PREFACE. 
j:j lfty y ears a o° Europe had but one Zoological Garden, the 
^ “Jardin des Plantes” in Paris, Prance. In 1S29 the second 
institution of the kind was established in London, which 
can now be regarded as the model Zoological Garden, at least 
so far as the variety and value of its animals are concerned, 
lo-day we find Gardens in almost every important City in the 
Old World. At present there are but two Zoological Gardens 
in the United States, one at Philadelphia and the Cincinnati 
Garden. St. Louis will soon have its Zoo-Zoo and before many 
years have passed other Cities will undoubtedly move in the same 
direction. The aim of all Zoological Gardens, is in the first place 
Education; in the second, Recreation and Amusement, and the 
Cincinnati Garden makes no exception to this rule. The Zoological 
Society of Cincinnati, to which alone the Garden owes its 
existence, was organized in 1873 and is the direct outgrowth of 
the Acclimatization Society. In the early part of 1S73, Mr. 
Andrew Erkenbrecher, then President of the last named organi¬ 
zation directed the Secretary of that body to correspond with the 
celebrated Naturalist, Dr. A. E. Brehm, with a view of obtaining 
an estimate of the probable cost of a Zoological Garden established 
upon European Models, requesting statistics in regard to those 
already established in Europe, and all other available information 
pertinent to the subject.
