and two of the'brbwn Chalk of Ciply are given, with these results, that 

 the mean composition of the former gives 19-75 and the latter 11-25 p. c. 

 of anhydrous phosphoric acid. A new locality for phosphatic nodules, 

 discovered by M. Lambert at Ghlin, is alluded to in a postscript ; an 

 analysis is given showing 21-82 per cent, of phosphoric acid. [Keports

This limestone, near Gratz in Styria, contains felspar, which from 

 analysis seems to be Albite ; it is 6-8 metres thick, and interbedded 

 in gneiss. E. B. T.

Fossils found above the gypsum show that it belongs to the upper 



division of the Mediterranean stage, in which it is an intercalation.

In the section are shown upper and lower primitive stratified rocks, 



amphibolite, gabbro, and greenstone, and also Silurian (Eaipas group) 



and Devonian (Gaisa group). E. E.

Tunnels or arches more or less resembling the well-known instance 

 of Torghattan, but smaller, in or near the island of Soro, are described. 

 The largest is 31 metres above the sea, and marks a former level sup- 

 posed to date somewhat prior to the gulfstream or later postglacial 

 period. The others stand nearer the water ; and all are hollowed in 

 softer schist. The holes are giants' kettles in the island of Yanna, from 

 one of which a fissure descends apparently several hundred feet. H. M.

Gives an account of the geological literature relating to the district, 

 and describes the rocks as follows : — 1. Primitive Rock, occurring gene- 

 rally in narrow strips of unknovm thickness; probably Laurentian. 

 2. TJiomso mica-slate group, 1900 metres thick : probably Old Cambrian 

 or Huronian. 3. Balsfjord slate-field, thickness unknown ; probably 

 younger Cambrian or Taconian. 4. Alten smd Kvoenaiigen group (Raipas 

 system of T. Dahll) ; probably Silurian, but perhaps Devonian. 5. Golda 

 group (Gaisa system of Dahll) ; perhaps Devonian. 6. Jurassic, occur- 

 ring only at Ajido in Yesteraalen. There are no Cretaceous or Ter-
