ISAAC LEA DEPARTMENT. 
[Conducted in the interest of the Isaac Lea Conchological Chapter of the Agassiz Associa- 
tion by its General Secretary, Mrs. M. Burton Williamson. } 
Members of our Chapter who have not received the Transactions 
will be glad to learn that before many weeks the volume will have 
gone the rounds of the chapter. With two or three exceptions, 
members have promptly forwarded the volume after retaining it but 
one week, and the General Secretary desires to thank members for 
their promptness in notifying her when forwarding the reports.

[From the report of Mr. A. H. Gardner. From the Transactions of the Isaac Lea 
Chapter for 1895.] 
Not the smallest object to the collector and conchologist is sym- 
metry in thearrangement of the cabinet. Nothing can appear worse 
than an untidy heterogenous array of specimens, which too frequently 
reflects the spirit of its author.
