Tho  benzoin,  santal  wood,  and  tolu,  are  to  be  powdered  and  mixed  by  sift- 
ing thecn,  adding  the  ottos.  The  nitre  being  dissolved  in  the  mucilage,  is 
then  added.  After  well  beating  in  a  mortar,  the  pastils  are  formed  in  shape 
with  a  pastil  mould,  and  gradually  dried. 
The  Chinese  josticks  are  of  a  similar  composition,  but  contain  no  tolu. 
Josticks  are  burned  as  incense  in  the  temples  of  the  Buddahs  in  the  Celes- 
tial Empire,  and  to  such  an  extent  as  to  greatly  inhance  the  value  of  san- 
tal wood.

Prior  to  mixing,  dissolve  £  oz.  nitre  in  half  a  pint  of  distilled  or  ordinary 
rose  water ;  with  this  solution  thoroughly  wet  the  charcoal,  and  then  allow 
it  to  dry  in  a  warm  place. 
When  the  thus  nitrated  charcoal  is  quite  dry,  pour  over  it  the  mixed  ottos, 
and  stir  in  the  flowers  of  benzoin.  When  well  mixed  by  sifting  (the  sieve

mucilage  to  bind  the  whole  together,  and  the  less  that  is  used  the  better. 
A  great  variety  of  formula  have  been  published  for  the  manufacture  of 
pastils;  nine-tenths  of  them  contain  some  woods  or  bark,  or  aromatic  seeds. 
Now  when  such  substances  are  burned,  the  chemist  knows  that  if  the  lig* 
neous  fibre  contained  in  them  undergoes  combustion — the  slow  combustion 
— materials  are  produced  which  have  far  from  a  pleasant  odor ;  in  fact,  the 
smell  of  burning  wood  predominates  over  the  volatilized  aromatic  ingre- 
dients ;  it  is  for  this  reason  alone  that  charcoal  is  used  in  lieu  of  other  sub-
