384  Reviews  and  Bibliographical  Notices.  {Ami^m™m- 
maceutical  Association.  Tables  showing  the  relation  of  weights  and  meas- 
ures, an  index  of  diseases,  and  a  general  index  take  up  the  remaining 
pages. 
Like  the  preceding  editions,  the  present  one  will  commend  itself  to  those 
for  whom  the  work  was  originally  prepared.  It  does  not  aim  to  supersede 
more  elaborate  works  on  therapeutics ;  but  in  presenting  the  subject  in  a 
rather  brief  compass,  and  unencumbered  by  botanical,  chemical  and  phar- 
maceutical detail,  it  will  continue  to  serve  a  very  useful  purpose  as  a  handy 
reference  book  on  therapeutics  and  materia  medica. 
Der  Kohlensdure-Gehalt  der  Luft  in  und  bei  Dorpat,  bestimmt  in  den  Monaten 
September,  1888,  bis  Januar,  1889.    Von  Eugen  von  Frey.    Pp.  49. 
The  amount  of  carbonic  acid  in  the  atmosphere  of  and  near  Dorpat  from 
September,  1888,  to  January,  1889.  A  continuation  of  the  work  by  J.  Hei- 
mann,  which  was  noticed  on  page  271. 
Vergleichende  Untersuchungen  der  ivichtigeren  zum  Nachweise  von  Arsen  in  Tape- 
ten  und  Gespinnsten  empfohlenen  Methoden.  Von  Nicolai  Jorban.  Pp.  71. 
Comparative  examination  of  the  more  important  methods  recommended 
for  the  detection  of  arsenic  in  wallpapers  and  textile  materials. 
The  methods  recommended  by  DragendorfF,  Thorns,  Lyttkens,  Schmelck, 
Fluckiger,  Reichard,  and  Fleck  have  been  examined ;  also  those  prescribed  for 
the  above  purpose,  by  law,  in  Sweden  and  in  Germany.  Since  exceedingly 
minute  quantities  of  arsenic  are  readily  detected,  and  since  this  metal  is 
widely  distributed  in  nature,  the  absolute  freedom  from  arsenic  of  the  above 
articles  cannot  be  expected  in  all  cases  ;  hence  the  importance  of  the  deter- 
mination of  the  limits  allowable  without  injury  to  the  human  health. 
Die  officinellen  Oroton-  und  Diosmeen-Rinden  der  Sammlung  des  Dorpater 
Pharmaceutischen  Institutes.  Von  Friedrich  Lichinger.    Pp.  52. 
The  officinal  barks  of  croton  and  diosmeae  in  the  collection  of  the  Pharma- 
ceutical Institute  of  Dorpat. 
The  investigation  comprises  barks  like  cascarilla,  copalchi,  malambo, 
angustura  and  allied  (esenbeckia)  barks.  Aside  from  the  local  interest  at- 
tached to  the  careful  examination  of  the  specimens,  the  pamphlet  is  quite 
valuable  on  account  of  the  extensive  literature  on  these  subjects,  which  has 
been  collected  with  circumspection  and  critically  arranged. 
Second  biennial  Report  of  the  North  Carolina  Board  of  Health  to  the  General 
Assembly  of  North  Carolina.    Session  of  1889.  Raleigh,  1889.  8vo.;  pp.  191. 
Besides  the  report  of  the  Board  and  its  Committees,  the  pamphlet  con- 
tains also  a  number  of  papers  of  general  interest :  by  Dr.  Thos.  F.  Wood,  on 
the  causes  of  death  and  suggestions  about  the  future  of  prevention  ;  by  Dr. 
F.  P.  Venable,  on  foods  contaminated  with  metallic  poisons,  and  on  the 
quality  of  quinine,  bismuth  and  laudanum ;  by  J.  L.  Ludlow,  C.  E.,  on  the 
sewerage  of  cities  and  towns,  etc.
