Domenico Guglielmini (1655-1710) was an Italian mathematician. In 1686 he was nominated “general intendant of the waters” in the Bologna area. Thanks to the fame he gained through hydraulic works, in 1694 Gugliemini obtained the chair in hydrometry at the University of Bologna. This book, first published in 1697, is considered his masterpiece. It discusses the nature of rivers and their parts, the motion of water, estuaries and confluents, riverbanks, and the kind of materials carried by rivers. The use of Italian (instead of Latin) demonstrates Guglielmini's intention to circulate the text among a relatively wide audience, which could appreciate the public usefulness of his researches. What is presented here is the second edition of the treatise, with the annotations of Eustachio Manfredi, who was Gugliemini's successor in the office of “general intendant of the waters” in Bologna.

As head of the Breeding Station of the Belgian Farmers' Union, of the university Laboratory for Applied Genetics and of the Flemish department of the General Inspection Service for Seeds and Seeds, Dumon was an expert in the extraction, propagation and breeding of seeds. His remarkable didactic collection includes dozens of test tubes, sachets and aspirin tubes filled with colorful seeds.
