Vapor  density : 
I.  0-1168  gm.  subst.  replaced  21  cc.  air  =  4*76. 
II.  0-1050  "     "  "       18-7  cc.  air  =  4'67. 
Calculated  for  C10H16  =  4*71. 
Fraction  D.  167-169°,  b.  p.  168°  C. — In  somewhat  larger  quan- 
tity than  Fraction  B,  of  fragrant  odor,  colorless,  sp.  gr.  0*8678  at 
16°  C,  and  dextro-rotary=  +  56'9°. 
Combustions  as  follows  gave  results  for  a  hydrocarbon : 
I.  0*1185  gm  yielded  0-381  gm.  C02  and  0-124  gm.  H20.

II.  0-172  gm.    "         "     31-3cc.  air=4-68. 
Calculated  for  C10H16=4-71. 
Fraction  E.  170-171°  C,  b.  p.  171°  C— Of  this  fraction  only  a 
small  quantity  could  be  separated,  but  it  consisted  of  a  distinct  frac- 
tion, with  constant  boiling  point  of  171°  C.  The  specific  gravity  was 
found  to  be  0*8737  at  16°  C,  colorless,  fragrant  odor  and  dextro- 
rotary=-f584°. 
Combustions  gave  results  as  follows  :
