 accomplished." His hatching-trough was similar, 

 strange to say, to that of Dom Pinchon. Full 

 directions are given for the removal of dead 

 spawn, and the care required by the living. His 

 is the first work upon pisciculture as a science. 

 Under the care of Lieut. Jacobi, fish farms were

 sen, and the fish produced became an important 

 article of commerce ; it is stated that the Queen
