4. The splendid series of specimens illustrative of 

 the natural history of Alaska, collected in 1865 to 1869 

 by Bishoif and the naturalists of the Western Union 

 Telegraph expedition. 



5. The Smithsonian collection of Crustacea, un- 

 doubtedly at that time the largest alcoholic collection 

 in the world. This filled over 10,000 jars containing 

 types of the species described by Prof. Dana and other 

 American authors, besides hundreds of new species,

 undescribed except in manuscripts, which were also lost.
