and  considerable  useful  information  on  various  non-Official  chemical 
substances,  as  well  as  articles  of  the  vegetable  materia  medica. 
Nearly  three  hundred  pages  are  devoted  to  the  discussion  of  the 
various  pharmaceutical  operations,  as  distillation,  solution,  filtration, 
percolation,  etc.  Over  two  hundred  pages  are  given  to  the  consid- 
eration of  magistral  or  extemporaneous  pharmacy,  this  part  having 
been  enlarged  by  the  addition  of  a  new  chapter  on  "  Incompatibil- 
ity," the  insertion  of  new  illustrations  of  autograph  prescriptions 
and  numerous  new  cuts  of  apparatus,  together  with  descriptions  of 
the  same. 
There  are  certain  inaccuracies  in  the  book  which  are  of  a  techni- 
cal or  scientific  nature,  and  while  they  are  not  likely  to  interfere  with 
the  usefulness  of  the  book  as  a  working  guide,  mar  it  to  a  certain 
extent  when  considered  as  a  work  of  reference.  Under  Linum  (p.  749) 
it  is  stated  that  the  fixed  oil  is  "  in  the  nucleus."  While  the  term 
"  nucleus  "  was  used  at  one  time  to  designate  the  kernel  of  a  seed,  it 
is  now  limited  entirely  to  one  of  the  organized  bodies  of  the  cell. 
The  distinction  between  starch  and  inulin  given  on  page  744  is  not 
entirely  correct.  "  StylidacecB  "  (p.  744)  should  be  "  Stylidiacece"  or 
better,  " Candolleacece"  Canna  (p.  744),  instead  of  belonging  to 
the  Matantaccce,  is  now  classed  as  a  member  of  the  Cannacece. 
"  Protococcus  vulgaris"  (p.  752)  should  be  "  Pleurococcus  vulgaris" 
"  Calamintlia  c/i/iopodium"  (p.  813)  should  be  "  Kceilia  incana." 
Bael  fruit  (p.  750)  belongs  to  the  Rutaccce  and  not  to  Aurantiacece, 
as  stated.  These  references  are  probably  sufficient  to  indicate 
some  of  the  improvements  which  might  be  made  in  a  future  edition. 
Bacteria  in  Relation  to  Plant  Diseases.  By  Erwin  F.  Smith, 
i  1  charge  of  Laboratory  of  Plant  Pathology,  Office  of  Physiology 
and  Pathology,  Bureau  of  Plant  Industry,  United  States  Department 
of  Agriculture.  Volume  I.  Methods  of  work  and  general  literature 
of  bacteriology,  exclusive  of  plant  diseases.  Washington,  D.  C. : 
Published  by  the  Carnegie  Institution  of  Washington,  September, 
1905. 
Dr.  Smith  ranks  as  one  of  the  foremost  bacteriologists  of  the  day, 
and  he  is  rendering  science  a  distinct  service  in  giving  not  only  the 
results  of  his  own  researches  and  experience  for  the  last  fifteen 
years,  but  also  those  gained  by  extensive  reading  and  searching  of 
literature,  in  the  volumes  which  are  to  constitute  this  work,  the  first
