the author in the early part of last year. Thirty-seven 

 gardens in all were visited, in France, Holland, Denmark, 

 Belgium, Germany, Russia, Hungary, Austria, Switzerland, 

 and the British Islands, and a more or less detailed account 

 is given of each, enriched by photographic illustrations. 

 There are a good many slips and misprints in the letter- 

 press, but Mr. Peel has produced a very readable volume, 

 which we are sure will be much appreciated. The Zoological 

 Garden of Berlin is, no doubt correctly, pronounced to be 

 the best on the Continent, although there must be some 

 error in the statement on p. 106 that it contains " 25,000 

 living creatures," representing 12,000 mammals and birds. 

 Whether it is " well ahead of our London Garden " is, 

 perhaps, a matter of opinion. 



In a second edition we hope that the author will correct 

 numerous misprints in the scientific names of the animals and 

 other mistakes. He should also extend the sphere of his 

 observations, and visit the gardens in the United States, 

 at New York, Philadelphia, and Washington, not to mention 

 those at Cairo, Pretoria, and Calcutta. 



60. Preble on the Biology of Hudson Bay. 



[A Biological Investigation of the Hudson Bay Region. By Edward 

 A. Preble. North- American Fauna, No. 22. 8vo. Washington, 1902. 

 140 pp., Id pis., 1 map.] 



Since the days of the early pioneers, who sent many speci- 

 mens for determination to Britain, singularly little advance 

 has been made in our knowledge of the fauna of Hudson 

 Bay, and the U.S. biologists have consequently found con- 

 siderable difficulty in determining the status of many species 

 through want of sufficient material for comparison. The 

 outcome has been an expedition sent by the Biological 

 Survey to the western shores of the Bay in 1900, in charge 

 of Mr. E. A. Preble, who furnishes a very full account of 

 tiie districts traversed, with details of the " life zones " and 

 botany, while he has not forgotten to sketch the work of 

 previous explorers and to add a bibliography. The Report 

 confines itself almost entirely to the province of Keewatin, in
