The Johnson Standard.

For the bodies of our foundry (Mr MacKellar writes, in the Typographic Advertiser), we use as a standard a steel rod 35 centimeters long, which is divided into 83 parts, each part being equal to a pica body, and the twelfth part of pica (called a point) is the unit by which we measure our type. This steel rod serves also as a standard for the height to paper, which, being 2⅓ centimeters, make 15 type-heights equal to 35 centimeters. Gauged by our standard, the six principal bodies of the American foundries, from which the other bodies are supposed to be derived, show the following dimensions: Minion varies from 6¾ to 7¼ and brevier from 7⅝ to 8⅛ points. Bourgeois, while it is made as large as 9 points, differs generally but little from 8½ points. Long primer measures mostly from 9⅝ to 9¾, and in some foundries 10 points. Small pica varies from 10¼ to 11, and pica from 12 to 12 ⅙ points.
