The two alphabets proposed by blind individuals (Alexander Hay, and Robert Milne) are among the more abstract. Milne’s in particular is minimalist, with letters A-P oriented around a horizontal bar, and Q-Z around a vertical bar. These and a few others (Richardson, Ponton) show some similarity to optical telegraph systems (e.g., Chappe); others are reminiscent of stenographic systems. Some (McPherson, Lothian) appear to combine telegraphic and stenographic symbols.

Milne is unlike Braille, yet shares its minimal form, and complete departure from Roman or even stenographic alphabet. Robert Milne had with David Macbeath developed a string alphabet for the use of the blind (Macbeath and Milne, 1822).

Fry’s (1833) is a sans serif font. (Wm Caslon’s foundry had issued a sans serif in 1816.) The idea may have been that serifs bore no information — for tactile readers — and so could be dispensed.

Milne’s alphabet follows another logic: retain a spine, from which serif-like appendages bear the clues for differentiating one symbol from another. The permutations unwind along the horizontal bar until, exhausted, they pick up on a vertical — so much for the efficiency of a monospaced letter, such as Braille offers. The logic also takes no account of letter-frequency in English. The Hay (blind) and Walker alphabets are close to monospaced. Hay uses a variety of differentiating elements that are more heterogenous than is absolutely necessary. Walker employs a common cryptographic device called a pig pen cipher, and exhausting his vertical and horizontal variations A-R, turns to diagonal spines for S-Z.

Craig’s alphabet (fourth from bottom) is interesting not so much for its centerline, than its minimal components : will count when leisure allows, but there may even be opportunities for further compression, e.g., the bowls for letters K-N might be assembled from the components for J, which themselves suggest possibilities for letters D and G.

Pamela Lorimer writes: “Some of the authors of arbitrary codes for the competition... seemed carried away by the enjoyment of making a series of patterns with little idea of the perceptual and cognitive problems involved. The arbiter was the Reverend William Taylor of the York School, who being sighted, it is not surprising that he chose the entry of Dr Fry of Bristol, who had used the simplest form possible of capital letters using no serifs. A reader with sight always finds it difficult to assess the qualities of a code intended to be read by touch, and even a blind person needs practice before an unbiassed opinion should be given. Comments on all codes therefore need to be made with caution. The organisers of the competition had hoped that one best type would result from their project. In fact, it had the opposite effect for the number of codes multiplied. They little realised that unity within Britain would not be achieved until nearly 40 years later.”
