The  collection  of  notes,  for  the  author  disclaims  any  pretensions 
to  completeness  as  a  treatise,  covers  an  unusually  wide  and  enter- 
taining range  of  topics,  as  will  be  evidenced  by  the  following  list  -of 
chapter  headings: 
Alcoholic  Liquors,  Antiquities,  Blood  Stains,  Building  Materials, 
Bullets  and  Other  Projectiles  from  Firearms,  Clothing,  Counterfeit 
Coins,  Damage  to  Crops,  Documents,  Dust  and  Dirt,  Explosives 
and  Explosions,  Fibres,  Finger  Prints,  Fires,  Firearms,  Foods  and 
Drugs,  Gold  and  Silver  Wares,  Haschisch,  Poisons,  Pollution  of  Water 
by  Sewage,  Robbery  from  Letters  and  Parcels,  Stains  and  Marks, 
Strong  and  Rope,  Textile  Fabrics,  Tobacco,  Traps  for  Criminals. 
There  is  an  introduction  containing  much  valuable  practical 
information  and  advice  concerning  the  reception  of  the  article,  the 
records  necessary  to  be  made,  the  manner  of  reporting  results  and 
the  facts  bearing  upon  the  subject  in  general. 
Throughout  the  entire  book  the  author  has  drawn  upon  the 
information  available  from  his  personal  experience  and  quotes 
freely  and  interestingly  from  his  case  records.  Some  of  the  data 
and  descriptions  have  a  markedly  oriental  flavor  as  might  be  expected 
from  an  author  whose  experience  has  been  largely  gained  in  Egypt. 
A  valuable  feature  of  the  book  is  the  bibliography  to  be  found  in 
connection  with  each  monograph  or  chapter.  While  admittedly 
incomplete  it  nevertheless  contains  titles  and  references  not  often 
seen. 
The  author's  style  is  facile  and  expressive.  His  material  is 
entertaining,  besides  being  valuable.  Some  of  the  monographs  are 
as  interesting  as  episodes  in  the  career  of  the  mythical  Sherlock 
Holmes  and  the  only  fault  one  has  to  find  with  the  book  is  that  it  is 
too  brief. 
It  is  a  valuable  contribution  to  forensic  chemistry  and  will 
undoubtedly  be  consulted  by  many  scientific  experts  for  data  not 
to  be  found  elsewhere.  C.  H.  LaW. 
AnnuaIv  Reports  of  the  Chemical  Laboratory  of  the  Ameri- 
can Medical  Association,  Volume  12. — This  is  another  valuable 
report  emanating  from  the  Chemical  Laboratory  of  the  American 
Medical  Association.  It  again  emphasizes  the  important  functions 
of  this  adjunct  to  the  A.  M.  A.  established  in  1906  and  the  value  of 
the  service  rendered  thereby.
