THE BOOK SHELF 177 



Goldfish Varieties and Tropical Aquarium Fishes by Wm. T. Innes — Innes & 

 Sons, Philadelphia. 80, 246 pp. Illustrated. 



While this is a book about aquarium fishes, it contains a vast amount of 

 practical information of value to a teacher or to one who has an aquarium of 

 any sort. Such chapter headings as "The Freshwater Aquarium," "Terraria 

 and Aqua-Terraria," "Fish Foods," "The Microscope in Aquarium Work," 

 "Plants for the Aquarium and Pond" indicate sources of much good and useful 

 freshwater biology, while the last three chapters on "The Construction of 

 Aquaria, Tanks, etc.", "Aquarium Appliances," and "Forty Dont's" are 

 exceedingly practical. All are very clear in statement and excellently illus- 

 trated. It is a beautiful and helpful book that ought to find a place on the 

 shelves of all good school libraries. J. G. X.
