DICTIONARY OF ORGAN STOPS. 109
Another maxim here followed (Swell Mixture, a) is that the Quint is not
to be introduced in the upper portion of the compass unless used through-
out. The same applies to other odd-numbered partials of the 16 ft. tone.
Readers will notice that the Tierce and Flat Septime (q.v.) are incorpor-
ated in these schemes. Scheme No. 4 is planned on altogether different
lines. It represents the Mixture schemes used by Messrs. Norman &
Beard, the celebrated Norwich firm, at Westminster Roman Catholic
Cathedral, London (Temporary Sanctuary Organ).
(4) Great organ. CC to Ftf, 19 notes: 15, 19, 22. Fid. G to C,

The next scheme, No. 5, is that of the Great Organ Mixture at the
London Organ School, Princes Street, W. (Positive Organ Co.). It was
designed by Mr. Thomas Casson and his colleague Mr. Raeburn Andrew,
M.A. There is a separate Twelfth and Fifteenth, the soundboard is also
carried up for an extra octave to accommodate the octave coupler. The
—4 refers to a rank which actually runs a fourth below the unison. It is
a twelfth to the manual 32 ft. tone (Dolce, 32 ft.).
