the  reach  of  probability  that  they  may  have  been  carried  here 
from  the  native  countries  of  this  species  in  the  Pacific  or  Indian 
Oceans. 
The  Jacca*  is  a  large  tree  attaining  a  height  of  30  to  50 
feet,  and  in  its  general  character  concurs  with  that  of  the  true 
bread-fruit  tree,  (Artocarpus  incisa,  L.) 
The  fruit  of  this  species,  as  well  as  of  A.  incisa,  is  the  com- 
pound inflorescence  of  the  pistillate  flowers  ripened  into  a  syn- 
carpium  or  compound  berry.  It  is  composed  of  numerous  car- 
pels, which  are  united  at  the  base  to  the  common  fleshy  recepta- 
cle forming  the  axis  of  the  syncarpium,  while  their  apices  are 
connected  and  form  the  rough  green  rind  or  outer  covering  of  the 
fruit;  the  rough  points  on  the  outside  of  the  fruit  of  A.  incisa 
being  pyramidal  or  conical,  while  they  are  pentagonal  or  hexa- 
gonal in  A.  integrifolia.  The  shape  of  the  latter  fruit  is  ovate-cor- 
date ;  it  is  from  12  to  30  inches  long,  by  from  6  to  12  in  diame- 
ter, and  weighs  from  10  to  90  pounds.  As  is  the  case  with  the 
bread-fruit  proper,  by  far  the  larger  number  of  ovaries  prove 
abortive,  and  their  perianths  are  gradually  converted  into  a  yel- 
lowish gelatinous  pulp,  which  is  the  principally  edible  portion, 
and  which  is  eaten  in  the  same  manner  as  the  pulp  of  the  other 
species,  though  its  odor  is  stated  to  be  repulsive.  The  sterile 
carpels  become  compressed  into  fleshy  ligulae,  which  surround 
the  fertile  ones.  The  latter,  the  fruits  proper,  are  the  nuts  be- 
fore us. 
The  pericarp  is  of  the  shape  of  a  dried  prune,  but  from  two  to 
four  times  its  size,  with  a  long  /  for  its  axis,  somewhat  triangu-
