Total loss of hatched fish to date 996, or nine per cent of total 

 number of eggs, or about fifteen per cent of impregnated. 



The above are all that are far enough advanced to tell the pro- 

 bable loss up to time of commencing to feed. I think the above 

 shows the loss to be principally of weak fish. There were some 

 deformities which were taken out and counted with the dead. 



Temperature of water forty-eight and forty-nine. Some fungus 

 grew on the wood work of the grills. My boxes are all charred, but 

 according to Slack " doing no possible harm." ' (See page ninety-one 

 of his book.) 



I give below the figures of all that are hatched up to date.

 eight per cent impregnated. Unimpregnated 5,725.
