QUESTIONS ON NATURAL SCIENCE

[Illustration]
This volume is an aid to the study of the "Harmonic Series." While it
commands the attention of the casual reader of the Text Books, it is
intended more especially for those who contemplate a closer relationship
with the philosophy and for those who _have been admitted to
studentship_.

To the aspiring student it opens up the entire Harmonic Philosophy in a
manner that invites and facilitates the most intense interest,
satisfaction and progress.

355 pages, 20 chapters, and 3,857 carefully formulated questions, all of
which are _authoratatively_ answered in the Text Books. Three-quarter
leather, price $2.00.

THE SPIRIT OF THE WORK

[Illustration]
_By TK._

These beautiful and inspiring essays by the Beloved Elder Brother are now
printed in book form, for ready reference, and will prove to be quite as
interesting and helpful to the beginner in Natural Science, as they are
useful to instructors and regularly admitted students.

They unfold in simple language a wealth of spiritual light that leads at
once to a most searching soul--analysis and readjustment of the entire
intelligence to the Constructive Principle in Nature. Every page breathes
the very inmost meaning and spirit of the educational work of the Great
School. If you are in earnest this book will help you. 331 pages, cloth,
price $1.00.
