The above ingredients are those of the shops, and as denominated and generally
sold therein; the caoutchouc solution is made by thoroughly dissolving 1 part
caoutchouc in about 9 parts of benzoline spirit.
The above ingredients are incorporated together as follows :—
First add No. 3 and No. 4 to No. 1, then thoroughly amalgamate, keeping the air
from the place of mixing as far as possible. To this mixture add No. 5, which

thoroughly mixed or blended together; then thoroughly mix all of these ingredients
and add Nos. 6, 7, 8, 9, either separately or previously mixed together; then add
No. 11; now mix thoroughly for some two or three hours according to the quantity
and until all the ingredients are thoroughly amalgamated or blended together. The
resultant mixture must then be allowed to stand in the mixer, and the latter kept
air tight for some six hours, when it will be ready for use, and may be applied in
one or more coats as desired. I am aware of the Letters Patent for "Improvements
in Compositions for Protecting or Preserving Ships' Bottoms and other Submerged
Surfaces, also Applicable to Stone and other Building Material," bearing date
September 15th, 1879, No. 3690, and I disclaim any part of the Invention covered
by the said Letters Patent.
