PROVISIONAL SPECIFICATION left by the said John Barrow at the
Office of the Commissioners of Patents, with his Petition, on the
9th December 1858.
I, JOHN BARROW, jun., of the City of Manchester, in the County of
Lancaster, Manufacturing Chemist, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN THE TREATMENT OF COAL GAS TAR, AND OF THE
OILS OBTAINED BY THE. DISTILLATION OF THE SAME, AND FOR THE APPLICATION OF
BSTANCES OBTAINED THEREBY," to be as follows:-

page_text: bodies known as the oxide of amyl, the hydrated oxide of amyl, the chloride
of amyl, the acetate of amyl, or the carbonate of amyl, with or without the
addition of the hydrated oxide of ethyl or methyl, or of bodies derived there-
from. Or, I distill coal tar alone, and after separating the naptha which
distills over for rectification, in the usual way, I collect the succeeding oils,
which I submit to any of the well-known means of purification, and I mix
the purified or partly purified oils with suitable proportions of oxide of amyl,
hydrated oxide of amyl, or the chloride, acetate, or carbonate of amyl, and
distill the mixture in any suitable apparatus. Or, I mix together in any suit-
able proportions purified coal tar oil and the oxide, hydrated oxide, chloride,
acetate, or carbonate of amyl, with or without the addition of hydrated oxides
of ethyl or methyl, or of bodies derived therefrom, and with or without the
process of distillation; and the oils obtained by any of these processes I apply
to the purposes of illumination, lubrication, or other purposes for which they
may be found applicable. The lighter and more volatile oils I apply to
illumination, and the heavier and less volatile to lubrication, either alone or
mixed with other bodies, such as animal and vegetable fats and oils, tallows,
lard, lard oil, neatsfoot oil, cod or whale oil, palm oil, rape, olive, Gallipoli, and
linseed oils, or the fats obtained by the rendering of animal matters or
substances.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said John Barrow, junior, in the Great Seal Patent Office on
the 8th June 1859.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, Jonn
BARROW, junior, of the City of Manchester, in the County of Lancaster,
Manufacturing Chemist, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Ninth day of December, in the year of our Lord One
thousand eight hundred and fifty-eight, in the twenty-second year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
John Barrow, junior, Her special licence that I, the said John Barrow, junior,
my executors, administrators, and assigns, or such others as I, the said
John Barrow, junior, my executors, administrators, and assigns, should at any
time agree with, and no others, from time to time and at all times thereafter
during the term therein expressed, should and lawfully might make, use,

page_text: exercise, and vend, within the United Kingdom of Great Britain and Ireland,
the Channel Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN
THE TREATMENT OF COAL GAS TAR, AND OF THE OILS OBTAINED BY THE DISTILLATION
OF THE SAME, AND FOR THE APPLICATION OF SUBSTANCES OBTAINED THEREBY," upon
the condition (amongst others), that I, the said John Barrow, junior, by an
instrument in writing under my hand and seal, should particularly describe
and ascertain the nature of the said Invention, and in what manner the
same was to be performed, and cause the same to be filed in the Great
Seal Patent Office within six calendar months next and immediately after
the date of the said Letters Patent.
NOW KNOW YE, that I, the said John Barrow, junior, do hereby declare
the nature of my said Invention, and the manner in which the same is to be
performed, to be particularly described and ascertained in and by the following
statement (that is to say):-
I submit to the process of distillation, in any convenient apparatus, a
mixture in suitable proportions of coal gas tar and any one or more of the
bodies known as the oxide of amyl, the hydrated oxide of amyl, the chloride
of amyl, the acetate of amyl, or the carbonate of amyl, with or without the
addition of the hydrated oxides of ethyl or methyl, or of bodies derived there-
from. Or, I distill coal tar alone, and after separating the naptha which first
distills over for rectification in the usual way, I collect the succeeding oils,
which I submit to any of the well-known means of purification, and I mix
the purified or partly purified oils with suitable proportions of oxide of amyl,
hydrated oxide of amyl, or the chloride, acetate, or carbonate of amyl, and
distill the mixture in any suitable apparatus. Or, I mix together in any
suitable proportions, purified coal tar oil and the oxide, chloride, acetate or
carbonate of amyl, with or without the addition of hydrated oxides of ethyl
or methyl,or of bodies derived therefrom, and with or without the process of
distillation; and the oils obtained by any of these processes I apply to the
purposes of illumination,lubrication, or other purposes for which they may be
found applicable. The lighter and more volatile oils I apply to illumination,
and the heavier and less volatile to lubrication, either aloue or mixed with
other bodies, such as animal and vegetable fats and oils, tallow, lard oil,
neatsfoot oil, cod or whale oil, palm oil, rape, olive, Gallipoli, and linseed oils,
or the fats obtained by the rendering of animal matters or substances.
Having thus fully described the nature of my said Invention and the
manner in which the same is to be performed, I desire it to be distinctly
understood that I claim, the use and application of the oils obtained by any

page_text: or all of the processes herein described, for the purposes of illumination or
lubrication.
In witness whereof, I, the said John Barrow, junior, have hereunto set
my hand and seal, this Seventh day of June, in the year of our Lord
One thousand eight hundred and fifty-nine.
