attracted marked attention from naturalists. It forms an octavo of 51 

 pages. 



Bulletin No. 18 is a pamphlet of 278 pages, and is entitled "Exhibit of 

 the fisheries and fish culture of the United States of America, made at 

 Berlin in 1880, prepared under the direction of G. Brown Goode, deputy 

 commissioner." 



This work is a catalogue of the articles brought together by the United 

 States Fish Commission for exhibition at the International Fishery Ex- 

 hibition held in Berlin in April, May, and June, 1880. An account of 

 this exhibition and of the display made by the United States, with the 

 awards to exhibitors, will be found in another place in this report. 



The bulletin or catalogue was used as the official list or guide to the 

 American i^art of the exhibition, was republished in Berlin, translated 

 into German, and on account of its extent, classification, detail, and ac- 

 curacy, elicited much j)raise. 



The work is arranged under six sections or heads, viz : 



A. Aquatic animals and plants of North America beneficial or in- 

 jurious to man. 



B. Fishing-grounds of North America. 

 O. Means of pursuit and capture. 



D. Methods of preparation. 



E. Animal products and their applications. 



F. Research, protection, and culture. 



Under each of these sections, subdivisions are made for the purpose 

 of systematic classification.
