Interpretation of x-ray diffraction patterns of the fiber type has been developed to a great extent and used in determining orientations of individual crystals to some preferred axis in a crystal aggregate. These interpretations have a wide field of application. Ordinarily this would be divided into natural fibers and synthetic fibers. If we should follow astbury in his consideration of all molecules as fibers of varying dimensions, this field of application becomes almost all-inclusive, and suggests new divisions. The discussion here however, will be held within the ordinary divisions of natural and synthetic fiver structure in reference to applications. The patterns referred to as fiber patterns are those which are characteristic of the orientations of a needle or thread-like crystals or of specific atom planes to what is known as the fiber axis.
