in  Argentina.  It  was  seldom  indeed  that  he  failed  to  decipher 
these  prescriptions  and  to  give  the  information  requested. 
"  Professor  Hallberg  exerted  a  powerful  influence  over  his 
students,  and  this  influence  was  entirely  for  good;  especially  would 
he  urge  these  young  men  to  strive  for  the  attainment  of  pharma- 
ceutical ideals.  He  was  urgent  in  his  advice  that  they  join  the 
leading  pharmaceutical  organizations,  both  state  and  national,  and 
especially  would  he  use  every  argument  to  convince  them  of  the  need 
for  their  joining  the  American  Pharmaceutical  Association.  He 
secured  more  new  members  for  the  Chicago  Branch  than  any  other 
officer,  although  his  time  was  so  occupied  that  he  was  able  to  give 
but  very  little  of  it  to  this  cause. 
"  His  labors  were  most  unselfish,  and  it  is  not  surprising  that 
he  left  little  property.  His  interment  in  the  Ebert  lot  was  a  fitting 
recognition  of  the  close  personal  friendship  which  existed  between 
these  two  great  pharmaceutical  leaders  and  the  many  attributes 
which  they  possessed  in  common. 
"  Professor  Hallberg's  place  in  the  pharmaceutical  world  will 
be  exceedingly  difficult  to>  fill.  Few  men  possess  the  energy,  mental 
power,  and  the  physical  endurance  necessary  to  carry  the  amount 
of  work  that  he  carried  so  successfully  for  many  years."

Through  and  through  the  inspired  leaves, 
Ye  maggots,  make  your  windings  ; 
But  oh !  respect  his  lordship's  taste, 
And  spare  his  golden  bindings.

I  have  been  investigating  the  subject,  "  insects  that  destroy 
books,"  for  a  number  of  years ;  and  this  paper  is  simply  a  summary 
of  a  few  of  the  facts  that  I  have  discovered  and  collected.  No 
attempt  has  been  made  to  make  it  complete,  either  as  to  species  of 
insects,  or  subject  matter  under  any  particular  group.    These,  in  a
