Certain ofthem have, like the migratory birds, two or three domains that theyoccupy successively. To go from one to another they emigrate in amass, and follow routes of which the traces are subject to the ruleswe have set forth for the migration of birds. The relentless warthat fishermen with a knowledge of their habits make upon themhas never caused them to change their itinerary. Our theory of orientation seems, therefore, applicable to animalsof all kinds. It permits us to arrange and explain in a very satis-factory manner a number of facts observed and known for a longtime.
