PROVISIONAL SPECIFICATION left by the said William Britton
Stephens at the Office of the Commissioners of Patents, with his
Petition, on the 3rd January 1873.
I, WILLIAM BRITTON STEPHENS, of 67, Strand, in the City of West-
minster, Gentleman, do hereby declare the nature of the said Invention
for "IMPROVEMENTS IN THE MANUFACTURE OF PAINTS," to be as follows:-
The improvements consist in the application and use of slacked lime
or plaster of Paris, one or the other or both, instead of or in combination
with the usual bases employed in the manufacture of paint.
The improvements may be performed by taking freshly burnt lime or
plaster of Paris, slacking in the ordinary way, grinding or pulverizing,
then mix and use as a vehicle or bases for paint, or combine with the
basis in general use.

page_text: I find that the following proportions give fair results, but I do not
bind myself to them, as they may be varied to almost any extent :-Take
20 cwt. of plaster of Paris or 20 cwt. of freshly burnt lime, add 16 cwt.
of water, and slake; when slaked grind with 3 cwt. of white lead.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said William Britton Stephens in the Great Seal
Patent Office on the 3rd July 1873.
