The Technical College Set of Mathematical Instruments

    Abstract

    THERE is great diversity of opinion as to the most suitable case of drawing instruments for students, many colleges having their own particular cpecifications; but it would be difficult to find a more desirable set of instruments than this of Mr. Harling, on account both of the judgment displayed in the choice of the instruments and the design and workmanship exhibited. In the neat pocket case will be found a 4-inch bow compass, with pen and pencil fittings and lengthening bar; a 5-inch hair divided; three spring bows; two drawing pens; a pricker; keys, spare leads, and needles. The instruments are of the best English design and finish, with knee joints and nut and bolt needle points where necessary.
