Iodopyrine  {iod-antipyrine)  and  iod-acetanilide. — These  two  iodine 
derivatives,  made  by  the  Chemische  Fabrik  in  Hoechst  a.  M.,  have 
been  examined  physiologically  by  E.  Munz,  who  finds  the  last  men- 
tioned entirely  inert,  possibly  on  account  of  its  insolubility.  The 
first  retains  the  action  of  antipyrine  and  possesses  additionally 
the  therapeutic  action  of  iodine  as  an  alkaline  iodide  ;  taken  inter- 
nally it  is  decomposed  in  the  stomach  into  iodine  and  antipyrine. 
Iodopyrine  forms  colorless,  lustrous,  prismatic  needles ;  melting  at 
1600  C.  It  is  tasteless  and  odorless  and  difficultly  soluble  in  water 
and  alcohol. — {Pragcr  Med.  Wochenschr.)  Oestcrr.  Ztschr.  f.  Pharm.y

Ly coper sicum  esculentum. — The  tomato  fruit  has  been  chemically 
examined  by  G.  Briosi  and  T.  Gigli.  On  an  average  the  fresh  fruit 
contains:  Seeds  10-9  per  cent.,  pulp  85-4  per  cent,  and  skin  3-7  per 
cent.  The  pulp  can  be  separated  into  a  yellow  juice  and  a  red 
residue,  which  is  tasteless  after  washing  ;  the  juice  0:1  an  average 
has  the  specific  gravity  1-0217  and  contains  levulose,  citric  acid 
(0-4  to  0-65  per  cent,  of  the  juice),  albuminoids  and  ash  which  is 
composed  of  60  per  cent,  potassium  salts.  Minute  traces  of  alka- 
loid are  indicated  ;  tartaric  acid  could  not  be  detected.  The  red 
residue  will  impart  its  coloring  matter  to  ether,  alcohol,  chloroform 
and  aqueous  alkalies.  The  alcoholic  solution  is  not  changed  by  ferric 
chloride,  dilute  acids  or  alkalies ;  on  addition  of  strong  nitric  acid  a  . 
transient  blue  color  is  produced  ;  the  residue  on  evaporating  the 
alcoholic  solution  becomes  blue  by  adding  sulphuric  acid  ;  the 
coloring  matter  resembles  that  of  saffron. —  Chemiker  Ztg.,  1891,

Solutions  of  Active  Medicaments. —  At  the  Feb.  4th  meeting 
of  the  Societe  de  Pharmacie  de  Paris,  M.  Petit  proposed  that  medica-  1 
ments  like  aconitine,  digitalin,  strophanthin,  etc.,  be  prepared  in  1 
to  IOOO  solutions.  Alcohol  being  necessary  to  the  conservation  of 
such  preparations,  and  being,  at  the  same  time,  lighter  than  water, 
M.  Petit  proposes  to  bring  the  liquid  to  the  proper  density  by  the 
addition  of  glycerin.  The  proportions  to  use  for  making  a  glycerized 
alcohol  having  the  same  density  as  water  are  given  as  follows; 
Glycerin  (D=i-250  at  1 50),  333  ccm.;  distilled  water,  147  ccm.:
