 fish and other marine animals.

 sonian Institution to make amicable arrangements with the various 

 Departments of the Government by whict to avoid duplication of effort 

 in material. This has been shown in many ways, as in the arrange-

 spondence and labors which had been so effective in the hands of the 

 Smithsonian Institution for nearly twenty-five years.
