The  Microscopy  of  Technical  Products.  By  T.  F.  Hanausek. 
Kevised  by  the  author  and  translated  by  Andrew  L.  Winton  with 
the  collaboration  of  Kate  G.  Barber.  With  276  illustrations.  8vo., 
xii  and  471  pages,  276  figures.  Cloth,  $5.  New  York  :  John  Wiley 
&  Sons.    London  :  Chapman  &  Hall,  Limited.  1907. 
It  is  very  fortunate  for  American  students  of  technical  products 
that  Dr.  Winton  and  Dr.  Barber  have  taken  the  pains  to  translate 
^he  valuable  text-book  of  Hanausek.  The  translation  has  been  car- 
ried out  with  the  cordial  co-operation  of  the  author.  "  Much  new 
matter  has  been  added  to  the  chapters  on  textile  fibers,  and  the 
number  of  practical  examples  increased  from  eight  to  eighteen. 
The  analytical  key  for  woods  has  been  revised  so  as  to  include  the 
most  important  North  American  species."  A  number  of  cuts  in 
the  German  edition  have  been  dropped  but  nearly  fifty  other  illus- 
trations have  been  added. 
The  work  consists  of  the  following  chapters  :  1,  The  Microscope  ; 
2,  Microscopic  Accessories ;  3,  Microtechnique  and  Reagents ;  4, 
Starch  and  Inulin  ;  5,  Vegetable  Fibers  and  the  Microscopic  Ex- 
amination of  Paper ;  6,  Animal  Fibers,  Mineral  Fibers  and  Textiles ; 
7,  Wood  of  Dicotyledons  and  Gymnosperms,  Monocotyledonous 
Stems,  Subterranean  Organs  and  Barks;  8,  Leaves;  Insect  Pow- 
der; io,  Fruits  and  Seeds,  including  Oil  Cakes;  n,  Teeth,  Bone, 
horn,  etc,  ;  12,  Microchemical  Analysis. 
The  work  is  creditable  to  the  authors  and  is  welcome  to  analysts 
and  students  of  technical  products.  It  is  a  reliable,  scientific  guide 
to  the  student  and  of  great  value  to  the  investigator  of  raw  materials. 
Plant  Anatomy,  from  the  standpoint  of  the  development  of 
functions  ot  the  tissues  and  handbook  of  micro-technique.  By  Wil- 
liam Chase  Stevens.  With  136  illustrations.  Philadelphia;  P. 
Blakiston's  Son  &  Co.  1907. 
As  stated  by  the  author  "the  book  attempts  to  point  out  in  a 
brief  and  elementary  way  how  plants  arrive  at  this  achievement  by 
the  evolution  of  the  different  physiological  tissue  systems  from  a 
primitive  undifferentiated  embryonic  tissue,  and  how  the  tissue  sys- 
tems are  adapted  by  their  character  and  relation  to  each  other  to 
carry  out  the  plant's  vegetative  functions." 
A  very  good  idea  of  the  subjects  treated  may  be  had  from  the 
titles  of  the  seventeen  chapters:  1,  The  Plant  Cell  ;  2.  Differentia-
