If the women but have little virtue, the jealousy of their husbands is extreme, and their revenge deadly and almost certain. A few inches of cold steel have been the punishment of many an unwary man, who has been guilty, perhaps, of nothing more than indiscretion. The difficulties of the attempt [to copulate with a married woman] are numerous, and the consequences of discovery fatal, in the better classes. With the unmarried women, too, great watchfulness is used. The main object of the parents is to marry their daughters well, and to this a fair name is necessary. The sharp eyes of a duena, and the ready weapons to a father or brother, are a protection which the characters of most of them — men and women — render by no means useless; for the very men who would lay down their lives to avenge the dishonor of their own family would risk the same lives to complete the dishonor of another.
