Albert  Gascard.    Paris.    Societe  d' editions  scientifiques.  1893. 
Contributions  to  the  study  of  shellac  of  India  and  Madagascar. 
This  thesis,  from  the  Paris  school,  shows  the  observations  of  the  author  on 
shellac  from  India.  The  other,  from  Madagascar,  is  a  new  article.  The  resin 
obtained  therefrom  yields  by  oxidation  with  permanganate  of  potash  in  alkaline 
solution  butyric  acid  and  ammonia.  In  the  wax  the  author  shows  the  existence 
of  eery  lie  alcohol,  etherized  with  formip  acid  or  oleic  acid,  and  acids  containing 
nitrogen  which  are  found  partially  in  the  free  state.  The  thesis  is  illustrated  by 
one  plate  of  the  shellac  from  Madagascar.
