1901. As the reader will start reading this book with an inevitable bias against it, Mr. Miles would ask him to be so kind as to listen to a few words first. He assures, to begin with, that this book is not a mere collection of systems: systems are included, it is true, and among these there are systems which can be, and frequently have been, most shamefully misused. The careful reader will notice that these systems come in the second places in the book; moreover he will notice that they are not all necessarily short cuts for the lazy; and he will candidly admit that even short cuts are not always an unmitigated curse. Contents: value of memory; helps to memory, apart from memory systems: in detail, with further examples; memory systems: in detail with further examples; systems applied to various subjects; practice and other helps; raisons d'etre, and the advantages of good methods and systems when rightly used; objections anticipated and answered: with a reference to some useful books.
