sters and Crabs by breaking the smallest possibie piece from 
their points and introducing a small crooked wire; in the 
smaller claws the flesh must be allowed to dry, and to fa- 
cilitate this, extremely small perforations should be made in 
opposite sides of the shell by means ef a sharp triangular awl, 
so as to allow the air to pass through it. 
In Lobsters the branchize and all the intestines must be 
cut away, the latter is effected by separating the body from 
the lower paris, and then extracting the internal parts with 
any sharp instrument; it should then be dried and cemented 
together, after being well anointed with the preservative. In| 
Crabs, the body, with all the limbs attached, is pulled sepa- 
rate from the back shell, and the whole fleshy matter carefully 
picked out, and preserving powder and the solution of corro- 
sive sublimate applied to the different internal parts. In dry- 
ing Lobsters, Crabs, &c., they should be exposed to a free 
| current of air, but not to the sun’s rays, as it reddens the 
shells of crustaceous animals. 
It need hardly be mentioned, that before applying the pre- 
servatives, the shells should be well washed with cold water. 
The Hermit-Crab (Pagurus Bernhardus), always takes pos- 
session of the shell of some turbinated Univalve as its domicile. 
These are easily preserved by pulling out the animal after it is 
dead. An incision is made in the soft tail of the animal, and 
the contents allowed to run off; it is then filled with cotton 
and imbued with the preservative, some cement is then put on 
the tail, and the animal returned to its shell ; which completes 
the operation of preserving. 
In sending home crustaceous animals, the larger specie-~ 
| should be emptied of their fleshy matter, which, however, is 
not necessary with the smaller species ; they should be packed 
in middling sized cases, and each wrapped in separate papers, 
with a thick bed of cotton or flax between each. In Lob- 
sters, and the species which are allied to them, great care 
must be exercised in preserving the tentacula or feelers which 
emanate from their heads, as these become very brittle after 
they are dried, In proceeding to set up specimens which have 
been sent home, they should be immersed in cold water for | 
sume time to give pliability to the tentacula and other parts,
