page_text: FIRST OPERATION.
First Take 16 ounces by weight of Norwegian Pitch, and heat it in a water
bath, by which heat the pitch is rendered fluid; it is then strained and afterwards
allowed to cool.
I
Second-Take 32 ounces of cane sugar, in powder, mix it with 46 ounces of
bicarbonate of soda in powder, and with the foregoing. ingredients mix the mass of
pitch, and triturate the whole in a mortar for three hours.
Third After said trituration is complete take 10 fluid pounds of distilled water,
and add it in portions to the above triturated mixture which is in the mortar, and
continue the operation of trituration with the water until the whole has been
mixed with the water, keeping up the operation of mixing and trituration for four
hours.
Fourth At the end of this time the mixture which is in the mortar, of water,
pitch, sugar, and bicarbonate of soda, is to be placed in a suitable vessel and
heated to the temperature yielded by a water-bath, and stirred with a glass rod for
a period of five hours, after which the mixture is removed and allowed to stand
for three days; it is then to be filtered. The mixture is now ready to be dialysed.
The object of mixing the water, sugar, and bi-carbonate of soda, with the pitch is
to facilitate the separation from the pitch; by dialysis, of the poisonous and
injurious principles, or substances, while the useful principles, or, substances are
retained.

of the bad or poisonous principles which become volatilized by the heat.
Vegetable pitch may be said to be composed of two parts; one portion consisting
of combined dense empyreumatic resinous matters of dark color, and the other
portion of liquid nature which holds in solution the first part. The acrid and
nauseous odour of the raw pitch is due to the poisonous or hurtful substance in
what is mentioned as the second portion of the pitch. Some of these poisonous or
hurtful substances of the pitch are pyroligneous acid, formic wood spirit or
methylic alcohol, aldehyde acetones, methylic acetates, creosote, cyanides of
ammonia, benzines; and these substances by means of the bicarbonate of soda
become capable of being removed by the operation of dialysis, as before described.
The useful or medicinal substances which remain in the pitch after the dialysation
are chiefly the resinous bodies. The operation of lixiviation makes a complete
extract of the pitch which is imprisoned in the sand. Every portion of the liquid
vehicle when it comes in contact with the sand containing the pitch becomes
charged with a proportional quantity thereof and each portion of the liquid'
vehicle takes up a portion of pitch until the whole has been completely dissolved,
and all the pitch contained in the sand joined to the water, alcohol and glycerine
these three bodies being powerful and inoffensive solvents, and being the vehicle of
which most fluid extracts are made.
This compound or fluid extract of dialysed pitch thus prepared is of great
medicinal value, as the hurtful substances have been removed; it is used for
various medical purposes, such as treatment of bronchitis, of throat diseases, of
ulcers of all kinds, genital diseases, syphilis, herpes, chronic rheumatism, scrofula,
and sores of every nature. The ordinary dose is one table spoonful of the compound
in a cupful of sweetened water, administered internally once in two to four hours,
according to the nature of the disease. The compound may also be applied
externally for the cure of all kinds of sores, and diseases of the skin.

SECOND OPERATION.
Dialysis of the Mixture.-Take the solution of pitch and place it in an ordinary
dialysing apparatus which it is unnecessary to fully describe it being made with
vegetable parchment in the usual manner. The dialyser is placed within a suitable
vessel containing distilled water, upon a level table, care being taken that the level
of the exterior liquid is the same as the level of the liquid contained within the
parchment or dialyser. The whole is allowed to stand three days, at the end of
which time the exterior water is removed, and a new quantity substituted. The
first water is then tested with sulphuric acid, and note is taken whether there is
any effervescence, or discharge of carbonic acid. If there is the dialysation is
continued for three days more, when the exterior liquid is again tested in the same

Having now particularly described and ascertained the nature of the said
Invention and in what manner the same is to be performed I declare that what
I claim is;
1. The combination with colloid vegetable pitch of glycerine and alcohol, sub-
stantially as herein set forth.
2. The herein described composition, which consists of colloid pitch or pitch
deprived of the lighter distillates such as wood spirit, the acetones, aldehydes,
creosote etc; combined with glycerine and alcohol in substantially the proportions
herein stated.
