Mth nets having closed ends, or which are tied shut and used 
without the glass tube, the material collected in the end of the townet can, 
inverting the net, be washed into a wide— mouthed bottle or tumbler or tin 
fruit can, and tnen be transferred to the homeopathic vials or bottles in 
whicn it will be stored* An easy way to Make this transfer is to pour the 
concent ated material on little squares or circles of fine bolting silk or, 
if this is not available, very fine muslin or cheesecloth two or three inches 
in diameter; then place cloth and all in the preserving fluid, which is 75% 
or, if added to vial containing some water together with animals, 9556 may 
be used on them direct# 
CRUSTACEA # 
These are best preserved in 70% to 75% alcohol, but it is well to 
kill larger forms in about 40m or 50$, or, better, let them die in fresh 
water* In the case of crabs, these need to be individually killed* A row 
of tin cans obtained from the cook will serve the purpose. If several crabs 
go through their death throes in one container they often tear one another 
to pieces or else become so dismembered that they lose value as specimens* 
Shrimps are desirable specimens. If you save any from the stomach 
contents of marine mammals or fish, pick out specimens in reasonably good 
condition. Whale and fish parasites of all kinds are much desired* 
COEIEMERATES * other than jelly f i sh* 
These include the alcyonarians or soft or fleshy corals, whip 
corals, sea pens, and sea anemones • They are preferably preserved in alco- 
hol* However, formalin will do temporarily for all of them* With respect 
to the sea anemones, it is perhaps as good as alcohol* 
Always preserve in formalin, 5%. That is the strength we always 
use, roughly one part of the commercial article in twenty parts of water. 
STARFISH AUD BRITTLE STARS # 
If convenient, it is considered best to allow true starfish to 
reach a normal state of expansion in a pan of fresh sea water. From this 
tney should be transferred to fresh water, both to kill them and to plump 
th era up, which happens as a result of osmotic action. Brittle stars do 
well if placed in pan of alcohol well separated, when they will die flat. 
If you wish to preserve your specimens dry, or have sane that are too 
large to place in available containers, they should be soaked several days 
in 5% formalin and then dried as raoidly as possible (but not baked or 
boiled). If you can bottle your specimens, it is best that they go into 
alcohol after the plumping process, but here you have to be careful to 
watch the strength of your alcohol, because echinoderms , with a water vas- 
cular system, carry over a tremendous lot of water into the preserving solu- 
tion. If pressed for time, place all specimens of echinoderms in 70 % 
alcohol and bring it up to strength again after a day or two, and two days 
later once more.
