Phenyl  Urethane,  a  non-toxic  antipyretic.  (This  should  not  be  confounded 
with  Europhen  or  Iso-Butyl-Ortho-Cresol  Iodide,  an  iodoform  substitute  con- 
taining nearly  one-fourth  combined  iodine).  The  Dispensatory  errs,  most 
decidedly,  in  calling  Phenyl  Urethane — Europhin  (p.  1674)  ;  and  the  greatest 
care  should  be  exercised  by  the  pharmacist  to  neutralize  this  blunder,  as 
Europhen — with  which  Euphorin  is  likely  to  be  confounded — brought  in 
contact  with  water,  splits  up  into  iodine,  and  a  new  and  soluble  iodine  com- 
pound. The  dangers  of  administering  free  iodine  in  the  form  of  1  to  2  gram 
doses  of  Europhen,  when  Euphorin  is  wanted  are  too  obvious  to  need  mention. 
"Aristol  "  is  referred  to  as  Dithymol-diiodide  or  Annidalin,  and  a  process  for 
making  is  given  (p.  879).  "Antiseptol  "  or  Cinchonine  lodosulphate,  Iodol 
or  Tetraiodopyrrol — one  of  the  oldest  of  iodoform  substitutes — Soziodol,  Sozal, 
Sulphaminol  and  Thiophene  are  described.  "  Dermatol  "  is  given  a  synonym 
of  Bismuth  Subgallate,  and  a  process  of  manufacture  is  detailed  (p.  345). 
"  Diuretin  "  is  defined  as  Sodio-Theobromine  Salicylate,  and  has  a  process  of 
making  given  (p.  1481).  "  Diaptherin  "  {not  Diphtherin),  or  Oxyquinaseptol  is 
mentioned,  and  the  method  of  obtaining  it  given  (p.  451). 
The  following  are  also  reviewed  :  Alumnol,  Naphtol,  Benzonaphtol,  Betol 
or  Salinaphtol,  Hydronaphtol,  Thiol — the  German  artificial  Ichthyol — Tumenol, 
allied  to  Ichthyol,  Lysol,  Creolin,  Naphtalin  and  derivatives,  Piperazine — the 
uric  acid  solvent — Resorcin,  Terebene,  Terpin  Hydrat,  Camphoric  Acid,  Paral- 
dehyde, Metaldehyde,  Sulphonal  and  allied  hypnotics — Trional  and  Tetronal, 
Guaiacol  and  Guaiacol  Carbonate,  Benzoate  and  Salicylate,  Chloralamide, 
Cocaine  Phenylate,  etc. 
Under  Ethylene  Bromide  (p.  141)  the  too-common  error  is  repeated  of 
describing  it  as  "a  faintly  brown-colored  liquid."  The  pure  compound  is  a 
colorless  liquid,  readily  decomposable  into  iodine  and  other  products.  Its  boil- 
ing point  is  stated  to  be  1310  C.    Wohler  gives  it  as  1290  C. 
One  of  the  most  valuable  features  of  The  National  Dispensatory,  in  the  past, 
has  been  its  up-to-date  references  concerning  plant  constituents.  This  reputa- 
tion seems  to  have  been  well  maintained  in  the  present  issue,  save  in  some  few 
cases. 
Under  the  composition  of  volatile  oil  of  juniper  (p.  1127)  the  indefinite  state- 
ment is  made  that  it  is  a  mixture  of  (C10'H16) — hydrocarbons  differing  in  boil- 
ing points.  Fliickiger  (1888)  has  shown  that  it  is  composed  essentially  of  two 
hydrocarbons,  the  more  abundant  of  which  when  heated  to  2700  is  changed  to 
a  hydrocarbon  (C10H16)  corresponding  to  cinene  of  oil  of  wormseed. 
Under  oil  of  hedeoma,  the  statement  only  is  made  that  it  "  contains  oxygen, 
but  its  exact  composition  has  not  been  ascertained,"  despite  the  excellent 
work  of  E.  Kremers  (A.  J.  P.,  1887,  p.  535),  and  F.  W.  Franz  (A.  J.  P.,  1888, 
p.  161),  who  found  hedeomol,  and  formic  and  acetic  acids.  Franz  also  found 
certain  oxygenated  liquids.    Kremers  believes  that  isoheptoic  acid  is  present. 
Further,  whilst  reference  is  made  under  the  constituents  of  Caulophyllum 
to  the  experiments  of  Lloyd,  anentthe  alkaloid  caulophylline — reported  by  him 
to  the  American  Pharmaceutical  Association  last  August — no  mention  is  made 
of  leontin,  a  compound  related  to  saponin,  previously  isolated  by  Lloyd, 
and  mentioned  in  the  discussion  following  his  paper  on  Caulophylline.  (See 
Proceedings,  A.  P.  A.,  1893,  p.  117.) 
In  the  description  of  the  properties  of  morphine  acetate,  the  statement  is
