Mr. A. B. McCallum, B.A., read a paper on " Some 

 Pathological Growths in Lower Animals." 



Mr. Macallum exhibited a number of cat-fish affected with 

 cancer in various stages. 



In answer to questions from Mr. Livingston and Mr. 

 Rouse, as to whether there was any danger in eating the fish 

 so affected, 



Mr. Macallum replied that he did not think there would be 

 any danger at all. 



Mr. Macdougall called attention to the salmon disease, or 

 Saprolegnia, which affects not only salmon but perch and 

 eels. He had noticed the perch with large holes cut out of 

 the body, jump out of the water as if in pain. The internal 

 organs and the flesh were perfectly sound, and people ate of 

 them without injury The disease seemed to be the same as 

 the cancer in the fish exhibited by Mr. Macallum. 



Mr. Macallum said that the disease attacked all fish that 

 were not in a normal condition. To prevent it a normal 

 amount of food and aerated water were necessary. The 

 sewage in water in the old country caused it. 



Dr. Kennedy referred to the number of dead fish sometimes 

 seen floating in the bay, and asked the cause of it.
