At the ends, and in themiddle, of the longer rulers, as also at the endsof the shorter, are holes, upon the exact fixing ofwhich the perfection of the instrument chieflydepends.

The instrument is fitted toge-ther for use by several little pieces, particularly alittle pillar, No. 1, having at one end a screw andnut, whereby the two long rulers are joined; andat the other a little knot for the instrument toslide on.
