been  able  to  devise  a  machine  which  will  furnish  his  brother 
pharmacists  with  a  means  of  aiding  his  pecuniary  advancement  as 
well  as  developing  his  professional  standing,  by  enabling  him  to 
improve  his  reputation  amongst  physicians  by  showing  his  ability 
to  make  his  own  preparations,  rather  than  confining  his  energies  to 
simply  selling  the  productions  of  others.

ABSTRACTS  FROM  THE  FRENCH  JOURNALS. 
Translated  for  the  American  Journal  of  Pharmacy. 
Iodoform ated  Guaiacol. — The  mixture  used  by  M.  Picot  in  his 
new  treatment  of  tuberculosis  by  hypodermic  injections  is  formu- 
lated as  follows  in  a  communication  (March  3),  to  the  Academie 
de  Medecine :  The  basis  of  the  liquid  is  sterilized  olive  oil  and 
vaselin ;  each  cubic  centimetre  of  this  excipient  should  contain  I 
cgm.  of  iodoform  and  5  cgm.  of  guaiacol.  The  same  mixture  is 
used  in  cases  of  pleurisy. 
Iodoformated  Guaiacol  with  Eucalyptol. — At  a  meeting  of 
the  Acadhnie  de  Medecine  (March  10),  M.  Pignol  gave  his  formula 
for  the  hypodermic  treatment  of  tuberculosis,  as  follows  :  Steri- 
lized oil  of  sweet  almonds,  of  which  each  ccm.  should  contain  14 
cgm.  of  eucalyptol ;  5  cgm.  of  guaiacol,  and  1  cgm.  of  iodoform. 
Preparation  of  Magnesium  Hydrate. — M.  Fleury  (R'epert.  de  Phar. 
April  10),  advises  pharmacists  to  prepare  their  own  hydrated 
magnesia,  and  to  make  it  as  follows :  Boil  the  sulphate  of  mag- 
nesium with  10  or  12  times  its  weight  of  water,  adding  gradually,  a 
15  or  20  per  cent,  solution  of  caustic  soda.  Ebullition  should  be 
continued  for  twenty  minutes  after  the  liquor  shall  have  acquired  a 
strong  alkaline  reaction,  and  then  it  should  be  allowed  to  stand  for 
two  hours.  The  liquid  is  now  decanted  and  the  precipitate  washed 
until  the  water  ceases  to  give  the  reaction  of  sulphuric  acid  with 
acidulated  chloride  of  barium.  The  hydrated  magnesia  is  then 
dried  at  a  moderate  temperature. 
Fluoride  of  Silver  :  Its  Preparation  and  Properties. — M. 
Moissan  stated  at  the  meeting  of  March  10,  of  the  Societe  de 
Pharmacie,  that  this  salt  is  not,  as  has  been  supposed,  difficult  of 
preparation.  It  is  only  necessary  to  effect  a  reaction  of  hydrofluoric 
acid  upon   carbonate    of  silver  which    is   pure   and    free  from
