the  suet ;  in  other  respects  the  treatment  is  the  same  as  for  lard.  These 
greases  used  by  perfumers  have  a  general  title  of  »  body,"  tantamount  to 
the  French  nomenclature  of  corps ;  thus  we  have  pomades  of  hard  corps 
(suet),  pomades  of  soft  corps  (lard).  For  making  extraits,  such  as  extrait 
de  violette,  jasmin,  the  pomades  of  hard  corps  are  to  be  preferred,  but  when 
scented  pomade  is  to  be  used  in  fabrication  of  unguents  for  the  hair,  pomades 
of  soft  corps  are  the  most  useful. 
The  method  of  perfuming  grease  by  the  direct  process  with  flowers  having 
already  been  described  under  the  respective  names  of  the  flowers  that  impart 
the  odor  thereto,  it  remains  now  only  to  describe  those  compounds  that  are 
made  from  them,  together  with  such  incidental  matter  connected  with  this 
branch  of  perfumery  not  previously  mentioned. 
Acacia  Pomade,  commonly  called  Cassie  Pomatum,  is  made  with  a  purified 
body  grease,  by  maceration  with  the  little  round  yellow  buds  of  the  Acacia 
Farnesiana. 
Black  currant  leaves,  and  which  the  French  term  casse,  have  an  odor 
very  much  resembling  cassie  (acacia),  are  used  extensively  for  adulterating 
the  true  acacia  pomades  and  oils.  The  near  similarity  of  name,  their 
analogous  odor  (although  the  plants  have  no  botanical  connexion),  together 
with  the  word  cassia,  a  familiar  perfume  in  England,  has  produced  gene- 
rally confused  ideas  in  this  country  as  to  the  true  origin  of  the  odor  now 
under  discussion.  Cassie,  casse,  cassia,  it  will  be  understood  now  are  thm; 
distinct  substances  ;  and  in  order  to  render  the  matter  more  perspicuous  in 
future,  the  material  will  always  be  denominated  Acacia,  if  prepared  from 
the  Acacia  Farnesiana;  Casse,  when  from  black  currant;  and  Cassia  if 
derived  from  the  bark  of  the  Cinnamomum  cassia. 
BENZOIN  FOMADE    AND  OIL. 
Benzoic  acid  is  perfectly  soluble  in  hot  grease.  Half  an  ounce  of  benzoic 
acid  being  dissolved  in  half  a  pint  of  hot  olive  or  almond  oil,  deposits  on 
cooling  beautiful  acicular  crystals,  similar  to  the  crystals  that  effloresce 
from  vanilla  beans  ;  a  portion  of  the  acid,  however,  remains  dissolved  in 
the  oil  at  the  ordinary  temperature,  and  imparts  to  it  the  peculiar  aroma  of 
benzoin  ;  upon  this  idea  is  based  the  principle  of  perfuming  grease  with 
gum  benzoin  by  the  direct  process,  that  is,  by  macerating  powdered  gum 
benzoin  in  melted  suet  or  lard  for  a  few  hours,  at  a  temperature  of  about 
80°  C.  to  90°  C.  Nearly  all  the  gum  resins  give  up  their  odoriferous  prin- 
ciple to  fatty  "bodies,  when  treated  in  the  same  way  ;  this  fact  becoming 
generally  known  will  probably  give  rise  to  the  preparation  of  some  new 
remedial  ointments,  such  as  Unguentum  myrrhce,  Unguentum  assaf cetida: , 
and  the  like. 
Tonquin  fomade,  and  Tonquin  oil,  are  prepared  by  macerating  the 
ground  Tonquin  beans  in  either  melted  fat  or  warm  oil,  from  twelve  to 
twenty-eight  hours,  in  the  proportion  of 
Tonquin  beans  \  lb. 
Fatj  or  oil  4  lbs.
