Reactions  of  Certain  Alkaloids  with  Fluoniobate  op 
Potassium  and  Chlorine  in  Sulphuric  Acid. — The  fluoniobate 
reagent  is  prepared  by  dissolving  1  gm.  of  the  salt  in  40  ccm.  of  con- 
centrated sulphuric  acid,  and  then  heating  to  drive  off  the  hydrofluoric 
acid.  With  apomorphine,  this  solution  gives  a  very  intense  red,  slight- 
ly brownish,  which  becomes  of  an  ochre  yellow  color  on  adding  water. 
Morphine  acts  in  the  same  manner,  but  the  coloration  is  weaker.  The 
chlorine  reagent  is  easily  prepared  by  saturating  concentrated  sulphuric 
with  pure,  dry  chlorine.  With  this,  narcotine  gives  a  very  beautiful 
violet  coloration,  which  passes  rapidly  to  wine-red  and  yellow ;  heated 
slightly,  the  mixture  becomes  red.  Narceine  turns  of  an  olive  green 
color  which  turns  gradually  blue,  with  streaks  of  red.  Brucine  takes 
a  red  color,  as  with  nitric  acid. — A.  I.  Brociner,  in  J.  de  Ph.  et  de  Ch.;

Action  of  Hypobromite  of  Sodium  upon  Certain  Aromatic 
Derivatives  ;  and  Differential  Reaction  Between  Hippuric 
and  Benzoic  Acids. — If  hypobromite  of  sodium  containing  an  ex- 
cess of  alkali  be  boiled  with  hippuric  acid,  gaseous  bullae  are  disen- 
gaged and  the  liquid  clouds  with  a  reddish-yellow  tint.  The  precipi- 
tate, which  goes  down  on  cooling,  appears  as  a  powder  of  a  kermes-red 
color.  Benzoic  acid  under  like  conditions  gives  no  reaction.  Glyco- 
col  causes  a  decoloration  of  the  hypobromite,  with  a  disengagement  of 
azotic  gas.  Testing  the  action  of  hypobromite  of  sodium  upon  a  large 
number  of  azotized  products  of  the  aromatic  series,  the  following  re- 
sults were  obtained :  Benzamide  and  Benzonitril  gave  nothing  when 
cold ;  on  ebullition,  gave  a  kermes-red  precipitate.  Aniline ;  the 
aqueos  solution — even  when  largely  diluted — gave  an  orange  precipi- 
tate ;  the  reaction  was  nearly  as  sensitive  as  that  of  the  hypochlorite  of 
lime.  Methylaniline  ;  a  yellow  precipitate  slightly  greenish  when  cold, 
but  becoming  red  on  boiling.  Toluidine ;  same  results  as  for  ani- 
line; the  precipitate  is  browner.  Anilides ;  nothing  with  cold;  on 
boiling,  a  reddish  precipitate.  An  odor  of  cyanide  of  methyl  is  disen- 
gaged. Hydrochlorate  of  diamine-metaphenylene,  diamido-benzoic  acid, 
diamine-toluilene ;  all  gave — hot  or  cold — a  red  maroon  precipitate. 
Ferrocyanides,  ferricyanides,  nitro-prussiates ;  on  boiling,  all  gave  a 
red  precipitate  of  ferric  hydrate.  Pyridine;  no  reaction.  Quinoleine ; 
does  not  give  the  orange-red  precipitate  except — which  is  frequently 
the  case — aniline  is  present. — Acad,  des  Sci.y  cvii,  662.  1888  ;  J.  de
