The Potsdam Meteorological and Magentic Observatories ¹

Abstract

THE volume referred to below gives a lucid description of the observatories at Potsdam, compiled by Profs. Suring and Schmidt, who are in charge respectively of the meteorological and magnetic departments. A preface by Prof. Hellmann, the director of the Royal Prussian Meteorological Institute, to which the observatories be-long, states that the book is primarily intended for the benefit of those studying at or visiting the observatories, the number of visitors being now large. The text describes the buildings and instruments, while reference is made in footnotes to many researches associated with the place. Thirty-one figures supplement the descriptions of buildings and instruments in the text, and a plate gives a ground-plan of the whole site.
