PROVEMENTS IN THE MANUFACTURE OF BISCUITS."
"IM-
This Invention, which relates to the production or manufacture of a highly
nutritious biscuit, consists essentially in the employment of lentils as the basis of
the manufacture.
For the purpose of this Invention the lentils are ground to a fine flour, which
may be used alone as the basis or staple of the manufacture.
In manufacturing biscuits according to this Invention the lentil flour is used
with the other biscuit making materials, such as sugar, butter, tartaric acid, soda,
milk, or water, in the usual or other desired proportions, and there may be added
thereto a flavouring substance, such as ginger, lemon, or other such like substances.
The biscuits manufactured as herein-before described have not the highest
nutriment by virture of the fact that the lentil is deficient in phosphorus. When it
is desired to produce a biscuit of the maximum nutritious quality in respect of
phosphorus, a substance containing phosphorus is added to the lentil flour. Oatmeal
is used for this purpose, or any equivalent phosphorus yielding substance may be
substituted.

the said 'Robert Hamilton in the Great Seal Patent Office on the 23rd
December 1879.
ROBERT HAMILTON, of the Town and County of Dumfries, North Britain. "IM-
PROVEMENTS IN THE Manufacture of BISCUITS."
My Invention relates to the production or manufacture of a highly nutritious
biscuit, and consists essentially in the employment of lentils as the basis of the
manufacture.
For the purpose of my said Invention the lentils are ground to a fine flour, which
may be used alone as the basis or staple of the manufacture.
In manufacturing biscuits according to this Invention the lentil flour is used with
the other biscuit making materials, such as sugar, butter, tartaric acid, soda, and
milk or water, in the usual or other desired proportions, and there may be added
thereto a flavouring substance, such as ginger, lemon, or other such like substance.
The biscuits manufactured as hereinbefore described have not the highest
nutriment by reason of the lentil being deficient in phosphorus. When it is desired
to produce a biscuit of the maximum nutritious quality in respect of phosphorus a
substance containing phosphorus is added to the lentil flour. Oatmeal may be
used for this purpose, or any equivalent phosphorus yielding substance may be
substituted.
The materials are or may be incorporated and baked in manner which is practised
in manufacturing ordinary biscuits.
Having now described and particularly ascertained the nature of my said Inven-
tion, and the system, mode, or manner in or under which the same is or may be
used or practically carried into effect, I would observe in conclusion that what I
consider to be novel and original, and therefore claim as the Invention secured to
me by the herein before in part recited Letters Patent is,—
The hereinbefore described improvements in the manufacture of biscuits, con-
sisting in the employment of lentils as the basis of the manufacture.
In witness whereof, I, the said Robert Hamilton, have hereunto set my hand
and seal, this Ninth day of December, in the year of our Lord One thousand
eight hundred and seventy nine.
