Manual  of  Chemistry.  By  W.  Simon,  Ph.D.,  M.D.  Fifth  edition.  Phila- 
delphia, Lea  Bros.  &  Co.  1895. 
The  demand  for  this  work  has  necessitated  the  issue  of  another  edition,  and 
the  author  has  taken  the  opportunity  to  thoroughly  revise  it  and  bring  it  in 
complete  harmony  with  the  new  Pharmacopoeia.  The  orthography  recom- 
mended by  the  American  Association  for  the  Advancement  of  Science  has  not 
been  fully  adopted,  for  the  reason  that  neither  the  leading  chemical  journals 
nor  the  United  States  Pharmacopoeia  use  this  spelling,  and  that  it  would  be 
unwise  to  have  the  student  confronted  with  two  different  systems  of  orthogra- 
phy. The  foregoing  statements  of  the  author  we  can  heartily  endorse;  the  stu- 
dent should  not  be  confronted  with  any  more  systems  in  anything  than  are 
absolutely  necessary,  least  of  all  in  the  every-day  matter  of  spelling.  Let  the 
Pharmacopoeia  lead. 
What  has  been  said  of  Dr.  Simon's  standard  work  in  previous  pages  of  this 
journal,  we  can  fully  subscribe  to,  and  we  can  especially  commend  the  unique 
colored  plates,  representing,  as  they  do,  sixty-four  chemical  reactions.  One 
new  plate  has  been  added  to  the  present  edition,  showing  the  chemical  behavior 
of  a  number  of  the  more  important  benzene  derivatives. 
SwEET  Cassava  :  Its  Culture,  Properties  and  Uses.  By  Harvey  W.  Wiley. 
Bulletin  No.  44,  U.  S.  Department  of  Agriculture,  Division  of  Chemistry. 
An  abstract  of  this  interesting  and  valuable  contribution  will  be  given  in  a 
future  number. 
Etidorhpa,  or  The  End  of  the  Earth.  The  Strange  History  of  a  Mys- 
terious Being,  and  the  Account  of  a  Remarkable  Journey,  as  Communicated  in 
Manuscript  to  Llewellyn  Drury,  who  promised  to  print  the  same,  but  finally 
evaded  the  responsibility,  which  was  assumed  by  John  Uri  Lloyd.  With  many 
illustrations  by  J.  Augustus  Knapp.  Author's  edition,  limited.  Cincinnati, 
John  Uri  Lloyd.  1895. 
We  have  been  allowed  to  see  some  proof-sheets  of  a  work  which  is  destined 
to  figure  conspicuously  in  the  literature  of  both  science  and  romance. 
Professor  Lloyd  is  well  and  favorably  known  as  an  experimenter  and  a  writer 
on  scientific  subjects  relating  to  pharmacy,  but  it  will  surprise  some  of  his 
friends  to  know  that  he  now  appears  in  the  role  of  philosopher  and  romancer. 
If  it  is  feared  by  any  one  that  the  author,  in  assuming  such  a  difficult  part,  has 
impaired  his  faculties  for  writing  on  pharmaceutical  subjects,  we  venture  to 
convince  them  of  the  contrary  by  pointing  to  his  valuable  paper  on  distilled 
water,  which  appears  on  p.  190,  of  this  number  of  the  Journal,  and  which 
was  prepared  by  him  since  his  "  Etidorhpa  "  went  to  press. 
As  we  have  not  the  whole  work  we  reserve  our  decision,  but  feel  safe  in  saying 
that  it  will  be  intensely  interesting  and  at  the  same  time  instructive.
