Abstract
IN our letter in NATURE of November 161, we described a new technique for obtaining X-ray powder patterns using flat specimens. Dr. Brentano maintains2 that the method is, in its principles, the same as his focusing method. Dr. Brentano has always used beams diverging from a line source of X-rays, and it follows that for great source to specimen distances the diffracted beams are focused at glancing angle. This is the only resemblance between his method and ours.
