Carobin  crystallizes  in  feltlike  silky  needles^  is  inodorous^  has  a  faint 
alkaline  and  bitterish  taste,  infusible,  insoluble  in  ether,  readily  soluble 
in  boiling  water  and  boiling  alcohol  and  is  precipitated  by  tartar  emetic 
and  ammonium  carbonate,  the  latter  precipitate  being  soluble  in  an  excess 
of  the  reagent.  Tannin  and  metallic  chlorides  and  iodides  cause  no 
precipitate.  It  is  not  a  glucoside,  does  not  show  any  striking  color 
reactions  and  yields  with  acetic  acid  a  compound  crystallizing  in  fine 
needles. 
Carobic  acid  forms  stellate  fusible  needles  of  an  aromatic  odor  and 
acid  taste,  is  soluble  in  water  and  dilute  alcohol  and  is  precipitated 
by  the  acetates  of  lead  and  copper. 
Steocarobic  acid  is  pale-brown,  of  a  tonka-like  odor,  of  an  acid  and 
balsamic  taste,  and  soluble  in  cold  absolute  alcohol  and  ether. 
Carobone  is  greenish,  amorphous,  aromatic,  soluble  in  alcohol,  sp. 
gr.  "815,  in  caustic  alkalies  and  in  boiling  solution  of  sodiuni  car- 
bonate. 
Caroba  balsam  is  dark-brown,  syrupy,  agreeably  aromatic,  resem- 
bling tonka  and  by  heat  may  be  evaporated  to  a  nearly  inodorous  resin. 
Caroba  leaves  have  lanceolate,  often  sub-obovate  leaflets  and  are  used 
in  Brazil  in  place  of  sarsaparilla,  in  cutaneous  affections  and  as 
an  antisyphilitic,  usually  in  the  form  of  infusion,  120  grams  to 
1  liter,  in  doses  of  a  teaspoonful  three  times  daily.  An  elec- 
tuary known  as  massa  de  Dr.  Alves  Carneiro "  is  composed  of  the 
powders  of  caroba  leaves  90  grams,  sarsaparilla  and  senna  each  30 
grams,  (calomel  2  grams  and  simple  syrup  q.  s.,  and  is  given  in  cuta-
