These  contributions  are  of  the  same  high  order  that  we  are  accus- 
tomed to  see  in  these  volumes,  and  are  highly  appreciated  by  sys- 
tematic botanists  and  students  of  morphological  botany.  Each  mono- 
graph is  beautifully  illustrated  and  contains  a  rather  comprehensive 
bibliographical  index. 
E.  Merck's  Annual  Report  of  Recent  Advances  in  Pharma- 
ceutical Chemistry  and  Therapeutics.  1913  :  volume  xxvii. 
E.  Merck,  Chemical  Works,  Darmstadt,  1914. 
This  volume  continues  to  be  a  veritable  vade  mecum  of  informa- 
tion concerning  medicinal  substances.  In  the  present  volume,  follow- 
ing the  precedent  already  established,  there  are  2  extended  mono- 
graphs, the  one  on  nuclein  and  nucleinic  acid,  and  the  other  on  prep- 
arations used  for  radiographic  examination.  There  are  nearly  500 
pages  devoted  to  the  consideration  of  preparations  and  drugs,  which 
are  greatly  enhanced  by  the  addition  of  a  General  Index,  Index  of 
Diseases,  Symptoms  and  Indications  for  Treatment,  Index  of 
Authors,  and  a  Bibliographical  Index.
