DIRECTION! FOR FRRDBBVATIW OF FISH 
when collecting in the field, I always take a two-gallon collecting 
bucket end sufficient formalin to fill it when mixed with water two-third 
full. This formalin, should be nixed in the proportion of one part 
commercial formadehyde with nine parts water? sea water preferable when 
available. Into this bucket I place the fish as caught, trying not to 
leave than to die in the seine, -.hen they die in the formal in they make 
much better specimens , and aro better preserved than those that die 
before being placed in the formalin. This bucket can be filled completely 
full of fish but they should not be packed in it like sardines in a can. 
At the end of the clay of collecting, these fish should be transferred 
i -mediately from the collecting bucket to jars for storage fox' ton days 
with formalin mixed as indicated above, hach jar should have placed In 
it a numbered tin tagoor a label with all essential data in regard to 
locality, data, collector, etc. This paper should be written on with lead 
pencil • Ordinary paper will go to pieces in formalin so only linen paper 
should be used for fo.sr.mlin or alcoholic preservation. 
After the fish have been in the jars for a week or ten days, they 
should then be wrapped in cheesecloth packages along with tin tag or 
labels and tied firmly, but not so firm that the strings will cut into 
the fish* These cheesecloth packages of fish should be placed in tank 
about two-thirds full of seventy-five per cent alcohol. 
Any fish too large to bo pie cod into the lass jar should be tin 
tag -ed and all tag numbers should be recorded in a record book along 
with essential data. Tin tags may be tied on the fish with linen 
thread through the lower, jaw. Any fish over three inches in length 
sho ild have its abdomen out so that the formalin can enter, hay fish 
too large to go into a two-quart jar should be injected with a sol tion 
of formalin mixed with equal parts of formaldehyde and equal parts of 
water. Injection of the mussels should occur every two or three inches 
and when these large tin tagged fishes are completely injected, including 
the abdominal cavity, they then can be dropped into a tank of formalde- 
hyde mixed up on© part of formalin and nine parts of water. 
After these tin tagged fish have been placed in the formaldehyde for 
a week or fen days, they say be removed and placed in the alcohol tank 
along with those wrapped up in cheesecloth packages • When a sufficient 
quantity of tin tagged fish and wrapped specimens have accumulated they 
can be packed in the alcoholic tank for shipment. These should be 
packed snugly so that they cannot shake around. All tin tagged fish 
should be wrapped in. cheesecloth.
