In these two stages the young barnacle drifts about in 

 the sea. After passing through stage 2 they fix them- 

 selves — the common barnacle to stones, piles, the bottoms 

 of boats, &c. ; the ship barnacle to the bottoms of 

 ships, &c. ; and the crab barnacle to various kinds of 

 crabs. 



1 — Barnacle just hatched. 2 — Later stage of the same. 

 Magnified about 60 dia. 



These young barnacles are always found in the tow- 

 nettings during the early spring, and will be studied. 



Development of the Flounder . — The 

 egg of the flounder just before hatching. The newly- 

 hatched fish. When it issues from the egg, the little 

 flounder is a round fish, like the newly-hatched cod or 

 haddock. When it is about six weeks old the body 

 flattens out and the eyes twist round until they both 

 appear to be on the same side of the fish. Up to this time 

 the little fish swims about in the sea, but when it has 

 become a " flatfish " it sinks to the bottom.
