the  retail  pharmacist  very  often  is  in  need  of.  As  with  the  preced- 
ing volumes  so  in  the  present  volumes  there  are  a  number  of  eminent 
contributors.  Dr.  G.  Barger,  of  London,  has  written  the  mono- 
graphs upon  "Vegetable  Alkaloids"  and  "Ptomaines  or  Putrefaction 
Bases" ;  Dr.  E.  Frankland  Armstrong,  of  Reading,  England,  con- 
tributes the  chapter  on  "Glucosides" ;  Mr.  G.  C.  Jones,  of  London, 
is  the  responsible  editor  for  the  article  on  "Non-Glucosidal  Bitter 
Principles" ;  Dr.  A.  E.  Taylor,  of  Philadelphia,  has  written  the 
monograph  on  "Animal  Bases" ;  Dr.  J.  A.  Mandel,  of  New  York 
City,  is  the  author  of  the  article  on  "Animal  Acids" ;  Mr.  Davis,  of 
Harpenden,  England,  has  written  the  monograph  upon  "Lactic 
Acid";  and  the  final  chapter  upon  "Cyanogen  and  its  Derivatives" 
represents  the  work  of  Mr.  Herbert  Philipp,  Perth  Amboy,  New 
Jersey. 
The  text  is  illustrated  with  drawings  of  several  of  the  substances 
occurring  in  a  crystalline  condition.  This  portion  of  the  work 
might  well  be  extended  although  it  is  likely  that  chemists  usually 
pay  very  little  attention  to  the  forms  of  crystals  of  pure  substances. 
The  references  to  the  literature  of  original  articles  is  quite  extended 
and  for  all  practical  purposes  will  be  found  to  be  sufficient.  Some 
of  the  articles  are  very  complete  and  likely  to  be  of  very  great 
service  at  the  present  time.  The  article  on  "  lecithins,"  and  in  fact 
the  whole  chapter  on  "animal  bases"  has  been  presented  particularly 
well.  Owing  to  the  interest  in  lactic  acid  and  its  derivatives  this 
chapter  also  is  likely  to  be  frequently  consulted  and  the  information 
applied  practically. 
Chloride  of  Lime  in  Sanitation.  By  Albert  H.  Hooker. 
New  York:   John  Wiley  &  Sons,  1913. 
As  has  been  already  pointed  out  in  this  Journal  (1905,  vol.  77, 
pp.  265-281 ;  1906,  vol.  78,  pp.  140-144)  emergency  methods  for  the 
purification  of  drinking  water,  as  (when  contamination  is  beyond 
control),  are  very  much  needed.  Such  methods  are  likely  to  be  of  a 
more  or  less  chemical  nature.  Chlorine  has  lately  been  largely  ad- 
vocated and  is  quite  extensively  used.  The  present  book  contains 
a  vast  amount  of  information  on  the  use  of  chloride  of  lime  In 
sanitation.  There  are  also  more  than  400  abstracts  of  important 
articles  with  references  to  the  original  literature.
