The likeness between things and beings, as well as between beast and birds and man, can tell us a great deal about the secret of their nature. The sciences of phrenology and physiognomy were discovered not only by examining the lives of men of various features, but chiefly by studying the similarity that exists between them and animals. For instance, a man having the features of a tiger will have a dominant nature, coupled with courage and cruelty. A man with a face resembling a horse is by nature subservient; a man with a face like a dog will have a pugnacious tendency, while a mouse-like face shows timidity.
