Engelmann, Bibl. mech.-techn., S. 106. - A rare first edition of a work on the rope-drilling method adopted from China and its application in the construction of artesian wells. Frommann combines a description of Chinese drilling techniques with his own practical experience, producing one of the earliest monographic treatises on the subject in the German-speaking world.
