  1. For instance, some neatly picked fillets of anchovies, wiped free from oil, and the skin and bones removed, can be laid on the green butter; over them a slight sprinkling of sliced olives, then the lettuce leaf, &c., as previously described.

Original Text
Fish may also be used in this fashion:—caviare, smoked salmon, cod's roe, lobster, herring à la sardine, sardines, lax, preserved tunny, and anchovies. For instance, some neatly picked fillets of the last-named fish, wiped free from oil, and the skin and bones removed, can be laid on the green butter; over them a slight sprinkling of sliced olives, then the lettuce leaf, &c., as previously described. Caviare should be plainly spread on the butter, with a few drops of lemon juice and a dust of Nepaul pepper.
