof. Malaise.
