This historic book may have numerous typos and missing text. Purchasers can download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1895 Excerpt: ...of the index above the next lower line (4.16) of the rod. We shall now determine this distance. Observe which line of the vernier is exactly opposite a line of the rod. In this case, the line of the vernier numbered 7 is opposite a line of the rod. Then, since each division of the vernier exceeds each division of the rod by IU,0?5 of a foot, 0 of the vernier is lt'at of a foot above the next lower line of the ml. 6 of the vernier is,00 of a foot above the next lower line of the rod. 4 of the vernier is j 03 0 of a foot above the next lower line of the rod. 3 of the vernier is yj of a foot above the next lower line of the rod. 2 of the vernier is 105'jj of a foot above the next lower line of the rod. 1 of the vernier is T0oS of a foot above the next lower line of the rod. 0 of the vernier is T5705 of a foot above the next lower line of the rod. Hence, the required reading is 4.16 + 0.007 = 4.167 feet. In general, the following rule is evident: More the vernier until its zero line is at the required height; read the height to the nearest hundredth below the index, and write in the thousandths' place the number of the division line of the vernier which stands opposite any line of the rod. Second form. In this form (Fig. 10) the graduated part of the vernier is r$v of a foot in length, and is divided into ten equal parts. Hence, one division of the vernier = of Tg5 =Tj05 of a foot; and one division of the vernier is less than one division of the rod by i U--TtfW = Tai of a foot. The height of the index of the vernier in Fig. 10 is 4.16 feet, increased by the distance of the index from the next lower line (4.16) of the rod. We shall now determine this distance. We observe that the line of the vernier, numbered 7 stands exactly opposite the line Fig. Io. o...
