IV. Special Publications. 



There was issued during the year a special publication in the form of the 

 Smithsonian Contributions to Knowledge, but it was not included in that series 

 since only a limited number of copies of the accompanying plate were available. 

 The work is entitled : 



1694. Remarks on the Type of the Fossil Cetacean Agorophius pygmaeus 

 (Miiller). By Frederick W. True. City of Washington: Published by the 

 Smithsonian Institution, 1907. Quarto. Pages 8, with 1 plate. 



The author in the first paragraph of the work says : 



Somewhat more than fifty years ago the Smithsonian Institution, then 

 recently founded, undertook the publication of a number of memoirs by Prof. 

 Louis Agassiz, and prepared some lithographic plates to accompany them. 

 Before the work had proceeded very far, Professor Agassiz made other arrange- 

 ments for the publication of .his writings and the plates were never issued. One 

 of these unpublished plates represents the type specimen of a very remarkable 

 species of fossil cetacean, now known as Agorophius pygmaeus (Miiller), and 

 on account of circumstances which are detailed below it has been thought 

 desirable to issue it, with a brief explanation as to its importance. 



As a special publication, No. 1722, there was printed an octavo pamphlet of 

 38 pages entitled " Classified List of Smithsonian Publications available for 

 Distribution April, 1907." 



For general distribution to correspondents there was published, without bear- 

 ing a serial number, a duodecimo pamphlet of six pages entitled " The Smith- 

 sonian Institution, at Washington, for the Increase and Diffusion of Knowledge 

 among Men." This pamphlet gives a brief description of the functions of the 

 Institution and its branches for the general information of the public.
