Practical  Physiological  Chemistry. — A  Book  Designed  for 
Use  in  Courses  in  Practical  Physiological  Chemistry  in  Schools  of 
Medicine  and  of  Science.  By  Philip  B.  Hawk,  M.S.,  Ph.D.,  Pro- 
fessor of  Physiological  Chemistry  in  the  University  of  Illinois. 
Second  edition,  revised  and  enlarged.  Philadelphia:  P.  Blakiston's 
Son  &  Co.,  1012  Walnut  St.,  1909.   $2.50  net. 
Hawk's  text-book  on  physiological  chemistry  is  one  of  the  most 
valuable  books  on  this  subject.  It  contains  a  large  amount  of 
information  representing  the  most  recent  researches  in  this  line 
of  investigation.  The  illustrations  are  numerous,  frequently  in 
colors,  well  selected,  and  will  prove  of  great  advantage  to  the 
student.  Subjects  treated  by  the  author  include :  enzymes  and  their 
action ;  carbohydrates ;  salivary  digestion ;  proteins ;  gastric  diges- 
tion ;  fats  ;  pancreatic  digestion ;  bile ;  putrefaction  products ;  faeces ; 
blood ;  milk ;  epithelial  and  connective  tissues ;  muscular  tissue ; 
nervous  tissue;  urine;  and  quantitative  analysis  of  milk,  gastric 
juice,  and  blood. 
The  work  will  be  found  of  inestimable  value,  not  only  to  the 
student  of  physiological  chemistry  but  also  to  the  analyst  of  patho- 
logical products.  In  fact  it  might  be  said  that  a  course  as  outlined 
in  this  work  should  always  precede  the  course  in  urinalysis,  blood 
examination,  and  toxicological  analysis,  etc.,  whether  given  in  med- 
ical or  pharmaceutical  colleges. 
The  Urine,  the  Gastric  Contents,  the  Common  Poisons, 
and  the  Milk.  By  J.  W.  Holland,  M.D.,  Professor  of  Medical 
Chemistry  and  Toxicology,  Jefferson  Medical  College  of  Philadel- 
phia.   Philadelphia :  P.  Blakiston's  Son  &  Co. 
This,  the  eighth  edition  of  Holland's  well-known  work,  has  been 
revised  and  enlarged,  and  is  too  well  known  to  require  an  extended 
review.  It  is  a  very  popular  book  among  students  and  is  frequently 
purchased  by  them  even  when  it  is  not  the  prescribed  text-book  fol- 
lowed in  the  course  of  instruction.
