salts,  673  water  (von  Uslar  and  Polstorff).  The  inorganic  salts  contain  in  100 
parts:  3170  phosphoric  acid,  29*78  potash  (Freitag). — Ibid.,  1876,  p.  12. 
Restoration  of  Faded  Writing. — Moisten  the  paper  a  little  with  water,  and  brush 
over  it  a  solution  of  sulphydric  ammonia.  Since  most  inks  contain  iron,  it  is  easy 
to  understand  that  there  will  be  formed  sulphide  of  iron,  which  is  black. — Ibid., 
p.  22,  from  Industrie-El. 
Arsenical  Poisoning. — Scolosuboff  has  found  that,  both  in  slow  and  rapid  poison- 
ing, the  arsenic  accumulates  chiefly  in  the  brain,  spinal  marrow  and  the  nerves.  On 
the  contrary,  comparatively  little  will  be  found  in  the  liver  and  muscles  generally. 
A  dog  had,  in  thirty-four  days,  taken,  in  increasing  doses,  from  5  mgrms.  to 
15  cgrms.  arsenious  acid.    On  examination,  was  found: 
In  100  grams,  muscles,  0*00015  grams. 
"  liver,  0*00271  " 
"  brain,  0*00885  " 
"  spinal  marrow,  0  00932  " 
or  1  :  io*8  :  36*5  :  37*3. — Ibid.,  p.  24,  from  Pharm.  Centralh.,  1875,  No.  45. 
Dita  Bark. — ("Am.  Jour.  Phar.,"  1873  (x1v)j  P-  3*6)  Jobst  and  Hesse  have  exam- 
ined this  bark  (from  Echites  scholaris,  L.  5  Alstonia  scholaris,  Brown),  and  reported 
their  results  at  some  length  in  "Ann.  d.  Ch.  und  Ph.,"  vol.  178.  After  a  descrip- 
tion of  it,  they  mention  ditain  obtained  by  Gruppe  in  Manilla,  and  then  detail  their 
chemical  investigation.  The  following  new  alkaloids,  acids,  etc.,  are  found  by  them  : 
Ditamin,  echicautchin,  echicerin,  echicerinic  acid,  echitein,  echiretin.- — Ibid.,  p.  27, 
from  Pharm.  Centralh.,  1875,  No.  49. 
Action  of  Borax  as  an  Antiseptic. — Dumas  and  Schnezler  state  that  they  have  found 
that  borax  coagulates  the  protoplasm  of  the  cells,  and  in  this  way  kills  lower  organ- 
isms; it  becomes,  then,  easy  to  understand  how  it  can  act  as  an  antiseptic. — Ibid., 
p.  30,  fr ora  Ann.  d.  Ch.  et  d.  Phys.,  1875,  P«  543* 
Pharmacy  in  Denmark. — The  Royal  Board  of  Health,  in  reply  to  numerous  peti- 
tions about  permission  to  start  new  pharmacies,  expresses  its  conviction  that  the 
public  will  undoubtedly  be  benefitted  by  competition  even  of  drug  stores,  under  cer- 
tain restrictions,  and  with  due  regard  to  existing  regulations  about  surveillance,  etc. 
It  has  been  resolved  to  revise  the  existing  poison-law,  particularly  with  respect  to 
the  manifold  uses  active  poisons  of  late  years  have  been  put  to,  both  in  manufactures 
and  in  the  household. — Ibid.,  p.  39,  etc.
