were  results  in  4  cases.  The  bearers  of 
these  eggs  had  apparently  been  infected  in  the 
Capital  and  in  Lagoa  Grande;  one  of  them 
had  come  from  Pau  d’Alho  in  Pernambuco. 
Pernambuco. 
Shortly  after  arriving,  we  examined  spe¬ 
cimens  from  25  marine  apprentices;  7  of 
them  were  infected  by  the  trematode  under 
study.  We  received  specimens  for  exami¬ 
nation  from  the  hospital,  the  lunatic  asylum 
and  the  alms-house.  15  out  of  46  individuals 
contained  eggs  of  Schistosomum.  We 
also  made  22  examinations  of  specimens, 
gathered  at  random  during  our  journey  in 
the  interior  of  the  State  ;  8  of  them  gave 
positive  results.  The  bearers  of  these  eggs 
came  from  the  following  places  in  the  in  e- 
rior  of  Pernambuco  :  Bom  Jardim,  Bebo 
Jardim,  Limoeiro,  Campo  Grande,  Pau  d'Alho, 
Victoria,  Bezerros,  Beberibe,  Gonçalves  Fer¬ 
reira,  Caruaru,  A 'tino,  Palmares,  and  Ja- 
boatão.  These  places  are  situated  on  ti  e 
banks  of  the  follow  mg  rivers:  Capibaribe, 
ipojuca,  Beberibe,  Una  and  their  afflueirs. 
In  all  these,  the  Rio  Beberibe  excepted,  P  a- 
norbis  centimetralis  LUTZ  was  found. 
Sergipe. 
As  usual,  we  first  examined  specimens 
from  pupils  of  the  Marine  School  ;  6  out  <  f 
25  were  proved  to  be  bearers  of  Schistosomum 
eggs.  We  examined  specimens  from  18 
prisoners  with  5  positive  results,  and  from 
24  patients  of  the  Hospital;  8  of  these  had 
Schistosomum.  Out  of  8  examinations  of  spe¬ 
cimens,  gathered  at  random,  5  showed  the 
eggs.  The  places  where  the  bearer  of  the  adult 
form  of  this  worm  had  stayed  for  some 
time,  were:  Aracaju,  Japaratuba,  Maroim, 
São  Christovão,  Laranjeiras,  Itaporanga,  Ca- 
pella  and  Propria.  In  several  of  these 
places  we  personally  verified  the  presence  of 
Planorbis  oliváceas ;  some  of  them  had  been 
infected  by  the  miracidium  of  Schistosomum 
mansoni,  as  was  proved  by  their  producing 
cercariae  of  this  trematode.  In  Propriá  we 
found  morever  Planorbis  centimetralis  LUTZ. 
Bahia 
Out  of  25  oohelminthologicat  examinations 
of  specimens,  sent  from  the  School  of  Mari¬ 
ne  Apparentices,  4  were  positive  as  regards 
Schistosomum.  From  the  Hospital  we  obtain¬ 
ed  8  different  specimens,  of  wnich  3  con¬ 
tained  eggs  with  a  lateral  spine.  In  9  speci¬ 
mens,  gathered  near  rivers  and  ponds  con¬ 
taining  infected  Planorbis ,  we  obtained  5 
positive  results.  The  places  in  Bahia,  where 
the  bearers  of  these  Schistosomum  eggs  had 
always  lived  or  had  stayed  for  some 
time,  were:  Feira  de  Santa  Anna  (here 
we  found  Planorbis  oliváceas  in  the 
Tanque  da  Nação),  Cachoeira  with  the  rivers 
Pitanga  and  Caquende  (here  we  verified  the 
presence  of  Planorbis  infected  by  this  tre¬ 
matode),  Itapagipe  and  Silva  Jardim. 
On  our  first  journev  to  Pernambuco,  we 
went  on  shore  at  Maceió  and  visited  the  Hos¬ 
pital.  In  answer  to  our  inquiry,  as  to  whether 
there  were  patients  suffering  from  amoebic 
d  sentery  we  were  told  that  there  was  an 
old  and  exceptionally  severe  case,  which  had 
defied  all  treatment.  We  asked  them  to 
send  us  a  specimen  from  the  patient,  if 
possible,  so  that  we  might  examine  it  on 
board.  On  our  returning  to  the  ship  we 
found  the  specimen  which  was  immediately 
examined  ;  we  failed  to  find  any  amoeba,  but 
discovered  plenty  of  Schistosomum  eggs  ; 
•t  even  showed  a  greater  proportion  of  eggs 
than  any  specimen  examined  up  to  that  date. 
We  wrote  several  times  asking  for  informa¬ 
tion  about  this  patient,  but  unfortunately 
failed  to  get  any. 
Of  312  specimens  examined,  71  contained 
eggs  of  Schistosomum,  giving  an  average  of 
22,  75  °/o.  Resuming  these  rapid  and  insuf¬ 
ficient  statistics  of  human  bearers  of  the 
parasite  found  in  the  northern  States  visited 
on  our  journey,  we  have:
