"The ease with xvhich the voung lobsters in the pools of Con- 

 carneau multiply and develop is one sure guarantee that in our 

 coasts one should easily find suitable localities for crt ating

 they should be enough advanced in age to resist for the mo >t part 

 the causes of destruction v/hicli menace them incessantly* -Von 

 what vre have seen since our first visit to Concarneau (July 1865), 

 that is to say, the pools literally black "v.ith smr.ll lobstei s

According to Captain 'Dannevig, "shortly after liatcjiing from 

 the eggs J, the ,/oung lobsters vj-hose shape is very different from 

 that of the adults, measiore about nine millimeters long* Tiiey are 

 considered very promptly as the Mysis formo They are extremely 

 voracious and seek to devoijr each other, principally during the 

 first days vrhich follov; hatching* One is able to feed 1;hem with 

 the flesh of crushed crabo 



"At about eight days, after the second moult, they reach 12 

 millimeters in length and after tlie sixteenth day, v/hen the third 

 moult is effected, they are about 15 millimeters. 



"At the age of four or five weeks, they undergo a foui'th 

 m.ou''t in which they lose their swii.aning organs, tjiat is to say, 

 the double appendages of the lii:ibs, and they enter into v.'-hat Sars 

 calls, their fifbh periods Fi'om siTimjr.ers , they become walkers until 

 the end of their existence.
