additional  facts.  It  appears  that  the  forms  and  compositions  of 
all  these  bodies  are  much  like  those  of  our  own  planet,  but  peculiar 
conditions  are  occasionally  found.  One  remarkable  incident  was 
the  finding  of  an  element  in  the  sun  before  it  was  known  to  exist 
on  the  earth,  and  the  subsequent  discovery  .of  it  in  certain  parts  of  the 
United  States  in  amounts  sufficient  to  make  it  available  for  war 
purposes.  This  lecture  will  present,  vividly,  by  lantern  slides,  many 
interesting  facts  concerning  the  form  and  nature  of  the  heavenly 
bodies,  and  incidentally  discuss  the  possibility  of  the  existence  of  in- 
telligent beings  on  other  worlds.

The  industries  based  upon  the  chemical  utilization  of  cellulose, 
the  substance  which  constitutes  cotton  fiber  and  which  may  be  sep- 
arated also  from  wood  pulp,  are  of  increasing  importance.  Var- 
nishes, artificial  leather,  artificial  silk,  celluloid,  paper  of  all  de- 
scription and  kinds,  paper  clothes,  and  scores  of  other  products,  are 
manufactured  in  great  quantities.  The  lecture,  which  will  be  il-
