No. 4 Small Yellow Shell
This is done in the same manner as No. 2 as regards the mixing and working, the only difference being in the body-colour.
No. 5 Brown and Purple Shell
This pattern has three veins and two French colours, or colours that have been mixed as French,—that is, with oil in them,—the last of which, in this instance, is the purple. Being mixed with a little more both of the gall and oil than the other, in order to make it flow out, over, and drive up the other colours, a marbler will be able, if he follows these instructions, to imitate any French pattern, whether there be more or less colours in them.
