Textbook  of  Pastor ai,  and  Agricultural  Botany.  By  John 
W.  Harshberger,  Ph.D.,  Professor  of  Botany,  University  of 
Pennsylvania.  XIII.  294  pages  and  index,  121  illustrations. 
P.  Blakiston's  Son  and  Co.,  Philadelphia. 
This  interesting  book,  small  in  size  though  comprehensive  in 
subjects  considered,  is  from  the  pen  of  a  teacher  whose  long  ex- 
perience in  imparting  botanical  knowledge  to  students  of  general  and 
professional  courses  has  indicated  what  is  most  essential  in  economic 
botany,  for  readers  to  whom  the  text  is  particularly  directed,  namely, 
stock  raisers,  veterinarians  and  agriculturalists. 
Its  contents  are  grouped  under  eighteen  chapters,  as  follows: 
I.  Stock-killing  Plants.  2.  Poisoning  by  Plants.  3.  Poisonous 
Fungi  and  other  Spore-bearing  Plants.  4.  Gymnospermous 
Poisonous  Plants.  5.  Monocotyledons  as  Poisonous  Plants.  6.  Di- 
cotyledons as  Poisonous  Plants.  7.  Loco  Weeds  and  other  Poisonous 
Plants.  8.  Miscellaneous  Dicotyledonous  Plants.  9.  Principally 
Solanaceous  and  Compositous  Plants.     10.   Feeds  and  Feeding. 
II.  The  Structure  and  Generar  Economic  Importance  of  Grasses. 
12.  Description  of  Important  Grass  Forage  Plants.  13.  The  Most 
Important  American  Cereals.  14.  General  Characteristics  of  the 
Leguminosae.    15.  The  Forage  Plants  of  the  Family  Leguminosae. 
16.  Leguminous  Root  Tubercles  and  the  Accumulation  of  Nitrogen. 
17.  Weeds  and  Weed  Control.  18.  Agricultural  Seeds,  Seed  Selec- 
tion and  Testing. 
Accompanying  each  chapter  is  a  representative  bibliography 
together  with  laboratory  exercises  and  methods  of  utilizing  the 
illustrative  material  mentioned. 
In  those  portions  of  the  text  dealing  with  various  poisonous 
plants  a  short  description  of  the  plant  and  its  distribution  is  given. 
This  is  followed  by  the  symptoms  and  treatment  of  the  animals 
poisoned. 
Many  of  the  poisonous  plants  considered  are  those  which  are  not 
usually  found  in  textbooks  of  materia  medica  and  toxicology,  nor  in 
the  pharmaceutical  journals  which  the  average  pharmacist  receives. 
Another  useful  feature  of  the  book  from  the  viewpoint  of  a 
pharmacist  is  the  data  contained  in  the  chapter  on  Weeds  and  Weed 
Control.  The  pharmacist,  being  the  one  individual  in  the  com- 
munity mostly  consulted  on  these  matters,  will  find  the  information 
contained  in  this  particular  chapter  quite  profitable.
