If  fats  are  heated  until  they  become  thin  liquid,  and  before 
they  have  become  entirely  clear,  they  will  congeal  near  the 
fusing  point  without  elevation  of  temperature.  Ibid.  N.  18,

Peruvian  gum  is  used  in  Germany  for  thickening  and  fixing 
colors  upon  cotton  goods  and  wall  papers.  It  consists  of  the 
powder  of  the  "  peruvian  root,"  collected  in  Peru  from  an 
unknown  plant ;  the  roots  are  1  to  2  inches  long,  of  the  thick- 
ness of  a  quill  and  over,  very  hard,  reddish  brown  externally, 
internally  yellowish  white  with  a  yellow  centre,  inodorous  and  of 
an  insipid,  afterwards  bitterish,  taste ;  alcohol  dissolves  some 
yellow  coloring  matter.  The  powder  swells  with  15  to  17  parts 
of  cold  water  to  a  stiff  paste  of  the  consistence  of  honey,  which 
is  free  from  starch  and  sugar ;  mixed  with  much  water,  a  sedi- 
ment occurs  amounting  to  8  or  10  per  cent,  and  entirely  insolu- 
ble in  boiling  water.  Its  solubility  in  dilute  acids  and  caustic 
potassa  and  its  swelling  with  water  prove  the  Peruvian  gum  to 
consist  mostly  of  bassorin.  Its  thickening  property  is  six  times 
greater  than  Senegal  gum,  which,  according  to  Liebe,  possesses, 
however,  greater  adhesiveness.  Ibid.  N.  20,  460,  461,  from 
Deutsche  Industrie  Zeitz.
