Aristotle - On the Parts of Animals

On the Parts of Animals (Greek: ΠΕΡΙ ΖΩΩΝ ΜΟΡΙΩΝ; Latin: De Partibus Animalium) by Aristotle (ΑΡΙΣΤΟΤΕΛΗΣ). The first book asks whether animals were designed or came into existence by chance. The remaining three books focus on particular examples of various animals and the functions of their organs. The translator William Ogle, who was both a medical doctor and classicist, presented Charles Darwin with a copy of this translation. (Adapted from Wikipedia by Geoffrey Edwards)
