diately ensuing, and fully to be compleat and ended, according to the Statute
in such case made and provided; in which said Letters Patent is contained
a proviso that if I, the said Daniel Bridges, should not particularly describe

same is to be performed, by an instrument in writing under my hand and
seal, and cause the same to be inrolled in His said Majesty's High Court of
Chancery within four calendar months next and immediately after the date

NOW KNOW YE, that I, the said Daniel Bridges, in compliance with
the said proviso, do hereby describe and ascertain the nature of my said
Invention, and declare that the same is to be performed in manner following
(that is to say):-
To Refine Sperma Ceti-After it is well pressed, and the oil taken from
it, boil it well with any sort of soapmakers' ley 'till it is perfectly white; when

page_text: this is done, boil the white sperma ceti with clean water for one hour or more,
adding a little common salt, or a vitriolick acid in the boiling.
For Making the Candles.-Wax must be added to every pound of sperma
ceti, in order to break the flake or grain of the sperma ceti, and render it
one uniform body, which was never done 'till my Invention thereof.
In witness whereof, I, the said Daniel Bridges, have hereunto set my
hand and seal, this Nineteenth day of October, in the year of our
Lord One thousand seven hundred and seventy, and in the tenth
year of the reign of our said Sovereign Lord George the Third, by the
grace of God of Great Britain, France, and Ireland King, Defender of
the Faith, and so forth.
