Pavel Passalsky (1870-1900) was appointed observer at the Meteorological Observatory of the University of Odessa in 1894, where he devoted himself primarily to magnetic measurements; this posthumous work, prefaced by Boris Weinberg, is the result.

The city extends over some fifty kilometres along iron ore deposits, making it the longest city in Europe.
