Errors caused by failure to read ascale with the lrne of sight in the proper position are saidto be due to Parallax. The following method will avoidsuch errors: Take a piece of stiff paper about 1J X 4 inches, beingsure that the upper edge is clean and straight. Wrapitaround the cylinder, and allow a portion to project, asshown in Fig. 48.

In this position the sight is horizontal.If the upper edge of the paper is just on a line of thescale, this gives the reading; but if not, the fraction mustbe estimated by the eye and expressed as a decimal.
