Note 109 — Chapter I · History of the Sexual Theory.

Lazaro Spallanzani was born at Scandiano in Modena, and died at Pavia in 1799, where he was for a long time Professor of Natural History. He made researches in very various questions of natural science, and especially in animal physiology; but they seem to have been conducted with the same want of care and deliberation which appears in his experiments on sexuality in plants. A long article in the ‘Biographie Universelle’ gives a detailed account of his scientific labours.
