From TIMOTHY TREFFRY
The question of sunrise and sunset times and their relationship to the
solstices (Letters, 5 February and 5 March) has been very nicely explained
by Sheffield astronomer David Hughes in an article in the December issue
of the Horological Journal. A free copy of the December issue is available
on request from the British Horological Institute, Upton Hall, Upton NG23
5TN. Please send an address label and a 43p stamp.
