found  throughout  the  vegetable  kingdom;"  on  p.  121,  that  "  microchemically, 
acids  have  no  effect  on  calcium  oxalate;"  all  of  which  statements  are  more  or 
less  misleading. 
Also,  on  p.  126,  a  drawing  of  a  root-tip  is  given,  and  the  axial  part  is  pointed 
out  as  the  periblem,  and  the  zone  exterior  to  this  as  the  plerome,  which  is  not  in 
accord  with  such  excellent  authorities  as  Strasburger  and  Vines,  nor  with  what 
Dr.  Rusby  says  in  the  first  part  of  this  same  book. 
In  the  accompanying  text,  on  p.  127,  the  following  statement  occurs:  "Be- 
neath  this  (that  is  the  dermatogen )  lies  the  plerome  which  gives  rise  to  the  fibro- 
vascular  system,  and  within  is  the  periblem,  from  which  the  ground  tissues 
arise."  (The  italics  are  ours.)  This  statement  renders  confusion  worse  con- 
founded. All  of  this  shows  that  in  Part  II  the  proof-reading  was  less  carefully 
done  than  it  ought  to  have  been,  a  defect  which,  it  is  to  be  hoped,  a  second 
edition  will  rectify. 
This  part  is  also  copiously  illustrated  and  the  drawings  are  good,  though  it  is 
to  be  regretted  that  the  author  has  been  obliged  to  credit  nearly  all  of  these  to 
German  authors,  instead  of  giving  us  original  ones.

A  Study  in  Pharmacy.    By  J.  U.  Lloyd.    Cincinnati,  O.,  1894. 
Something  over  a  year  ago,  Professor  Lloyd  commenced  mailing  to  his  friends 
the  pages  of  a  work  that  at  first  was  decidedly  a  puzzle  to  them.  The  first  part 
issued  was  entitled  "  Preliminary,"  the  second  part  "  Generalities;"  these  occu- 
pied over  two  fasciculi,  and  then  the  subject  of  "  Experimentation  "  was  taken 
up.  Later, "  Chemical  and  Pharmacal  Compounds  "  were  discussed,  but  still  the 
plan  and  object  of  the  work  were  not  apparent. 
More  recently,  the  author  has  thrown  some  light  on  the  drift  of  the  work  by 
discussing  the  less  comprehensive  subject,  "Capillarity."  This  subject  he  has 
commenced  with  a  short  outline  of  study,  and  then  follows  an  elaborate  list  of 
references  to  the  literature  of  capillarity.  This  index  commences  with  the 
year  1452,  and,  up  to  this  writing,  it  has  reached  the  year  1857,  with  222  sepa- 
rate references.  If  the  author  completes  this  valuable  reference  list,  which  he 
has  copiously  amplified  with  brief  abstracts,  he  will  confer  a  lasting  benefit  on 
all  those  who  have  occasion  to  pursue  this  interesting  study. 
We  hope  these  contributions  will  continue  to  reach  us  in  rapid  succession. 
The  Principles  and  Practice  oe  Agricultural  Analysis.  Volume  II, 
Fertilizers.  By  Harvey  W.  Wiley.  Easton,  Pa. :  Chemical  Publishing  Com- 
pany. 1895. 
The  first  volume  of  this  work  was  devoted  to  soils,  and  was  reviewed  in  this 
Journal  just  one  year  ago.  It  was  then  thought  that  the  second  volume 
would  complete  the  work;  but  the  author  found  that  the  subject  of  fertilizers 
alone  made,  with  index,  332  pages,  so  it  was  decided  to  start  a  new  volume, 
which  is  now  coming  out  in  monthly  parts. 
Volume  II  is  divided  into  four  parts  :  Part  I  is  devoted  to  "  Phosphates  and 
Phosphatic  Fertilizers  ;"  Part  II  considers  "Nitrogen  in  Fertilizers  and  Fertil- 
izing Materials  ;"  Part  III  treats  of  "Potash  in  Fertilizing  Materials  and  Fer- 
tilizers ;"  and  Part  IV  concludes  with  a  survey  of  "  Miscellaneous  Fertilizers." 
The  analytical  side  of  the  subject  is  very  fully  discussed,  and  illustrated  with 
very  practical  apparatus.     To  the  chemist  this  volume  will  be  of  even  more
