670 PROCEEDINGS OF THE INSTITUTION. APPENDIX. METHOD FOR DETERMINING THE DIRECTION OF "LENGTH" AND "WIDTH" OF PAPER, FOR USE IN CARRYING OUT THE TESTS SPECIFIED IN CLAUSES 4, 5, 6 AND 7. (See Fig. 6.) The direction of the "length" and "width" of the paper may be ascertained by the "Direction Test" as follows:— Let a strip about ½ in. width and 5 in. length be cut from one edge of the sheet under test and a similar strip cut from the adjacent edge at right angles to the first strip. On attempting to hold these strips vertically in the air between the finger and thumb they will fall over as shown in Fig. 6. The upper strip "A" has its fibres parallel to the length of the strip and serves to indicate the edge from which it was cut as the "length" of the paper. The other strip "B" indicates the "width" of the paper. Should the "length" strip, by chance, be the undermost one when held between the fingers, the strips will be touching each other. If the strips be waved over in the opposite direction to right or left, this will separate the strips and bring the "length" one uppermost. FIG. 6.—Test for "length" and "width."
