subjects  which  qualifies  him  to  supplement  the  work  of  the  surgeon 
on  closely  co-related  lines,  especially  in  chemistry,  bacteriology,  clin- 
ical laboratory  investigation,  roentgenography,  in  assaying  drugs, 
foods  and  other  supplies,  in  analyzing  human  excretions,  blood, 
sputum,  etc.,  in  testing  drinking  water,  food  products,  soils,  as  well 
as  in  toxicology  and  drug  compounding  and  dispensing. 
"  In  any  event,  the  services  he  could  render  are  numerous,  among 
them  note  taking,  examinations,  diagnoses  of  minor  ailments,  prompt 
clinical  laboratory  findings,  and  opinions  would  be  invaluable.  He 
could  act  as  expert  anaesthetist,  as  assistant  in  many  operative  di- 
rections, and  could  apply  the  less  complicated  dressings  and  plaster 
casts,  and  variously  hold  up  the  hands  of  the  surgeon.  He  could 
apply  much  of  the  detail  of  medical  advice  in  hygiene  and  dietetics. 
The  whole  subject  of  sanitation  falls  naturally  within  his  purview, 
the  precautions  of  hygiene,  of  preventive  medicine  generally,  also 
applied  bacteriology,  disinfection  and  other  prophylactic  necessities 
of  modern  warfare. 
"Justice  to  the  medical  men  of  the  army  and  navy  demands 
that  they  be  given  adequate  assistance  in  the  prosecution  of  their 
work,  and  the  suggestion  that  skilled  pharmacists  be  given  a  com- 
missioned rank  in  the  army  and  navy,  and  that  they  be  made,  also, 
medical  and  surgical  assistants,  will  meet,  we  believe,  not  only  with 
the  unqualified  approval  of  the  medical  profession  generally,  but 
with  that  of  the  public  whose  interests  are  still  further  protected." 
Preparation  of  Dichloramin  T. — Chlorinated  lime  of  phar- 
macopoeial  strength — from  350  to  400  grams — is  well  agitated  with 
two  liters  of  water  for  half  an  hour.  When  sedimentation  has 
taken  place  the  supernatant  fluid  is  siphoned  off  and  the  remainder 
filtered.  Powdered  toluene-parasulphonamid,  75  grams — the  crude 
product  may  be  used — is  dissolved  in  the  chlorine  solution.  If 
necessary  the  resulting  solution  is  then  filtered,  placed  in  a  separat- 
ing funnel,  and  made  acid  by  gradually  adding  100  mils  of  acetic 
acid.  100  mils  of  chloroform  is  then  added  to  extract  the  dichlora- 
min. After  frequent  vigorous  agitation  the  chloroform  layer  is 
drawn  off,  dried  over  calcium  chloride,  filtered,  and  allowed  to 
evaporate  in  the  air.  The  residue  then  obtained  is  powdered  and 
dried  in  vacuo.  If  necessary  it  may  be  purified  by  recrystallization. 
Generally  it  is  not  necessary. 
This  chemical  is  stated  to  be  powerfully  germicidal  and  is  gen- 
erally used  dissolved  in  a  mixture  of  Eucalyptol  U.  S.  P.,  which
