66 
were  other  land  and  fresh  water  shells  but 
no  larvae  of  Mansonia. 
4-6  IX.  I  visited  a  new  asylum  for  poor 
people  and  made  several  excursions  without 
finding  any  Planorbis.  Only  in  the  Rio  Ja- 
guarib  ■  did  we  collect  a  few  centimetralis  and 
the  common  black  Physa.  The  rest  of  the 
time  was  spent  in  the  hospitals,  where  se¬ 
veral  cases  of  Schistosomum  were  disco¬ 
vered. 
7  IX.  We  took  the  train  to  Pernambuco. 
While  Dr.  PENNA  with  his  servant  went  on 
to  Pau  d’Alho,  Dr.  LUTZ  and  the  other 
servant  stopped  in  Floresta  dos  Leões  and 
walked  on  the  line  to  Lagoa  do  Carro. 
On  this  side  of  the  station,  there  is  a  brick- 
factory  where  they  found  many  Planorbis  cul- 
i ratas  and  some  centimetralis.  In  the  large 
pond,  which  gave  its  name  to  the  place, 
there  were  no  Planorbis.  Dr.  PENNA  also, 
found  centimetralis  in  Pau  d'Alho  ;  besides 
the  normal  type,  there  was  an  orange  colored 
variety.  He  also  verified  the  existence  of 
Triatoma  rubrofasciata.  From  Lagoa  do  Carro 
we  took  the  train  to  Limoeiro. 
8  IX.  In  the  Rio  Capybaribe,  I  found 
numerous  Planorbis  centimetralis  and  Planor¬ 
bis  cultratus ,  in  some  ponds  covered  with 
Pistia  stratiotes.  They  also  contained  larvae 
and  nymphae  of  Taeniorhynchus  pseudo- 
mansonia. 
9  IX.  In  Limoeiro  we  found  many  PI. 
centimetralis.  Excrements  found  on  the  bank  of 
the  Rio  Capybaribe  were  examined  and  two 
of  them  showed  eggs  of  Sch.  mansoni. 
10  IX.  We  took  an  early  train  and  spent 
the  day  and  the  night  in  Campo  Grande, 
where  we  collected  PI.  centimetralis  in  the 
rivers  Tranquinhaem  and  Capybaribe.  There 
were  also  sorte  very  large  Ancylus.  Gelechia 
gossypyella  was  common  on  the  cotton  plan¬ 
tations.  We  also  collected  specimens  of  Pseud- 
olfersia  on  turkeys.  The  local  flora  is  inter¬ 
esting.  I  found  Cochlospermum  insigne  ST. 
H1L  ( Bixaceae ). 
11  IX.  We  returned  to  Recife,  where  we 
attended  to  the  most  pressing  business. 
12  IX.  In  the  Hospital  do  ¡solamento  we 
saw  a  patient  with  yellow  fever  who  had 
come  from  Natal  and  slept  in  Independencia. 
We  made  maeroscopical  examinations  in 
cases  of  ankylostomiasis  from  Campo  Gran¬ 
de  and  places  on  the  river  Capybaribe.  We 
also  observed  that  PI.  centimetralis  and  its  light 
variety  offered  great  attraction  to  the  miraci¬ 
dia  of  Schistosomum  mansoni. 
13  IX.  I  went  to  Jabotão  taking 
with  me  a  boy,  infected  with  Sch.  mansoni ,  to 
show  a  pond  where  he  used  to  bathe  ; 
there  we  found  many  PI.  centimetralis ,  but 
failed  to  find  any  cercaria  with  forked  tail. 
We  made  various  studies  at  the  laboratory. 
14  IX.  Excursion  to  the  river  Beberibe 
wheie  we  failed  to  find  any  Planorbis,  though 
we  found  eggs  of  Schistosomum  in  excrements, 
left  close  to  the  water. 
15  IX.  In  the  laboratory  we  infected 
some  Planorbis  with  the  mu  acidia  of  Sch. 
mansoni ;  afterwards  we  took  the  train  to 
Victoria  and  found  many  PI.  centimetralis  and 
some  cultratus  in  a  brook  which  passes 
through  the  town  ;  on  its  banks  we  found 
excrements  containing  eggs  with  a  lateral 
spine. 
16  IX.  We  took  the  train  early  in  the 
morning  and  passed  by  Gravatá,  where  we 
noticed  conditions  favotirab’e  to  the  forma¬ 
tion  of  a  focus  of  infection.  We  passed  the 
night  in  Bezerro,  and  found  many  centimetra¬ 
lis  in  the  Rio  Ipojuca. 
17  IX.  We  went  to  Gonçalves  Ferreira 
by  a  freight  train  and  visited  some  places, 
where  a  patient  had  been  infected.  In  the 
river  there  were  many  centimetralis.  After- 
tei wards  we  continued  the  railway  journey 
to  Caruaru,  where  we  enjoyed  a  fine 
view  from  the  Morro  da  Igreja. 
18  IX.  In  the  morning  we  collected 
many  centimetralis  in  the  Rio  Ipojuca,  which 
passes  through  the  town.  In  the  afternoon 
we  made  about  40  kilometers  on  horseback 
to  the  Fazenda  Fortaleza  near  Altino  ; 
we  were  informed  of  the  existence  of 
Triatoma  megista  in  the  neighbourhood. 
Dr.  CAMARA  and  his  family  received  us 
ver)'  well  and  gave  us  valuable  informa¬ 
tion.
