458 W. Topley — European Geological Surveys. 



Of tlie sheets on the 1 : 50,000 scale (Ser. A, a) about 83 are 

 published ; these are numbered in the order of publication, irrespec- 

 tive of their relative positions. Each sheet is accompanied by a 

 descriptive ' Beskrifningar.' The prices, for map and description, 

 are 2 kroner for the full sheets ; 1, or 1\ kroner for the coast sheets 

 (kroner = Is. l^d.). 



_ Of the sheets on the scale of 1 : 200,000 (Ser. A, b) ten are pub- 

 lished, each with ' Beskrifningar,' price 1^ kroner. 



All the maps give the distribution of the superficial deposits, but 

 a few are published with special reference to these and to agriculture. 

 That of the environs of Skottorp, scale 1 : 4000, shows by signs the 

 nature and composition of the soil in great detail. There are also 

 some special maps referring to mining, etc. ; these extra maps are 

 in Ser. B. 



A general map of Southern Sweden (south of lat. 59° 45'), on the 

 scale of 1 : 1,000,000, will be published with a description during 

 this year (1884). 



In addition to the explanations of the maps, there are memoirs in 

 Ser. C (' Afhandlingar och uppsatsen ') in 8vo. or 4to., with or with- 

 out plates or atlas. Eighty of these are published, dating from 1863, 

 at various prices up to 8 kronei*. They refer to palseontology, 

 stratigraphy, petrology, economic and theoretical geology ; most are 

 in Swedish, but a few are in French, German, or English. 



A map of the iron district of Central Sweden, though not an 

 official publication of the Survey, should be mentioned here. This 

 is prepared, by A. E. Tornebohm, for the Board of Swedish Iron- 

 masters (Jernkontoret). It is in nine sheets (1879-82) ; each, with 

 description, price 4 kroner. Its title is ' Geologisk Ofversigtskarta 

 ofver Mellersta Sveriges Bergslag ' ; the scale is 1 : 250,000. 



Another similar publication, also by Tornebohm, is ' Geologisk 

 atlas ofver Dannemora grufvor,' in 17 sheets, with description, 1878. 



All the publications referred to are issued at Stockholm. 



Switzerland. — Beitrdge zur Geologischen Karte der Schweiz 

 (Materianx pour la Carte Geologique de la Suisse) (Berne). 



The present organization dates from 1859, when the Federal 

 Council offered to the Swiss Natural History Society a grant in aid 

 of colouring geologically the topographical map ('Carte Dufour'). 

 A geological commission of five members was then formed, with 

 Bernard Studer as President. 



The map is in 25 sheets ; three of the corner sheets are for title, 

 index, etc. Eighteen sheets are published, those not vet issued being 

 XIIL, XIV., and XVIII., all in Central Switzerland"! 



The scale is 1 : 100,000; the meridian is Paris, 2° 20' E. of 

 Greenwich. 



The text, chiefly in German, but partly in French and Italian 

 according to the locality described, is contained in ' Lieferungen ' 

 1-28, dating from 1862. Some of these describe one or more sheets 

 of the map ; others describe special districts, with maps on the scale 

 of 1 : 50,000 or 1 : 25,000. 



A general map, ' Carte Geol. de la Suisse,' was published by B.
