unforeseen difficulty occurs, to increase this stock, and to 

 devote more attention to the hatching and rearing 1 of the 

 sole during next season. 



''It is a pleasure to report to the Board that Mr. 

 Chadwick, the curator; Mr. T. N. Cregeen, the assistant; 

 and the boy, Willie Christian, have been most energetic 

 and efficient in their several spheres of work ; and I 

 should like to add that Mr. Chadwick and I feel much 

 indebted to the secretary to the Board, Mr. R. Okell, 

 F.L.S., for his valuable help and for the large amount of 

 attention he gives to the affairs of the institution. 



I have now to add that during last summer, after the 

 above Report had been issued, a curious epidemic,* caused 

 by a fungus which invades the liver and kidneys, attacked 

 the fish in the pond, and resulted in considerable mortality 

 of both plaice and soles. The fish that survived were set 

 free, as it was thought best under the circumstances to 

 clear out the pond completely, and start this season with 

 a fresh stock of fish free from infection. 



" (Signed) W. A. Herdman."
