arrange  their  work  and  time  their  journey  as  to  reach  Manaos  about 
November  of  this  year.  Here  they  will  recive  large  shipments  of 
supplies  for  the  second  half  of  the  journey  and  send  home  the  col- 
lections already  made. 
According  to  present  plans  the  party  will  then  start  out  from 
Manaos  early  in  1922,  ascending  the  Rio  Negro  and  Rio  Uaupes  for 
the  purpose  of  exploring  and  collecting  among  the  upper  waters  of 
the  latter  river  and  in  some  of  the  valleys  and  ravines  along  the  east- 
ern side  of  the  Andes,  south  of  Bogota,  Colombia.  After  crossing 
the  mountains  to  Bogota,  they  will  finally  emerge  at  the  coast  at  Bar- 
ranquilla  for  their  return  journey.  . 
To  many  experienced  tropical  travelers  the  plans  for  the  second 
half  of  this  journey  from  Manaos  to  Bogota  appear  to  be  somewhat 
venturesome  and  impractical  because  the  party  may  be  expected  to  be 
very  much  exhausted  upon  their  arrival  at  Manaos.  Dr.  Rusby  is 
confident,  however,  they  will  all  arrive  at  Manaos  in  good  health  and, 
after  a  short  rest,  will  be  in  good  condition  to  undertake  the  second 
half  of  their  journey. 
Perhaps  no  other  expedition  that  has  gone  into  South  America 
has  ever  entered  the  tropics  so  well  protected  medically  against  pos- 
sibilities of  fevers,  skin  diseases  and  the  numerous  tropical  affec- 
tions. The  medical  supplies  which  the  expedition  is  taking  includes 
a  very  long  list  of  standard  pharmaceuticals  and  a  number  of  biolo- 
gical products,  which  are  of  even  greater  importance  under  the  cir- 
cumstances. These  include  great  quantities  of  antidysenteric  serum, 
for  the  prompt  treatment  of  cases  of  dysentery,  should  any  of  the 
members  of  the  party  contract  that  disease, — a  rather  unlikely  event 
if  all  the  members  make  the  proper  use  of  the  means  provided  for 
the  sterilization  of  the  dpnking  water.  Antipneumococcic  Serum  and 
antitetanus  serum  are  also  included  among  the  supplies.  Most  im- 
portant, however,  is  a  quantity  of  anti-snake-venom,  which  the  Mul- 
ford  Company  took  special  pains  to  prepare  for  Dr.  Rusfjy's  party 
and  which  they  are  supplying  to  them  in  small,  sterile,  hypodermic 
syringes,  ready  for  instant  use  when  occasion  requires. 
Members  of  the  party  have  further  protected  themselves 
against  disease  by  taking  certain  preventive  measures.  These  include 
the  well-known  measures  of  vaccination  against  smallpox  and  the 
prophylactic  inoculations  against  Typhoid  Fever,  the  effectiveness 
of  which  no  longer  remains  a  matter  of  doubt.    In  view  of  the
