Gartside, Mary: An Essay on Light and Shade, on Colours, and on Composition in General (London, 1805)

TO THE RIGHT HONOURABLE

LADY SOPHIA GREY.

X H E permission to address this little work to
Your Ladyship, is not the least of the many favours you have
conferred upon me.

Duty to my Pupils, and some hope that it may be of
use to accelerate their progress in an Art you encourage, induced me
to undertake it; and it is both my pleasure and my pride to have
this public opportunity of assuring Your Ladyship that I am, with
the greatest gratitude and respect,

Your most obliged

and most devoted Servant,

M. GARTSIDE.
