EPIDEMIC AT development and propagation of the fungus in the moat, thi3 could not he 

 IGHTHAM. advanced as a reason for the appearance of the disease in the upper pond, 

 which was fed by an uncontaminated stream. Neither could diseased fish 

 from the moat find their way to the upper pond so as to infect the fish there, 

 as there is not only a clear fall of between three and four feet between the moat 

 and the stews, but one of about five feet between the stews and the upper 

 pond, thus presenting obstacles such as the fish living in these waters could 

 not surmount. 



In conclusion, I feel convinced that the so-called salmon disease is the 

 fungus itself, and that no structural disturbance in the fish is necessary to 

 cause fungus attack ; that this appears to me to have been abundantly proved 

 by the b'O specimens which I. have dissected and examined ; that it is useless 

 to look for more information on the origin and cause of fungus epidemic, 

 from the carcases of salmon or other fish affected with the fungus ; that the 

 origin and cure or prevention of the plague must be sought for in the life 

 history of the plant, which is more the work of the botanist than the 

 anatomist.
