Important donations of West African species have been made from 

 fine to time by Mr. A. Ridyard, Chief Engineer of the 8.S. "Niger."' 



From year lo year specimens of the Rainbow Trout {Salmo irideus) 

 have been hatched and reared in the small Fish Hatchery in the 

 Aquarium. In April last Mr. Clubb stripped two of the Rainbow 

 Trout living in the Aquarium, successfully fertilizing the eggs, which 

 in due time hatched out, and some of the young are now upwards of 

 five inches in length. 



By the kind co-operation of the Sanitary Sub-Committee and of 

 the City Engineer, arrangements have been made for the periodical 

 supply of sea water for the salt water tanks, from the Mersey Estuary, 

 by means of the Corporation barge " Beta." This is a great improve- 

 ment on the filtered water from the salt water baths, and we are now 

 able to keep marine forms alive in our tanks for considerable periods. 

 Our thanks are due to Captain Griffiths of the "Beta, ' who has been 

 indefatigable not only in supplying us with water when required, but 

 also in obtaining for us many specimens of interest, It is hoped to 

 cany on dredging operations whereby specimens of marine life 

 will be obtained for our British Collection.
