Letter describing geological observations during a visit to Rome, 

 Naples, I. of Procida, Sicily, and the Lipari Islands. Describes an un- 

 favourable ascent of Etna. Mentions the occurrence of an augitic rock 

 in Lipari and Yulcano ; the b<tsic rocks here seem to be older than 

 the acid rocks, the latter enclosing frjigraents of the former. F. W. K.

An endeavour to systematize the lines of fissure accompanying 

 volcanic phenomena in Iceland, as indicated by the position of vents, 

 open fissures, geysers and solfataras, dykes, and the trend of elevations 

 and hollows. The two most distinct lines are N.E. to S.W. and N. to S. 

 Volcanic activity is stated to have moved from E. to W., occupying 

 lines previously foimed. A table of recorded eruptions is given, by 

 which the *' Heckla line " when in action is shown to h<ive silenced all 

 others. H. M.

 Part 2 of a survey of which part 1, published in 1870, deals chiefly 

 with the younger Palaeozoic formations. In ascending order, and with 

 maximum estimated thicknesses in Norse feet (77 = 100 English feet), 

 the stratified formations are: — Basement gneiss ; Quartz rock, 1500- 

 2000ft.(Begion 1 of S. Norway) ; Trondhjem and Rciros schists, 6000ft. ; 

 Conglomerate and sandstone series, 4200ft. (Kegions 4, 5, 6); Gula 

 schists, 6000 ft. This Memoir chiefly refers to the last three. These are 

 not constant, one or another occasionally thinning or disappearing. 

 Limestones occur throughout. Fossils (of some 25 kinds, only one of 

 which is specifically deteimined) are limited to the .middle group, and 

 point most nearly to liegion 5. The strike of the formations is that 

 of the country, about N.W. and S.E. A median younger tract is 

 deeply bordered towards the coast by Basement gneiss with granite, 

 and partially bordered towards Sweden by the same gneiss and by the 

 Quartz rock. All the formations are irregularly broken through by 

 the following igneous rocks coupled according to nge (youngest first) : — 

 oligoclaso granite, protogine granite ; greenstone, gabbro ; grey
