This valuable synopsis contains numerous descriptions of dis- 

 eases affecting fishes of the United States some of whicli have 

 been introduced into Europe, and also European fishes which have 

 been acclimated in our country. The book contains chapters on 

 furunculosis or ulcer disease, the red plague of the carp-like fishes, 

 the red plague of the eel, the salmon pest, the yellow plague ni 

 the redeye, "or so-ealled pearl roacli (d" New York City lakes, the 

 spot disease of the 1)r(iiik tmut, tuberculnsis in lishts. smallpnx in 

 the carp, together with interesting accounts of the diseases of the 

 skin, the gills, the intestines, the liver, swim-bladder, and the 

 \arious viscera and organs of the bodj', the parasites and bacterial 

 affections of many species well known to us as fish culturists. 

 The most striking difficulty encountered in the use of this work 

 arises from the slight knowledge available concerning the origin 

 and treatment of the diseases referred to.
