The publications comprise the * BoUettino,' (in 8vo.), dating from 1870, 

 of which fourteen volnmes are published ; and ' Alemorio ' (in fol.), dating 

 from 1H71, of which two volumes are published. These volumes contain 

 numerous maps, on vui'ions scales, and plates of fossils. Many of tho 

 authors of papers here published are not connected with the survey; but, 

 as a Geologicnl Society was founded for Italy in iHHl, tho survey 

 publications will prol)al)ly in future be more purely ollicial. 



Several semi-otliciid maps aro issued. Three are by Prof Capellini, a 

 member of the Ctunllato, These are- — tho Holngnoso Apennines ; Leghorn 

 (each 1 : 100,000) ; Gulf of Spozia (1 : 50,000).

An official survey of this country was made by ^'^. C. H. Staring, and 

 published (' (ieologische Kaart van Nederland ') at Haarlem, in "ll small 

 sheets; iH.'xS C)/ with explanation. The .scale is 1:200,000; the 

 meridian Amsterdam, A° hW E. of Greenwich. The map shows 13 

 varieties of alluvium, 8 of diluvium, 10 of Pliocene — Eocene, with other 

 rocks down to Devonian. 



Another map (V not official) has been published by Krnijder, in six 

 sheets, 1880.

The geological investigation of this country is in two parts. That of 

 Southern Norway, under tho direction of Th. Kjcrulf, dates from 1858 ; 

 that of Northern Norway, under the direction of 1\ Dahll, dates from 

 1860, and was completed in 1878. For the former there aro two assist- 

 ant.s, with extra help during tho summer. 



The surveying work is done on various scales — for the most part 

 1 : 100,000, but some 20/, 50/, and 200,000. For ihe last the meridian 

 is Ferro ; for the others it is Christiania, 10° 43' E. of Greenwich. 



The published map of Southern Norway, in rectangular sheets, ia 

 on the scale 1 : 100,000, with contours at 100 feet (1 Norwegian foot=: 

 12.35 English inches). Seventeen sheets aro published, dating from 

 187G. These are grouped as follows : Trondhjem and distinct, 8 sheets ; 

 Bergen, 2 ; Hamar, 2 ; Christiania and Fredrickstadt, 5. Each sheet is 

 priced kr. 1-60 (1 kr. = Is. 1^:-/.). 



A general map of part of Southern Norway (Diocese of Christiania, 

 Hamar, and Christiansand) was published in 185G-65, by Th. Kjerulf and 

 T. Dahll ; scale 1 '. 400,000 ; 10 sheets ; with explanatory pamphlet in 

 French ; in this the meridian is Ferro. 



A general description of Southern Norway with atlas and map 

 ('Geologiske Oversigtskarte,' 1:1,000,000), was published by Th. 

 Kjerulf in 1879. (German translation, by Dr. A. Gurlt, in 1880). A
