Abstract
THE term “crust” is frequently used in dealing with the constitution of the earth, but is seldom defined. It is a convenient scientific term to apply to the earth's outermost shell, the only portion of which geologists have much positive knowledge, and if it is put to scientific use, it should be defined, although a definition of it may involve some hypothesis as to the physical condition of the earth's interior.
