not,  which  is  intentionally  added  to  another  substance,  and  condemns  the  pre 
texts  under  which  some  of  these  practices  occasionally  seek  justification,  as 
untenable.  Why  should  not  the  consumer  improve  the  color  or  flavor  to  suit 
his  individual  taste  ?  and  does  not  the  manufacturer  look  rather  to  his  owe 
gain  than  to  the  interests  of  the  consumer?  We  heartily  approve  of  these 
views,  which,  though  they  may  be  considered  radical,  are  nevertheless  correct, 
and  merit  the  careful  attention  of  all  who  knowingly  deal  in  such  "  made  up  " 
articles.  Accidental  impurities,  and  such  which  occur  in  consequence  of  a 
faulty  process  in  their  preparation,  are  not  regarded  in  the  light  of  falsifica- 
tions. 
After  giving  a  list  of  works  published  in  different  languages,  with  the  view 
of  aiding  in  the  examination  of  drugs  and  other  articles  for  impurities  and 
sophistications,  the  various  means,  apparatus,  reagents  and  processes  are  briefly 
described,  and  afterwards,  in  alphabetical  order,  the  drugs  and  other  substances, 
together  with  such  impurities,  additions  and  substitutions  which  have  more  or 
less  frequently  been  observed.  Whenever  it  has  been  deemed  necessary,  illus- 
trations have  been  introduced,  many  of  which,  giving  views  under  the  micro- 
scope, have  been  selected  from  Hassall's  well-known  work  on  adulterations. 
The  description  of  each  article  under  consideration  is  given  in  a  brief  manner, 
viewing  mainly  those  characteristics  which  are  requisite  for  determining  the 
identity,  and  afford  points  of  comparison  useful  in  recognising  foreign  bodies ; 
the  latter  are  then  described  and  the  differences  pointed  out.  In  many  cases, 
a  list  of  the  most  important  publications  is  added,  treating  specially  or  in  de- 
tail of  the  admixtures  in  question. 
Throughout  the  work  the  author  has  availed  himself  of  the  literature  on  this 
special  subject  not  only  contained  in  works  devoted  to  this  object,  but  likewise 
to  that  which  is  scattered  throughout  the  periodicals  published  in  different 
languages ;  and  wherever  special  processes  or  observations  are  cited,  the  name 
of  their  authors  or  observers  is  likewise  given. 
In  an  appendix,  abstracts  of  laws  of  France,  England,  Belgium,  Holland, 
Germany,  Switzerland  and  Italy  are  given,  which  have  been  enacted  with  the 
view  of  preventing  or  punishing  such  frauds. 
The  work  is  creditable  to  its  author,  showing  extensive  reading,  close  obser- 
vation, and  careful  selection.  The  typographical  portion  is  well  executed,  and 
most  illustrations  are  clear,  easily  understood,  and  of  direct  value  to  the  aim 
and  object  of  the  work.

The  first  volume  of  this  dictionary,  which  appeared  nearly  two  years  ago, 
was  the  French-German-English  part;  the  third,  or  German-French-English, 
has  been  promised  for  the  coming  year. 
It  is  a  most  valuable  work,  exhibiting  a  vast  amount  of  research,  and  an
