found  it  to  consist  chiefly  of  erythroretin,  crysophanic  acid,  and  other  active 
constituents  of  that  drug.  It  may  he  inferred  from  what  is,  known,  that  tinc- 
tures keep  best  carefully  closed,  and  in  the  dark.  Our  space  will  not  ad- 
mit of  further  comment. 
The  Tax  Bill  for  Internal  Eevenue. — This  measure,  we  learn  on 
going  to  press,  has  become  a  law,  and  the  106th  section  bearing  on  apothe- 
caries appears  to  have  passed  very  much  as  printed  in  our  May  number  at 
page  282,  as  recommended  by  the  College  Committee,  except  the  last  clause 
in  parenthesis,  which  was  omitted.  We  have  been  unable,  by  diligent  in- 
quiry, to  get  information  on  many  points  of  interest  in  connection  with 
the  operation  of  the  law,  as  to  when  it  will  practically  go  into  effect,  how  it 
will  operate  on  stock  on  hand,  etc.,  but  we  presume  the  government  will 
take  the  proper  measures  to  publish  the  whole  law  in  a  clear  and  explicit 
form,  so  that  all  may  understand  their  relations  with  it. 
Ung.  Cadmii  Iodidi.— Mr.  Charles  Heinitsh,  of  Lancaster,  says,  that  the 
ointment  of  iodide  of  cadmium  is  getting  considerably  into  use  in  that  city 
as  a  substitute  for  the  officinal  Ung.  Potassii  Iodidi,  because  it  does  not 
discolor  the  skin.    He  recommends  the  following  formula : — 
R.  Cadmii  Iodidi    ......  ^j. 
Adepis  ^j. 
01.  Neroli  gtt.  x. 
iEtheris    .......        gtt.  xx. 
Rub  the  iodide  with  the  ether,  till  in  fine  powder,  then  add  the  lard  and 
oil,  and  thoroughly  mix  them, 
American  Medical  Association. — The  annual  meeting  of  this  body, 
postponed  last  year  on  account  of  the  rebellion,  is  farther  postponed  until 
June,  18G3,  by  order  of  the  Committee  of  Arrangements,  dated  Chicago, 
March  20th,  1862,  as  noticed  in  the  Chicago  Medical  Examiner. 
Erratum. — In  our  last  number,  page  241,  line  18  from  the  top,  the 
printer  made  us  use  the  word  "  Anatomy."  The  intelligent  reader  would 
at  once  from  the  context  discover  that  it  should  be  "  Antimony." 
First  Outlines  of  a  Dictionary  of  the  Solubilities  of  Chemical  Substances.  By 
Frank  H.  Storer. 
The  first  eight  pages  of  a  work  with  this  title,  has  been  sent  to  us. 
From  the  range  of  words  as  exhibited  in  the  specimen,  the  work,  if  carried 
out  in  the  same  way,  will  be  very  comprehensive.  Such  a  work,  if  correct, 
will  be  exceedingly  valuable,  but  much  will  depend  on  the  care  of  the  au- 
thor in  sifting  authorities,  as  in  no  character  of  chemical  substances  do 
writers  more  often  disagree  than  in  that  of  solubility.  "We  observe  a  great
