At^ six weeks old this color begins to change, the fish gradually turning darker and then assuming the rich yellow, the back and fins sometimes becoming black. The perfection and rapidity of the coloring process depend upon several causes, foremost among which is the proper selection of specimens from which to breed.

Yours, with inquiries regarding the

conclusions reached in the study of the lobster,

While unavoidable delay in the hand drawings prevents placing the complete matter in your hands, it is quite possible to give you in a few words a general idea of the results and their bearings, such as will no doubt sufficiently answer your questions. According to the arrangements made, some of the eggs from berried lobsters kept for the purpose were sent me at regular intervals through an entire year. These eggs were at once examined to note their progress in development, and they were then preserved by various methods for future studies and comparisons. After their young were hatched the females themselves were dissected, to observe the condition of their ovaries, and to deis at

when another lot of eggs might have been expected from them. As our work began in midwinter it was necessary to follow certain specimens up to the hatching, and then to take others to complete the termine the time

The development of the embryo in eggs laid on August 7 or 8 was so rapid that on September 3 the eyes were visible as thin crescent-shaped spots.
