addition  i  article  on  the  testing  of  quinine  pills,  5  articles  bearing  on 
phytochemical  subjects,  12  articles  of  a  general  chemical  character, 
12  articles  on  technical  and  food  products  from  the  colonies,  1  article 
describing  an  extraction  apparatus  for  a  variety  of  purposes,  and  a 
reprint  of  a  lecture  by  the  director  on  sources  of  energy  for  chemical 
processes. 
In  Europe  the  work  done  in  connection  with  the  pharmaceutical 
institute  of  the  University  of  Berlin  has  served  as  an  incentive  for 
other  institutions  to  follow  in  the  same  lines  and  work  of  a  similar 
nature  is  now  being  done  in  connection  with  the  pharmaceutical 
institutes  of  other  German  Universities,  and  also,  to  a  lesser  extent 
perhaps,  at  similar  institutions  in  Austria,  Switzerland,  France,  and 
Holland. 
With  the  interest  that  is  being  evidenced  in  the  work  of  the 
Council  on  Pharmacy  and  Ghemistry  of  the  American  Medical  Asso- 
ciation, and  the  evident  reawakening  on  the  part  of  pharmacists 
to  an  appreciation  of  the  uses  and  limitations  of  official  drugs  and 
open  formula  preparations,  we  will,  in  the  very  near  future,  no  doubt, 
witness  the  development  of  similar  work  on  the  part  of  schools  and 
colleges  of  pharmacy  in  the  United  States.  M.  I.  W. 
Handbuch  der  Pharmakognosie.  Von  A.  Tschirch.  Mit 
zahlreichen  Abbildungen  im  Text  und  auf  Tafeln  sowie  mehreren 
Karten.   Leiferung  19^21.   Leipzig  :  Chr.  Herm.  Tauchnitz. 
Beginning  with  Part  19,  we  have  the  second  part  of  Tschirch's 
Hand-book,  dealing  with  Special  Pharmacognosy.  As  the  pharma- 
cologist desires  to  know  the  nature  of  the  active  principles  of  drugs, 
Tschirch  classifies  them  according  to  their  chemical  constituents. 
The  first  group  considered  are  the  carbohydrates,  among  which  we 
find  Mel,  Flos  Verbasci,  Caricas,  Dactyli,  Passulse,  Fructus  Juniperi, 
Fructus  Sambuci,  Fructus  Pruni,  Fructus  Jujubse,  Fructus  Myrtilli, 
Fructus  Rubi  Idsei,  Radix  Liquiritse,  Manna,  Saccharum,  Amylum, 
etc.,  etc. 
Each  product  or  drug  is  considered  in  detail  as  follows :  Syno- 
nyms, etymology,  botanical  origin,  description  of  the  plant  yielding 
the  drug,  and  the  diseases  which  may  afifect  it,  cultivation,  source, 
commercial  varieties,  macroscopic  and  microscopic  description  of 
the  drug,  chemical  constituents,  adulterations,  historical  notes  con- 
cerning the  drug,  and  a  nearly  complete  citation  of  the  important 
literature.
