 read before the Industrial and Scientific Society of that State, that besides its riches of coal and iron, the State has clays of quality suitable for the manufacture of every kind of brick and stoneware. They are not yet developed, for want of skilled and experienced workmen, and because the world is not acquainted with their qualities. The different clays and their location are fully described in the paper.

Arago prize of the French Academy of Sciences has been awarded to Prof. Barnard and Prof. Asaph Hall.

Geological and Natural History Survey of Minnesota has begun the publication of bulletins embodying from time to time such discoveries as may be made or scientific contributions presented as they occur, without waiting for the slower publication of the formal reports. The first of the series of botanical studies, Bulletin No. 9, contains five papers of interest in that branch of the survey. The Bulletin will be continued in occasional parts till a volume is completed,
