I believe that tlie growth indicated iu these experiments repre- 

 sents fairly well the growth under natural conditions. The cars 

 were of good size, and many species of marine animals and plants 

 thrived on the inside. The lobsters were fed nearly every day. 



One of the noticeable features, as shown iu the measurements, 

 is the great variation iu the rate of growth among the specimens 

 iu each of the cars. The age of all the specimens in any one car 

 was the same, but after three months the difference in size was so 

 great that some si)ecimens were not longer than the claws of others. 

 There were in all the cars, except the first (set 1) a number of 

 specimens which retained the two white spots on the back of the 



The (♦) in the tables denotes that this specimen has tlie wliite spots on tlie first ring of tiie 

 abdomen, a character of the fiftli and sixtli stages.
