appeared probable that the larvae would also become 

 entangled and eventually perish, I decided on the 

 following day to remove the parent lobsters to the 

 hatching tanks indoors. They were accordingly placed 

 one in each of the middle compartments of the tanks, and 

 hatching boxes were placed in the lowest compartments 

 in order to retain the newly-hatched larva?. Other boxes 

 were placed in the uppermost compartments in view of 

 rearing the larvae. Early in August several ' berried ' 

 lobsters with nearly-ripe eggs were brought in by fisher- 

 men and were added to our stock. I am unable to say 

 with any approach to accuracy how many larvae were 

 hatched, but 2,550 in the first and second stages, and 80 

 in the ' lobsterling ' stage were set free in the sea as

A number of the larvae in the early stages, and all 

 the lobsterlings, were set free inside the ruined landing 

 pier at the base of the breakwater, where there is 

 abundance of shelter from predaceous fishes and where 

 young lobsters are known to occur. Of the remaining 

 young larvae a number were liberated, from the 

 s,y, ' Ladybird,' along the northern side of the Calf
