 positions the salt bath may first be tried. One 

 way is to make a solution so strong that it is bit- 

 ter to the taste, and leave the fish in it until 

 it turns on its side. Then transfer it quickly 

 to a pan or bucket containing fresh water. The 

 fish will soon revive and perhaps exhibit some 

 signs of animation, on the disappearance of 

 which replace it in the salt water. Repeat the 

 operation a number of times, after which it may 

 be placed in the hospital tank for a day or so, 

 or returned to the aquarium. This treatment 

 is but for fungus. The temperature of the salt 

 water must not be lower than the fresh to which 

 it has been accustomed. Another course is to 

 make a salt-solution so mild as to be scarcely 

 detected by the taste, and put the fish in it for 

 several days. The vessel containing the mild 

 salt-solution should be set in a well ventilated, 

 light and warm place, and the patient shoiald be 

 given no food, and, after feeding is resumed, 

 but very small quantities. Salt is generally ef-
