deprived  of  its  odor  and  the  organisms  killed  in  a  very  short  time  ;  3), 
that  in  2  per  cent,  solution  the  alcoholic  fermentation  and  likewise  the 
formation  of  mould  is  prevented. — Idem.^  p.  445. 
On  Carbohydrates, — Franchimont  has  made  studies  upon  several  of 
the  sugar  varieties,  which  may  be  summarized  as  follows: 
I.  On  Tunicin  or  Animal  Cellulose.  The  mass,  purified  by  treatment 
with  acids,  alkalies,  alcohol  and  ether,  was  dissolved  in  ammoniacal 
solution  of  cupric  oxide  and  precipitated  by  hydrochloric  acid,  washed 
and  dried.  It  was  then  treated  with  sulphuric  acid  in  the  cold  and 
examined  in  the  polariscope,  when  it  showed  right  rotation.  After 
boiling  for  48  hours  with  inverted  condenser,  the  excess  of  acid  was 
removed  with  barium  carbonate,  and  the  solution  concentrated  to  the 
point  of  crystallization.  The  substance  so  gotten  had  aH  the  appear- 
ance of  ordinary  glucose,  and  showed  similar  rotatory  power,  diminish- 
ing after  some  hours  nearly  one-half.  He  considers  the  sugar  formed 
as  ordinary  glucose,  and  therefore  the  tunicin  may  have  the  same  for- 
mula as  vegetable  cellulose,  although  the  possibility  remains  that  it 
may  be  a  multiple  of  it. 
II.  On  Glucose.  Upon  attempting  to  get  an  acetyl  compound  from 
glucose  by  Liebermann's  method,  using  acetic  anhydride  and  fused 
sodium  acetate,  he  obtained  a  compound,  crystallizing  out  of  ether  in 
dazzling  white  cauliflower-like  crystals,  which  appeared  to  be  an 
octacetyl-saccharose  formed  from  two  molecules  of  glucose.  This 
compound  is  not  readily  oxidizable,  and  the  aldehyde  character  of 
glucose  seems  to  have  vanished  entirely.  The  author  proposes  at  a 
future  date  to  make  public  some  views  on  the  structure  of  glucose 
which  will  explain  this  fact  as  observed. 
III.  On  Vegetable  Cellulose.  Upon  trying  the  Liebermann  method 
upon  ordinary  Swedish  filter  paper  no  acetyl  compound  of  cellulose 
was  gotten  until  a  few  drops  of  sulphuric  acid  were  added,  when  a 
strong  reaction  set  in.  Several  products  were  gotten,  the  best  crystal- 
lized of  which  seems  to  be  a  tri-glucose,  containing  eleven  acetyl  groupes, 
a  compound  which  might  result  from  three  molecules  of  glucose  by  the 
loss  of  two  molecules  of  water.  The  author  has  studied  also  the 
acetyl  derivatives  of  other  carbohydrates,  such  as  inulin,  saccharose, 
starch  and  dextrin,  and  promises  to  communicate  these  results  at  a 
future  time. — Ber.  der  Chem.  Ges.^  xii,  p.  1938.
