The smaller species of lobster and other crustaceous animals 
may be preserved and transported without the removal of the 
fleshy matter. Great care, however, is necessary in packing 
all of them, to prevent the destruction of their claws and feelers. 
Smaller ones should be put up in cotton, wool, or other soft 
material. 
Asterias , or star-fish, are difficult to preserve; they must be 
immersed in fresh water several hours, and then extended on a 
plank and the rays pinned down until dry. The flesh should 
be removed from the larger species, and some preservative in¬ 
troduced. Great care is necessary in packing them. 
Echini and Spataugus , sea urchias and sea eggs. These 
are also difficult to preserve, in consequence of the spines, which 
are very difficult to retain in their natural positions. They are 
also very liable to fall off by their own weight whilst drying. 
The interior of the shell should be removed by enlarging the 
anal opening. It should then be immersed for fifteen or twenty 
minutes in fresh water, and on being taken out it should be 
filled with cotton, and the same material placed among the 
spines to support them, and then exposed to dry. The packing 
necessarily requires great care. 
Entozoa , or worms, are best preserved in spirits, as are also 
arachnides or spiders. The latter, however, particularly the 
larger ones, are liable to shrink up in the body, to prevent 
which a puncture should be made, the contents squeezed out, 
and the cavity filled with cotton. 
Insects .—The whole of the class, with a few exceptions, as 
butterflies, moths, and sphinges, had better be preserved in 
spirits. Butterflies, &c. should be preserved by having a pin 
run through the body and into a soft board; whilst the wings 
should be kept extended by strips of paper pinned across them. 
Notes should be taken of such as are useful in the arts or 
otherwise. 
The collector of insects should have constantly in his pocket 
a small vial, (2 ounce,) with a large mouth, and containing a 
small quantity of spirits, in which to secure and preserve such 
as he may occasionally catch. There is a long thin species of 
pin made especially for the purpose of securing those little
