Abstract
THE Second International Geological Congress will be held at Bologna in September, 1881. It is proposed to award a prize of 5,000 francs for the best international scale of colours and conventional signs for the graphic representation of formations on geological maps and sections. Each scale should be accompanied by an explanatory memoir and a sufficient number of maps and sections relative to regions of different geological characters; for the memoirs the French language is recommended. The names of the competitors should be inclosed in sealed envelopes, on which should be a motto. The scales and memoirs should be addressed, before the end of May, 1881, to the President of the Committee, Signor J. Capellini, 65, Via Zainboni, Bologna.
