have  also  been  considerably  amended,  so  that  in  its  present  shape  the  work 
serves  its  purpose  even  better  than  it  formerly  did ;  the  more  so  since 
the  illustrations  have  been  increased  in  number  to  nearly  six  hundred.  In 
other  respects,  we  refer  to  our  favorable  notice  of  the  first  edition,  and 
heartily  recommend  the  work  alike  to  teachers  and  student. 
Merck's  Index  of  Fine  Chemicals  and  Drugs  for  the  Materia  Medica  and  the 
Arts.    By  E.  Merck,  1889.    8vo.    Pp.  156.    Price,  $1. 
This  Index  is  a  complete  list  of  chemicals  used  at  the  present  time  in 
medicine  and  the  arts,  and  gives  for  each  the  common  name  and  the  various 
scientific  synonyms,  and  in  the  case  of  many  proximate  principles  also  their 
origin.  We  transcribe  a  few  as  examples : 
Aseptol  (ortho-Phenol-sulphonic  [ortho-Phenyl-sulphuric,  ortho-Sulpho- 
phenic,  ortho-Sulpho-carbolic]  Acid ;  ortho-Sulpho-phenol  [-carbol] — in  33J 
per  cent,  solution)  [Sozolic  Acid]. 
Manna  sugar,  Mannit  (Mannitol,  Mannol ;  Fraxinin,  Granatin;  formerly  also 
called  Punicin). 
Resorcin  (E-esorcinol ;  meta-Di-oxy-benzene). 
Cedrin  from  Cedron  seed. 
Anemonin  (Anemone-camphor,  Pulsatilla-camphor). 
Rotoin  from  Japanese  belladonna. 
It  will  be  seen  from  the  foregoing  that  this  Index  will  be  very  useful  as  a 
kind  of  dictionary  of  the  nomenclature  of  chemical  substances  used  at  the 
present  time.  Certain  pharmaceutical  preparations  are  also  included.  The 
whole  is  arranged  so  as  to  serve  as  a  price-list,  for  which  purpose  several 
blank  columns  are  found  on  each  page,  and  the  names — common  as  well  as 
synonyms — are  placed  in  alphabetical  order.  At  the  end  of  the  names 
under  each  letter  sufficient  blank  space  has  been  left  for  the  addition  of 
newly  introduced  compounds,  so  that  this  Index  in  its  present  shape  may 
retain  its  value  for  a  considerable  length  of  time. 
A  Laboratory  Guide  in  Chemical  Analysis  — By  David  O'Brine,  E.  M.,  M.  D., 
D.  Sc.,  etc.  Second  edition,  entirely  rewritten  and  revised.  New  York: 
John  Wiley  &  Sons,  1889.    8vo.    Pp.  237.    Price,  $2. 
The  eight  chapters  into  which  the  text  is  divided  refer  to  the  reagents, 
tests  in  the  dry  way,  tests  in  the  wet  way  (metals),  acids,  comparison  of 
bases  and  acids,  water  analysis,  poisons  and  general  stoichiometry.  The 
material  under  each  head  is  conveniently  arranged  for  the  use  of  the  atten- 
tive student,  and  the  instructions  given  are  brief,  but  clear,  and  as  a  rule 
ample.  The  tables  in  chap.  V.  giving  the  behavior  of  the  different  groups 
of  bases  and  acids  towards  the  principal  reagents,  might,  perhaps,  have  been 
more  conveniently  assigned  to  the  respective  groups  of  the  bases  and  acids 
in  two  preceding  chapters.  Although  the  work  is  evidently  intended  for 
students  possessing  some  knowledge  of  chemistry,  it  appears  to  us  that  the 
laudable  conciseness  of  the  text  should  not  have  prevented  the  stating  cer-
