PROVISIONAL SPECIFICATION.
Improvements in and relating to the Treating and Preserving of
Fish.
I, WILLIAM GIBSON PURSELL, of Rhynd Lodge, Leith, in the County of Mid-
lothian, Merchant, do hereby declare the nature of my said invention to be aš
follows:-
This Invention has reference to and comprises a new or improved process, or
inode and means, of treating and preserving haddocks and other fish, and consists in
first sinoking them after they are split and the internal parts removed, and before
treating them with the preserving mixture. The smoked fish are then packed in
barrels or boxes, each layer being sprinkled with Boracic acid, or with a mixture of
Boracic acid and salt, or with a composition containing either Boracic acid or Borax.
The Boracic acid or Borax mixture or composition, may if found more suitable be
dissolved and poured or spread over the fish, either after they are put in the barrels,
or boxes, or before they are packed. In the processes heretofore in use for treating
fresh fish before being smoked, the bad effect was produced of destroying the delicate
gloss which characterises a fresh fish when smoked, and also a streak of blood was
very apparently seen, which is another characteristic sign of an old fish. While by
my new process of first smoking Findon or Eyemouth Haddocks or other fish before
treating them with the preservative mixture, both of the above evils are avoided, and
the fish will be always ready for market in a perfect condition.
COMPLETE SPECIFICATION.
Improvements in and relating to the Treating and Preserving of
Fish.
I, WILLIAM GIBSON PURSELL, of Rhynd Lodge, Leith, in the County of Mid-
lothian, Merchant, do hereby declare the nature of my invention, and in what
manner the same is to be performed, to be particularly described and ascertained
in, and by the following statement in writing, that is to say :—
This Invention has reference to and comprises a new or improved process, or mode
and means, of treating and preserving haddocks, herrings, and other fish, and
consists in first smoking them after they are split or opened up and the internal
parts removed, and before treating them with the preserving mixture. The smoked
haddocks, herrings, or other smoked fish are then packed in barrels or boxes, each
layer being sprinkled with Boracic acid, or with a mixture of Boracic acid and salt,
or with a composition containing either Boracic acid or Borax, or they may be so
spread over or sprinkled with the material before being packed in the barrels. I have
found the preserving mixture to be improved by adding about one pound of tannin
to each hundred pounds weight of the mixture, and in some cases this may be used.
The Boracic acid or Borax mixture or composition, may if found more suitable be
dissolved and poured or spread over the fish, either after they are put in the barrels,
or boxes, or before they are packed. In the processes heretofore in use for treating
fresh fish before being smoked, the bad effect was produced of destroying the delicate
gloss which characterises a fresh fish when smoked, and also a streak of blood was
very apparently seen, which is another characteristic sign of an old fish. While by
my new process of first opening up and smoking Findon or Eyemouth Haddocks,
herrings, or other fish before treating them with the preservative mixture, both of
the above evils are avoided, and the fish will be always ready for market in a perfect
condition.

page_text: Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed I declare that what 1
claim is.
First. The herein described process or mode and means of treating and preserving
haddocks, herrings, or other fish, consisting in first smoking them, after they are split
and the internal parts removed, and then treating them with Boracic acid, or borax,
or with a mixture or composition containing either of these, substantially as and in
the manner set forth.
Second. Haddocks, herrings and other fish treated and preserved substantially as
and in the manner herein set forth.
