For instance

« A Water-Museum », St Nicholas: an illustrated magazine for Young folks, vol. 12, partie 2, Londres, 1885, p.785.

The intelligent museum-keeper will carefully study the habits of his specimens and adapt his means to their needs and peculiarities. For instance, the caddis-worms need a supply of small sticks and grasses to keep their houses in repair, and the water-scorpion dreads the sunlight… The caddis-worms in their odd little houses of sticks, stones, and shells were always up to mischief; sometimes one would catch hold of a patient snail and try to glue it to his house, and after a struggle, in which the strong snail would manage to get away. Mr Caddis would hide his head in the grass and keep still as if felt very foolish and ashamed. At other times they would have a wrestling match, and we would heartly laugh to see them push and tug one another about.
