tains a  large  amount  of  valuable  information  and  will  be  appreciated 
by  those  who  desire  information  on  the  chemistry  of  familiar  things. 
It  might  also  be  advantageously  placed  in  the  hands  of  beginners,  as 
it  will  be  very  stimulating  to  them  in  their  studies.  The  work  con- 
tains a  large  number  of  illustrations,  many  of  which  are  drawn 
especially  for  this  work  by  Miss  Alice  H.  Sadtler.  The  paper,  print-

Laboratory  Manual  for  the  Detection  of  Poisons  and 
Powerful  Drugs.  By  Dr.  Wilhelm  Autenrieth,  authorized  transla- 
tion of  the  completely  revised  fourth  German  edition  by  William  H. 
Warren,  Ph.D.,  with  25  illustrations.  Philadelphia:  P.  Blakiston's 
Son  and  Co.  Price,  $2  net.  This  work  is  too  well  known  to  require 
an  extended  review.  The  present  volume  is  considerably  larger  than 
the  third  edition  and  has  been  entirely  revised.  Among  the  new 
substances  discussed  the  following  may  be  mentioned :  Cantharidin, 
cytisine,  ergot,  papaverine,  pilocarpine,  saponin  substances,  solanine, 
thebaine,  and  the  toxalbumins,  ricin,  abrin,  and  crotin.  In  Chapter  II 
hydrastine  and  veronal  are  elaborated.  Chapter  V  has  to  do  with 
special  qualitative  and  quantitative  methods,  such  as  the  quantitative 
estimation  of  phosphorus  in  phosphorated  oils  ;  the  electrolytic  de- 
tection and  estimation  of  arsenic  ;  the  biological  test  for  arsenic ;  the 
destruction  of  organic  matter  and  detection  of  arsenic  by  A.  Gautier 
and  G.  Lockemann ;  Karl  Th.  Morner's  estimation  of  minute  quan- 
tities of  arsenic ;  methods  of  estimating  alkaloids  by  H.  Matthes, 
H.  Thorns,  and  A.  H.  Gordin.  This  chapter  also  includes  A.  J.  J. 
Vandevelde's  estimation  of  the  toxic  action  of  organic  compounds 
by  means  of  blood  haemolysis. 
Chapter  VI  takes  up  the  estimation  of  alkaloids  and  other  active 
principles  in  raw  materials  (drugs)  and  in  their  preparations. 
Pharmacopceial  as  well  as  other  estimations,  such  as  that  of  nicotine 
in  tobacco,  caffeine  in  tea,  coffee,  kola  preparations,  etc.,  pilocarpine 
in  jaborandi  leaves,  piperine  in  pepper,  solanine  in  potatoes,  and 
theobromine  in  cacao  and  its  preparations,  have  been  included.  The
