a  certain  limit,  paralyzed  by  alcohol ;  beyond  this  limit,  strychnine 
becomes  poisonous  to  the  inebriated  animal.  Strychnine  is  an  excel- 
lent medicament  in  all  forms  of  alcoholism.  It  is  also  a  powerful  pro- 
phylactic.

Linimentum  terebinthince,  Br.P. — The  addition  of  more  than  the 
pharmacopoeial  quantity  of  water  with  the  view  of  avoiding  separation 
in  the  liniment  (see  Am.  Jour.  Ph.,  1886,  p.  428)  is  likely  to  inter- 
fere, more  or  less,  with  the  absorbent  action  of  the  turpentine  ;  but, 
according  to  G.  E.  Perry  (Phar.  Jour.  Trans.,  April  30,  1887,  p.  899), 
a  therapeutically  and  pharmaceutical^  satisfactory  liniment  is  obtained 
by  using  more  soap  and  less  water,  and  manipulating  as  follows  :  Dis- 
solve in  a  bottle  camphor  1  oz.  in  oil  of  turpentine  1 6  fluidounces, 
add  soft  soap  4  ozs.  and  water  1  oz.,  and  shake.  Thus  made  it  is  an 
elegant  creamy  emulsion,  remaining  sufficiently  liquid,  and  though  a 
slight  separation  will  take  place  after  a  time,  it  is  practically  perma- 
nent. 
Permanent  solution  of  mercuric  chloride. — Dr.  A.  C.  Bernays  states 
(Weekly  Med.  Rev.,  May  14,  1887,  p.  558)  on  the  authority  of  Dr. 
Stuetz  of  Jena,  that  by  adding  7  J  grains  of  citric  acid  to  each  quart  of 
water  used  in  making  solution  of  bichloride  of  mercury  there  would 
be  no  reduction  of  the  Hg  Cl2,  and  also  no  precipitate  when  albumi- 
noid solutions  are  admixed. 
Blaud's  pills. — The  paper  of  Mr.  W.  Duncan  (See  May  number,  p. 
235)  has  called  forth  two  communications  which  were  read  April  13, 
at  Edinburgh,  before  the  Pharmaceutical  Society  of  Great  Britain 
(Phar.  Jour.  Trans.,  April  23,  pp.  864-866).  Peter  Boa  gives  the 
following  formula  :  Rub  granulated  (precipitated)  ferrous  sulphate, 
30  grains,  with  sugar  10  grains,  add  potassium  carbonate  (15  to  16  p. 
c.  H20),  20  gr.,  triturate,  add  powdered  tragacanth,  3  gr.,  and  beat  into 
a  mass  for  twelve  pills.  The  beating  required  is  considerable, 
but  nothing  else  is  needed  to  make  a  mass  which  rolls  easily 
if  not  allowed  to  lie.  These  pills  keep  for  any  reasonable  time  with 
only  a  trifling  loss  of  ferrous  salt ;  it  is  unnecessary  to  coat  them. 
Thos.  Thompson  suggests  the  use  of  gelatin  capsules,  the  two  exsic- 
cated salts  to  be  incorporated  separately,  with  almond  oil,  then  mixed  and
