548  Kino  in  Species  from  Myristica.  {A^ioberPis96rm' 
in  sending  the  drug  from  East  India  to  the  Kew  Museum.  Also 
the  amount  of  ash  (i-i  per  cent,  as  the  average  of  several  determi- 
nations) was  quite  analogous  to  the  amount  of  inorganic  residue 
found  in  the  better  qualities  of  commercial  genuine  Malabar  kino. 
Only  in  two  respects  was  a  negative  result  obtained  in  comparison 
with  Pterocarpus  kino,  and  also  with  certain  kinds  of  Eucalyptus 
kino  ;  that  is  to  say,  the  substance  in  question  neither  yielded  to 
ether  even  the  smallest  quantity  of  an  organic  compound  of  the 
quality  of  catechin  or  pyrocatechin  (cf.  "  Pharmacographia,"  1879,  p. 
196),  nor  was  it  possible  to  obtain  any  crystals  of  the  kinoi'n  of 
Etti,  by  exhausting  with  ether  the  kino  solution,  first  heated  for 
some  time  with  hydrochloric  acid. 
Under  these  circumstances  I  thought  it  advisable  to  apply  to  the 
Government's  botanical  garden,  of  Buitenzorg  (Java),  for  samples  of 
the  inspissated  secretions  of  the  barks  of  either  M.  malabarica  or 
other  species  of  Myristica,  and  to  compare  such  samples  with  the 
"  Kat  jadikai  "  received  from  Professor  Warburg,  and  afterwards, 
in  smaller  quantity,  directly  from  Kew,  by  the  kindness  of  the 
director  of  the  Royal  Gardens.  The  samples  which  were  sent  to 
me  a  few  weeks  ago,  and  for  which  I  am  highly  and  gratefully 
indebted  to  the  director,  Dr.  M.  Treub,  as  well  as  to  the  assistant 
director,  Dr.  P.  van  Romburgh,  consisted  of  small  portions  of  the 
still  liquid  juice  of  the  bark  of  (ci)  Myristica  glabra,  (b)  "  kapoeas," 
from  M.  species,  and  (c)  M.  succedanea,  as  well  as  of  a  few  grammes 
of  dried  kino-like  substance,  drawn  Irom  M.  fragrans,  which  I 
received  within  the  last  few  days. 
The  examination,  conducted  in  the  same  way  as  that  of  the 
special  sample,  "  Kat  jadikai,"  from  Kew,  showed  very  soon  that 
the  three  liquid  kinos  agreed  completely  in  all  the  five  reactions 
discussed  above,  with  the  concentrated  aqueous  solution  of  the  dried 
juice  of  M.  malabarica,  of  Kew,  exception  being  made  with  regard 
to  a  very  curious  turbidity  and  microcrystalline  sediment,  which 
was  removable  by  filtration.  The  three  filtered  juices,  by  careful 
evaporation  at  temperatures  of  500  to  jo°  C,  gave  dry  residues 
quite  similar  in  every  respect  to  the  first  examined  "  Kat  jadikai," 
while  the  same  liquids,  evaporated  without  previous  filtration, 
formed  a  much  paler  residue.  These  last-mentioned  kino-like  dry 
residues  presented  the  same  appearance  of  a  pale  reddish-brown 
extract  as  the  dried  bark  juice  of  the  official  Myristica  fragrans, 
kindly  forwarded  by  the  directors  of  the  Buitenzorg  Gardens.
