The  method  of  mailing  these  publications,  of  checking  the  ac- 
knowledgments, and  of  keeping  the  list  correct  as  to  changed  and  new 
addresses  has  been  very  satisfactory,  and  it  is  rare  that  complaints 
are  received  of  improper  direction  or  failure  to  receive  the  publications 
promptly.  Such  tardiness  or  neglect  in  acknowledging  the  receipt 
of  these  publications  appeared  to  exist  the  first  of  the  year  that  it  was 
found  necessary  to  send  out  a  special  circular  letter  reminding  those 
to  whom  the  publications  had  been  sent  of  the  importance  of  signing 
and  returning  the  acknowledgments  enclosed  in  the  several  publica- 
tions. This  not  only  enabled  the  institution  to  account  for  the  dis- 
tribution of  publications,  but  was  the  indirect  means  of  correcting
