HENRY ALFRED CHARLES SAUNDERS and ANDREW JAMIESON, both of 66, Old
Broad Street, in the City of London. "IMPROVEMENTS IN PROTECTING SUBMARINE
AND SUBTERRANEAN TELEGRAPH CABLES AND WIRES FROM THE DESTRUCTIVE
EFFECT OF TOREDO AND OTHER MARINE AND TERRESTRIAL ANIMALCULA AND
INSECTS."
The object of this Invention is to prevent the destructive effects of toredo and
other marine and terrestrial animalcula and insects upon the cores of submarine
and subterrancan cables and wires by the application of Andisoba oil to the serving
of the cores; and also to protect the hemp or other serving of the outer wires of
submarine cables from the same effects by the same means.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said Henry Alfred Charles Saunders and Andrew Jamieson in the Great
Seal Patent Office on the 11th October 1877.

EFFECT OF TOREDO AND OTHER MARINE AND TERRESTRIAL ANIMALCULA AND
INSECTS."
In order to preserve the cores and outer coverings of submarine cables or under-
ground systems of telegraph communication from the attacks of the toredo or
Price 11

page_text: terrestrial animalcula, the serving which immediately covers the core of the said
cable or telegraph system is, according to our Invention, saturated with Andiroba
oil either before or after the serving has been applied. This Andiroba oil is obtainable
from the Amazons, as well as British Guiana, and is simply an extract from the
palm which bears the same name (carpa guianensis), and has been found extremely
useful in preventing the ravages of white ants and other such destructive creatures,
and has been proved to have no detrimental effect upon the insulation properties of
gutta percha.
The strengthening iron, steel, or other wires or outer coverings should also be
served with serving saturated with this Andiroba oil, not only to prevent the
ravages of the toredo and animalcula, but also to preserve the same from corrosion.
This last property (vizt., of preventing rusting) has been proved to exist in a
remarkable degree, and consequently this treatment will preserve, maintain, and
prolong the life of a cable or underground wire far beyond that which it would
naturally have.
What we claim is, protecting submarine and subterranean telegraph cables and
wires by means of Andiroba oil, applied substantially as described.
In witness whereof, we, the said Henry Alfred Charles Saunders and Andrew
Jamieson, have hereunto set our hands and seals, this Eighth day of
October, in the year of our Lord One thousand eight hundred and seventy-
seven.
