Experiments Concerning Animal Gerneration

…Exercitationes de Generatione Animalium (Exercises on the Generation of Animals), it is believed that Harvey attempted to take his own life with laudanum (an alcoholic tincture of opium). However, this attempt failed. On June 3, 1657, at the age of 79, he died of a stroke.

His second great book, Exercitationes de Generatione Animalium (“Experiments Concerning Animal Generation”), published in 1651, laid the foundation of modern embryology.
