Am6c^obe^rPl89a61:m•}     Kino  in  Species  from  Myristica:  55 1 
tartaric  salts  in  fruits  and  other  parts  of  plants  leads  one  to  think 
that  a  frequent  secretion  of  crystallized  calcium  tartrate  would  not 
seem  improbable. 
The  results  of  the  foregoing  investigation  may  be  summed  up  as 
follows  : 
(1)  The  dried  juices  of  the  bark  of  several  Asiatic  species  of 
Myristica — for  instance,  of  M.  malabarica,  Lam.,  and  M.  fragrans, 
Houtt2 — as  regards  their  appearance  and  physical  qualities,  show 
but  little  difference  from  the  official  Malabar  kino. 
(2)  These  substances,  which  may  be  termed  "  Myristica  kinos," 
agree,  in  the  chemical  reactions  due  to  their  constituents,  in  all  im- 
portant points,  with  the  kino  of  Pterocarpus  marsupium.  It  can, 
therefore,  be  stated  that  drugs  of  a  very  similar  character,  and 
partly  close  resemblance  to  official  kino,  are  to  be  found  in  the 
families  of  Leguminosse  (Butea*  Pterocarpus,  Milletia),  Saxifragaceae 
(Ceratopetalum),  Myrtacese  (Eucalyptus,  Angophora)  and  Myristi- 
caceas. 
(3)  The  Myristica  kino  differs,  as  far  as  can  be  observed,  from  the 
Pterocarpus  kino,  and  probably  also  from  Butea  and  Eucalyptus 
kino,  by  containing,  in  the  crude  state  of  the  inspissated  fresh  juice, 
smaller  or  larger  amounts  of  a  distinctly  crystalline  calcium  salt, 
viz.:  calcium  tartrate,  suspended  in,  and  depositing  from,  the  liquid 
juice.  By  this  characteristic  admixture  it  can  be  easily  distinguished 
from  the  official  kino,  and  probably  also  from  other  kinos  of  com- 
merce. 
Whether  this  new  substance  might  ever  be  obtained  in  combina- 
tion with  the  production  of  nutmegs  and  mace,  so  as  to  play  the 
part  of  a  commercial  drug,  will  depend,  above  all,  upon  a  still  bet- 
ter knowledge  of  its  qualities,  its  formation  in  the  living  plant,  its 
quantitative  relations  and  similar  questions.  Perhaps  it  may  be  pos- 
sible, at  another  date,  to  give  some  more  particulars,  as  I  hope  to 
do,  in  connection  with  Dr.  van  Romburgh,  who  has  been  first  to 
observe  the  peculiar  micro-crystalline  character  of  this  Myristica 
kino. 
2  In  Watts'  "  Diet,  of  the  Econ.  Prod,  of  India,"  Vol.  V,  p.  314,  it  is  stated 
that  Myristica  longifolia,  Wall.,  an  evergreen  tree  of  Sikkim,  Khasia  Hills} 
Assam,  Pegu,  and  Tennasserim,  according  to  the  botanist  Kurz,  "exudes  a  red 
resin."  The  writer  would  be  obliged  for  any  sample  of  this  substance,  in  order 
to  compare  it  with  the  other  Myristica  kinos  mentioned  in  this  paper.
