themselves after they hare been taken from their 

 long imprisonment in the ice. They have been 

 taken every care of by Tennant, the keeper of the 

 Aquarium-house, Zoological Gardens, who reports 

 as follows : — 



" ' On March 25th, I received six salmon eggs 

 which had been fiffy-nine days in the refrigerator 

 of the Wenham Lake Ice Company, ia the Strand. 



" ' On April 14th, two of these hatched out, the 

 other four were bad. 



" ' On March 25th, I received seventy-five eggs, 

 which had been buried deep in a block of ice in 

 the ice-weUs fifty-nine days. These began to 

 hatch out on the 18th of April, and finished hatch- 

 ing on the 21st of April. Out of this lot fifty-two 

 eggs were bad, but the remaining twenty-three 

 hatched out properly, and are now strong and 

 lively, and still remain in the place where they 

 were bom. 



" ' On April 17th, the day of Mr. Buckland's 

 lecture, Mr. Youl gave me a box which contained 

 thirty-five salmon eggs, that had been buried in 

 the ice-weUs ninety days. I placed them in the 

 hatching-box next morning, at a temperature of 

 50°; five of the eggs are bad, but in most of the 

 others the eyes are ftdly developed. — J. Tennant,. 

 Fish-house, Zoological Gardens, April 22nd.' 



" On May 9th, Tennant reports of these eggs : 

 some began to hatch out on the 28th of April, 

 and finished hatching May 6th — twenty-six 

 young ones and nine bad eggs. The young fish 

 are not so large as those whose incubation has not 

 been retarded by freezing, but still they are very 

 lively little fish.
