The article presents information on examination of papers in questioned documents. The tests used in the scientific examination of questioned documents are many and varied. One examination may concern a specimen of typewriting and the determination of the make and model and perhaps the year of manufacture of the typewriter. The tests used to establish this involve the precise measurement of the shape and size of the letters, and their comparison with known standards. The problem may involve deciding whether two samples of handwriting were made by the same person. One of the most important matters is that involving the establishment of the difference or identity of two or more samples of paper stock. Tests were performed with the Herzberg and the Lofton Merritt stains. Small samples were cut out for this experiment. This would not necessarily be required as the procedure can readily be modified to be used as a spot test on the original sheet. This technique proves to be quite valuable as a corroborating demonstration that specimens of paper from questioned documents are either similar or dissimilar.
