5.-TRANSPE ANTING LOBSTERS TO THE CHESAPEAKE -EXPER- 

 IMENTS UPON THE TEMPERATVKE THEY CAN ENDURE. 



By Lieut. W. JK. WOOD, U. S. N. 



Oetober 18 I procured from Mr. E. G. Blackford, in New York, 125 

 live lobsters of small and medium size, many of them being females 

 with a full supply of eggs. They were placed in a tank through whieh 

 salt water was circulated, but quite a number died the first few hours, 

 being probably in poor condition when received from the market. On 

 our arrival in the Chesapeake, I deposited 63 in good condition and trust 

 they may be heard from in the future. They were deposited off Block 

 River light at 11.30 p. in., October 19. 



I tried the following experiments in this connection by means of 

 the ice machine. In a cask containing salt water and maintained at a 

 temperature of from 34° to 36° F. I placed 5 lobsters. At the end of 

 twenty four hours 3 were dead and 2 alive and in apparent good condi- 

 tion. 



In the cold cheist, kept at a temperature of from 34° to 38° R, 5 

 others were put. At the end of twenty-four hours 2 were dead, 2 iu 

 excellent condition, and 1 rather weak. The 3 latter were allowed to 

 remain another twenty-four hours, or forty-eight hours in all. The 

 weak one was then dead and the other two in pretty good condition
