APPENDIX TO PAPER ON THE FUNGUS OF 

 SALMON DISEASE. 



In further confirmation of my opinion on the influence of temperature, I this 

 year kept a regular daily observation of the temperature of the water from the 

 30th of March till the 10th May— that Js, from a time before the usual period of the 

 outbreak of the disease, and continuing until the salmon were found dying of the 

 disease in the usual way. 



I also kept some notes of the results of the angling during the same period, and had 

 opportunities of examining a few of the fish that were caught by the rod, and others 

 that were caught by nets in the river, every opportunity being afforded me of so doing, 

 though I regret that owing to my being very much occupied at other work, I was not 

 able to take full advantage of my chances. 



The following are the temperature observations, as taken daily : —
