The invention relates to parallel rulers, and consists in making a slot longitudinally in the wood, metal, gu'tta-percha, or other material of which it may be formed, in order to enable one using it to see, without stooning, rising,
or changing his position (at a table or desk) the figures under which a balancing-lineis to be drawn, the same being thus readily done without danger of blotting. I

The operation is as follows: The ruler is placed on a ledger and moved up'and down,
