The doctrine of Induction here set forth is in sub stantial agreement with that developed by Dr. Bosanquet in his most philosophical book on Logic. To Dr. Bosanquet I owe a. Deep debt of gratitude for his kindness in giving me permission to make full use of his labours a permission of which it will be seen I have freely availed myself. In this portion of my work I also owe much to the works of Mr. Bradley, Sigwart, Lotze, Jevons and Whewell.
