1887. Otherwise known as the science of representation. An abstract of the theories and diagrams of B.W. Betts. Benjamin Betts was educated as an architect, but his mind turned toward the study of internal truth, and he resolved to quit his intended career in order to think out his philosophy of life. The present writer, seeing that no one more capable seemed likely to assist Mr. Betts in preparing his work for publication, undertook to make an abstract of it.
