instruction  should  fit  him  not  only  to  differentiate  organized  forms 
but  other  characteristic  elements,  such  as  fat  crystals,  mineral 
crystals,  and  the  like. 
After  such  a  course,  he  should  be  able  not  only  to  undertake 
investigations  in  physiological  or  plant  chemistry  but  also*  the 
laboratory  work  of  an  official  food  department  or  a  custom  house, 
a  flour  mill,  a  brewery,  a  sugar  refinery,  a  candy  works,  a  fruit 
cannery,  a  drug  mill,  a  textile  mill,  a  paper  mill,  etc. 
It  is  my  firm  belief  that  courses  similar  to  that  outlined  should  • 
be  conducted  in  all  our  leading  universities  and  schools  of  tech- 
nology, and  the  student  should  be  taught  the  use  of  the  microscope 
in  conjunction  with  the  balance  in  solving  the  analytical  problems 
which  every  day  become  more  numerous  and  intricate.

AN  HISTORICAL  MEDICAL  EXHIBITION  IN  LONDON. 
For  the  first  time  in  21  years  the  International  Medical  Congress 
will  meet  in  London  in  the  summer  of  19 13,  and,  in  this  connection, 
an  exhibition  of  rare  and  curious  objects  relating  to  Medicine, 
Chemistry,  Pharmacy  and  the  allied  sciences  is  being  organized  by 
Mr.  Henry  S.  Wellcome.  The  response  to  the  appeal  for  loans  has 
been  most  successful,  with  the  result  that  probably  one  of  the  most 
interesting  collections  of  historical  medical  objects  ever  gathered 
together  will  be  on  exhibition  during  the  meeting  of  the  Congress. 
Among  other  interesting  sections  is  one  including  the  medical 
deities  of  savage,  barbaric  and  other  primitive  peoples.  Through 
the  kindness  of  friends,  specimens  of  these  have  been  forwarded 
from  all  parts  of  the  globe,  but  there  are  still  many  gaps  to  be 
filled,  and  those  who  possess  such  objects,  and  would  be  willing  to 
loan  them,  should  communicate  with  the  Secretary  of  the  Exhibition, 
whose  address  is  given  below.  - 
Amulets,  talismans  and  charms  connected  with  the  art  of  healing 
will  also  form  another  prominent  feature  and  any  loans  of  this 
description  would  be  welcomed. 
In  the  section  of  surgery,  an  endeavor  will  be  made  to  trace 
the  evolution  and  development  of  the  chief  instruments  in  use  at 
the  present  day,  and  it  is  desired  to  accumulate  specimens  of  instru-
