COMMERCIAL  AND  TRADE  INTEREST. 
Celluloid  Substitute. — Considerable  interest  has  been  aroused 
in  the  non-combustible  substitute  for  celluloid  which  has  been  in- 
vented by  a  professor  in  a  Japanese  university,  and  for  the  manu- 
facture of  which  a  company  has  been  organized  in  Japan.  The  fac- 
tory buildings  are  now  in  course  of  construction  and  it  is  planned 
to  begin  in  April  of  this  year,  or  soon  after,  the  manufacture  of 
waterproof  cloth,  composition  tiles  and  insulators.  As  soon  as  the 
machinery,  which  has  been  ordered  in  the  United  States,  arrives, 
the  manufacture  of  imitation  leather,  linoleum,  stained  glass,  marble, 
lacquers  and  varnishes  will  be  started.  Patent  rights  have  been  ob- 
tained for  the  process  in  Japan  and  have  been  applied  for  in  Great 
Britain,  France  and  the  United  States.  Of  the  twenty-one  patents 
applied  for  in  this  country,  eleven  have  actually  been  granted  under 
date  of  November  6,  1917,  and  bear  serial  numbers  1,245,818  and 
1,245,975  to  1,245,984,  inclusive.  (From  the  Journal  of  Industrial 
and  Engineering  Chemistry ,  April  1,  1918.)

facture of  drugs  formerly  made  in  Germany  was  the  Rector  Chem- 
ical Company,  of  New  York,  which  holds  license  No.  5,  for  the  manu-
