 Describes curious sandpipes, by some considered as having been 

 excavated from below — as being, in fact, natural artesian wells.

 pp. 95, 96, 140. ^ 



The Sperenberg boring is 4172 feet deep in Triassic beds. The upper 

 part is through Gypsum, passing down into Anhydrite. At 291 feet 

 pure rock-salt was met with, in which the boring continued to the 

 bottom [see Geological Recokd for 1874, pp. 105, 162]. "W. T.

Describes the occurrence of Apatite) in upwards of 20 Norwegian 

 localities. In all cases the mineral occurs in veins, which pass in- 

 differently through eruptive and sedimentary rocks. Those in Gabbro 

 are described first ; then those in other rocks ; lastly, each mineral is 

 described in detail. The authors refer the veins to an eruptive origin, 

 and seek to explain the regular structure of the veinstone ; near the 

 walls the minerals are often finely granular, but in the centre of the 

 vein crystallized, and the crj^stals are often curved. They conclude 

 that the eruption of the veins carrying Apatite was contemporaneous 

 with or immediately after the outburst of the Gabbro. F. W. R.

 Applies to this district of the Valais the views published by M. Mois-

 specially the mechanical characters of the veins of the region. There
