In doing this delicate operation, take munch care not to 
pierce the shell or break the mouth. 
When the animals are out, wash the shells and shake out 
the water and the interior dirt and place them on paper to 
dry ; but not to the sun. 
When dry, put some cotton in the mouth and paste the 
operculum on it. 
Small species will be packed in glass tubes or small boxes 
with cotton. 
Should they be large, wrap each one separately in a paper 
and pack them in a box with soft substance. 
It is useless to clean the very small species. 
» 
Others, for their particular forms cannot be cleaned, kill 
them and put them near ant's nest ; if the ant's come to them 
they will eat entirely the animals, and the work wrill be 
done. 
If not, let them dry and pack them with care as the 
Send a few specimens of each species in bottle with spirit 
to study the animals.
