and  heavy  boat  with  its  fore  part  roofed 
over;  it  is  here  called  a  canoa.  We  left  a 
6  p.  m.  but  stopped  soon  because  of  a 
strong  headwind  and  only  took  to  the  oars 
at  9  o'clock. 
3  X,  We  passed  PÃO  DE  ASSUCAR 
and  many  other  places.  The  wind  was  always 
very  strong  and  unfavourable.  We  observed 
no  shells,  no  game  and  no  fish.  The  night 
was  spent  on  board. 
4  X.  We  cruised  all  day  with  an  unfa¬ 
vourable  wind  and  arrived  at  night  only,  in 
PROPRIÁ,  where  we  landed. 
5  X.  In  the  town  there  is  a  pond,  now 
half  filled  up  by  order  of  the  Federal  Go¬ 
vernment,  where  we  found  many  Plano rbis 
centimetralis,  containing  two  species  oiCerca- 
riae  with  forked  tail,  one  of  them  with 
eyes  and  the  other  showing  a  very  deeply 
divided  tail.  There  was  a  third  Cercaría 
with  a  single  and  very  long  tail  found  in  cen¬ 
timetralis  which  I  collected  in  the  Lagoa  da 
Pedrinha  below  the  town. 
6  X.  We  went  by  canoe  to  the  Lagoa 
de  Oity,  above  the  town,  where,  as  in  the 
one  just  mentioned,  there  is  an  extensive 
culture  of  rice.  We  found  two  species  of 
Bivalves  but  no  Planorbis.  We  collected 
several  Paederus,  here  called  potó. 
7  X.  With  Dr.  MOACYR  LEITE,  I  vi¬ 
sited  the  hospital  and  saw  a  patient  with 
cirrhosis  of  the  liver.  The  stools  contained  a 
large  number  of  Schistosomum  eggs,  which 
were  buried  in  mucus  and  had  a  white  shell. 
The  patient  confessed  to  a  taste  for  strong 
drinks,  so  that  the  influence  of  the  parasites 
was  uncertain.  -  Afterwards  we  took  the  train 
to  Aracaju.  During  the  journey  I  found  the 
first  Planorbis  oliváceas  in  Murta,  near  to  a 
tributary  of  the  Rio  Japaritubá. 
8  X.  The  secretary  of  the  Interior,  to 
whom  we  had  a  letter  of  introduction, 
received  us  very  well  and  attended  to  all 
our  wishes.  We  collected  many  olivaceus 
near  to  the  school  and  in  a  pond  called 
Lagoa  da  Egoa.  They  contained  Tetracotylus 
and  Cercariae  with  simple  tail,  but  none  of 
Schistosomum  mansoni. 
9  X.  We  went  by  steam-launch  to  La- 
rangeiras  where  at  that  time,  Planorbis 
were  rare  and  uninfected,  but  we  found  evi¬ 
dence  of  infection  by  Schistosomum  man¬ 
soni  in  man. 
10  X.  In  the  hospital,  we  saw  many 
cases  of  ulcers,  some  of  them  due  to  tertiary 
syphilis.  Stones  in  the  bladder  were  compa¬ 
ratively  frequent.  Afterwards,  we  searched 
several  pools  unsuccessfully  and  examined 
specimens,  some  of  which  contained  eggs  of 
Schistosomum. 
11  X.  We  went  on  horse  back  to  the 
Colonia  Agrícola ,  accompanied  by  its  director, 
Mr.  TRAVASSOS.  The  road  crosses 
dunes  and  plains  of  pure  sand  with  a  very 
interesting  vegetation.  In  the  river  POXY-M1- 
RIM,  there  were  some  Planorbis  which  se¬ 
emed  to  be  small  olivaceus.  They  contained 
three  kinds  of  Cercariae  with  forked  tail,  one 
of  them  belonging  to  Schistosomum  manso¬ 
ni  and  the  others  like  those  of  Propríá. 
With  great  difficulty  we  obtained  a  few  spe¬ 
cimens  of  Triatoma  rubrofascicita  in  a  house 
where  they  had  been  discovered  before. 
12  X.  A  large  number  of  examinations, 
made  in  Aracaju,  yielded  a  proportion  of 
27  to  28  %  showing  eggs  with  lateral 
spine.  They  were  most  numerous  in  the 
specimens  obtained  from  a  girl  come  from 
Capella.  I  went  to  the  prison,  where  I  chose 
twenty  men  from  different  regions,  so  as 
to  obtain  some  information  on  the  distri¬ 
bution  of  the  parasite  in  this  country. 
13  X.  In  the  hospi;al,  we  examined  the 
girl  from  Capella,  and  found  her  spleen  and 
liver  small.  Her  mother  infected  in  lesser 
degree  had  a  large  spleen  and  a  small  liver.  We 
examined  more  pools  and  ponds,  near  to  the 
hospital,  which  is  rather  far  from  the  town. 
Only  in  the  Lagoa  da  Telha  did  we  find 
Planorbis  olivaceus,  some  of  the  specimens 
being  infected  with  the  first  stages  of  Schis¬ 
tosomum  mansoni.  Examining  22  specimens 
mostly  sent  from  the  prison,  the  eggs  with  la¬ 
teral  spine  werefound  seven  times.  Taking  into 
account  that  recent  or  slight  infections  may 
escape  a  somewhat  superficial  examination, 
the  average  proportion  of  infected  people 
among  the  lower  classes  is  probably  more
