ma^- be used. The receptacle, whatever it may be, should be suspended, 

 iu order to avoid the disturbance of its contents by the incessant rolling 

 of the vessel ; such motion being prejudicial to the welfare of the fishes. 

 The fishes should also be fed, and a supply of suitable plants should 

 therefore accompany them. We append a translation of the specific 

 instructions of M. Coste, from whom, indeed, have been derived the 

 hints above offered. 



" 1. Very young fishes should be selected. 



*'2. These fishes should be distributed among several receptacles. 



"3. Care should be taken uot to crowd too many together in one 

 receptacle. 



" -4. The water should be renewed partially or entirely whenever it 

 becomes necessary. 



" 5. It should also be aerated from time to time. 



" 6. The fishes should be fed whenever they shall seem to require it. 



" 7. The remains from the food which has been given to the fishes 

 should be carefully taken up from the bottom of the receptacle, and 

 removed within eight hours after feeding ; the dejections and other 

 impurities which would injure the water should be removed. 



" 8. Finally, the several receptacles should be kept iu different places 

 and under various conditions."
