to know at once, ia a general way, what has been done, and also to learn 

 of certain works which the Congress recommended and patronized, but 

 did not undertake. 



The map of Europe, colored geologically, will be issued in 49 sheets ; or 

 7 high and 7 broad. Each sheet will be 48 centimetres high and 53 cm. 

 broad. The whole map will form a rectangle of 3.36 by 3.71 metres. 

 Prof. Kiepert, of Berlin, is charged with the duty of making a topographi- 

 cal base from the very latest data. D. Reimer and Co. are the publishers. 

 930 copies are guaranteed by the Congress at 100 francs per copy, of which 

 each of the great States of Europe, to wit : Great Britain, France, Germany, 

 Austro-Hungary, Scandinavia, Italy, Spain and Russia is entitled to 100 

 copies. The remaining 100 copies are to be divided between the six small 

 States, Belgium, Holland, Denmark, Switzerland, Portugal andRoumania. 

 The other purchasers are to pay 125 francs a copy to the publishers. 

 The scale of the map is to be 1 : 1500 000. A committee is charged with 

 the duty of receiving the colored maps sent in by each country, and 

 of harmonizing them so that they will make a connected whole. This 

 committee consists of Messrs. Beyrich, Hauchecorne, Daubree, Giordano, 

 Moller, Mojsisovics, Topley and Renevier. But the Committee of Direc- 

 tion, which will really superintend this work, is composed of the first two 

 named, who are on the ground and can better look after the publishing. 

 It was proposed by the committee having in charge the adoption of a uni- 

 form system of coloration, that a greenish-gray tint be adopted for the 

 Silurian (Cambrian included). This was warmly opposed and finally the 

 section was altered so as to give the committee the discretion to adopt some 

 provisional means of distinguishing the series at the base of the Paleo- 

 zoic column, with the understanding that it should not in auy waj- pre- 

 judice the final scientific decision of these questions. The divisions to 

 be made of the Cambrian and Silurian combined will therefore be three- 

 fold, and the three divisions will be different shades of greenish-gray. 

 After the color questions were thus disposed of, M. Dewalque began the 

 more radical questions of the actual divisions themselves. The measures 

 below the Paleozoic column are to be called Archaean, and each geologist 

 is to be left free to distinguish their separate divisions by petrographic char- 

 acters, without as yet attempting to correlate them in different countries. 

 M. de Lapparent did a notable service to science here by proposing that 

 the term "Protogine" which was based upon no important or necessary 

 characteristic, be once for all abolished. This motion was unanimously 

 carried. The Silurian-Cambrian question again coming up, it was decided 

 to leave the debate on the proper coordination of the series till the meeting 

 in England, three years hence. In the meantime, the committee on the 

 map was permitted to make the divisions as well as it could, but to give 

 no names. 



It was decided to divide the Devonian into the Rhenan, the Eifelian, 

 and the Famennian. (2). That the Calceola beds should form part of 

 the Eifeli m, and fiat the upper limit of the Devonian should be drawn at
