ISAAC LEA DEPARTMENT. 



[Conducted in the int. n-t of tin- Isaac Lea Couchologii-al Chapter of tliu 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. 



A CHAPTER ON METHODS. 



[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 the arrangement of the cabinet. Nothing can appear worse 

 than an untidy heterogenous array of specimens, which too frequently 

 reflects the spirit of its author.
