Note : Dr. W. H. Dall's very useful pamphlet, " Instructions for 

 collecting Mullusks and other "useful hints for the Conchologist " was 

 published in 1892 as part G of Bulletin No. 39 of the U.S. National 

 Museum. It should be in the hands of every one taking up the study 

 of shells, and it contains in addition to full instructions for the collection 

 and preservation of specimens, figures of the necessary apparatus and a 

 list of the most useful text books &c.
