To ensure that this array of contributors shall work on the same 

 dines, a number of rules have been drawn up, which will no doubt be 

 rigidly enforced by the editors. We have already commented upon 

 the rules of nomenclature that are to be followed. For the denotation 

 of colours, Saccardo's " Chromotaxia " is to be employed, except in 

 such cases as more special terms may be advisable, e.g., for the birds. 

 The abbreviations of authors' names will follow that cryptographic 

 production known as the Berlin Author-list. German is the language 

 to be used, though English, French, or Latin may exceptionally be 

 employed. German would be as good as any other language if only 

 the Germans would use the Graeco-latin technical terms that are used 

 by all the other zoologists of the world ; but if the contributors to 

 Das Tierreich are going to continue to use ordinary German words, 

 or, still worse, compound German words such as are given in no 

 dictionary, for the technical terms of the science, then the adoption of 

 this language will render the work far from popular among zoologists 

 of other countries, and will materially detract from its value and its 

 pecuniary success. 



The size of the page to be employed is about 26 by 17 centim. 

 {Lexicon 8vo). The paper has a rather smooth surface, is stated to 

 be pure, and weighs eight sheets to the pound. .The type is small 

 pica for the diagnoses, and long primer (the type in which this article 

 is set) for subsidiary information ; it is set solid throughout. Hair- 

 spacing, italics, and clarendon are used for distinctive purposes. 

 Seeing that this work will inevitably run to an enormous size, and
