Crabs, Lobsters, &c may be suffocated in spirits of wine or
turpentine, and then dried in an oven.
Sea Stars, after washing in fresh water, may be extended
on boards by means of pins, and when dry, laid between folds
of paper, packed in a box with a little camphor. In Echini or
Sea Eggs, the soft internal parts are to be extracted by the
anus: they are then to be stuffed with cotton, and carefully
packed with tow or cotton. Particular attention should be paid
to the preserving of the spines.
