and they are then conveyed to the hatchery. Mr. Neilsen anticipates 

 that he will be able to hatch 70 to 90 per cent, of the ova^ instead of 50 

 per cent, as at present^ by this improved method. Such results 

 have been recently attained at Flodevig hatchery in Norway, where, 

 partly through Mr. Neilsen^s recommendation, it was adopted two 

 years ago. . . . The total number of lobster ova obtained 

 was 18,505,600 ; and of these 10,274,300 were hatched and planted.'^ 

 This is the most extensive hatching of sea fish yet accomplished. —
