In regard to lobsters, we v;ere only able to succeed In 

 obtaining the hatc>iing of the eggso Before the first moulting, 

 that is to say, in 'ohe space of some days, the young crustaceans 

 perished in succession.? wo were not able to save a single one* 



In 1885, vre concerned ourselves only vfith the cod and the 

 lobsters Thanlcs to the experience acquired in the previous year, 

 the operations were carried on better and this time we succeeded 

 in rearing completely the young lobsters; vre were able to bring 

 them up to t?ie fifth period^ that is to say, beyond the fourth 

 stage period v/here, shedding the larval form and ceasing to float 

 in currents on the surface of the water as they do at first, they 

 make for the bottom in order to lead an adult existence -i
