This survey was commenced in iH^'u (as Conunissao Geol. do Portugal). 

 It was reorganised with the existing title in IHGU, under the direction of 

 Carlos Ribeiro ; he was succeeded, in 1883, by J. F. N. Delgado. 



The work is now done on the scale of 1 : lUO,(»()U; with occasional 

 enlargements to double this scale. There are contours at intervals of 

 25 metres. Tho map will be in 37 sheets, longitude reckoned from 

 Lisbon, i>° 9' W, of Greenwich. The topogrn])hical map is not yet 

 complete, and none of the sheets are published with the geology. 



Several memoirs have been published, dating from 180;) ; and also 

 a general maj) — ' Carta Geologica de Portugal,' by C. Ribeiro and 

 J. F. N. Delgado, scale 1 : nou.UUU ; 187G (now out of print).

The publications of this survey date from 1870 ; tho dii-ector is W. 

 Hauchecorne. 



The map — ' Geologischo Special-Karte von Preussen und den Thiirin- 

 gischen Staaten ' is on the scale of 1 .' 25,000 ; with hill-shading, and con- 

 tours at intervals of 5 metres. 



It is divided into 88 ' Grad-Abtlieilungen ; ' each subdivided into CO 

 ' Bliittern,' excepting on the frontier and sea-board, where some sheets arc 

 absent. Each complete ' Grad-Abtheilung ' contains exactly 1° of long, 

 and 1° of lat. ; each ' Blatt ' contains 10' of long, and G' of hit. ; the sheets 

 ai'e thei'cfore not quite rectangular. The longitude is reckoned from 

 Ferro, 18° !»' W. of Greenwich. 



The publication takes place in ' Lieferungen,' each containing from 

 three io nine maps of the same district, though not always in the same 

 • Grad-Abtheilung.' The ' Lieferungen ' vary in price according to the 

 number of maps included, averaging 2 marks per map with its ' Ei-liiu- 

 terung.' The maps near Berlin are especially agricultural, minute 

 variations of soil being indicated by signs ; these form a special set of 

 maps, in 27 sheets. In tho coal districts two editions are issued, one 

 showing the edges of the coal-seams beneath the newer rocks. 



' The first part of the serial publication of this Hurve}' has just been issued — 

 ' Commtinica^iicK da Si'c<;ao dos Trahalhos Geoloijicos de Portugal,' torn. 1, fasc. 1, 1885; 

 8vo. Lisbon. Some of the papers therein contained had been previously printed.
