Bernard’s essays in The London Mercury, see here, are fascinating, and will feature more in this blog I reckon over coming days and weeks.
As a starter take this illustration from his essay titled About Type-Design, itself reproduced from Frederic Goudy‘s The Alphabet. A key to the figures: 1 – Trajan; 2 – pen form; 3 & 4 – Gothic and Lombardic; 8 – Jenson; 9 & 12 – Kennerley (Goudy); 10 & 13 – Caslon; 11 & 14 – Bodoni.
