_Sun-Dial Motto_ (Vol. v., p. 499.).--Y. is informed that Hazlitt, in his
_Sketches and Essays_, has an essay on a sun-dial, beginning with these
words:
"_Horas non numero nisi serenas_, is the motto of a sun-dial near
Venice."
In _La Gnomonique Pratique_ of François de Celles, 8vo., there is pretty
long list of Latin mottos for sun-dials, but I do not find the above
amongst them. It scarcely reads like a classical quotation.
