sented  in  an  unusually  clear  and  readable  manner  the  fundamental 
facts  and  theories  of  physiological  chemistry.  The  following  sub- 
jects are  considered:  (i)  the  nutrients  and  related  substances;  (2) 
ferments  and  digestive  processes;  (3)  the  chemistry  of  the  tissues 
and  secretions  of  the  body;  (4)  the  end  products  of  metabolism, 
including  excretions  and  energy  balance. 
In  this  revision  a  number  of  important  changes  have  been  made. 
In  a  number  of  chapters,  notably  in  the  consideration  of  proteins, — 
the  newer  work  has  been  included.  "  A  much  fuller  discussion  has 
been  given  to  the  subject  of  the  urine,  and  a  new  chapter  has  been 
added  on  the  methods  of  urine  analysis.  These  methods  embrace 
not  only  the  usual  clinical  tests,  but  the  most  important  quantita- 
tive processes,  in  certain  directions,  as  well,  and  are  given  in  suffi- 
cient detail  for  practical  metabolism  work." 
Many  experiments  are  included  in  the  book,  and  while  it  is 
primarily  intended  for  the  use  of  scientific  schools,  where  prepara- 
tion for  a  medical  course  is  given,  and  for  chemical  courses  in  med- 
ical schools,  it  would  prove  a  very  valuable  book  for  postgraduate 
work  in  pharmaceutical  colleges  and  schools.

This  is  a  good  compilation  and  will  be  very  useful  in  connection 
with  a  laboratory  course  in  bacteriology.  In  the  first  part  a  general 
consideration  of  bacteriology  is  given,  together  with  a  fairly  good 
treatment  of  the  technic  involved.  In  Part  II  are  considered :  non- 
pathogenic bacteria ;  pathogenic  bacteria ;  pathogenic  bacteria  for 
animals  but  not  for  man ;  yeasts  and  moulds ;  the  examination  of 
air,  soil,  and  water;  bacteriologic  examination  of  the  organs  and 
cavities  of  the  human  body ;  and  finally  antiseptics  and  antisepsis.
