the  preceding  volumes,  a  large  number  of  valuable  articles.  Among 
these  maybe  mentioned:  "Rheumatism,"  by  F.  Levison ;  "  Dis- 
eases of  the  Stomach,"  by  D.  D.  Stewart ;  "  Surgery  of  the  Stomach 
and  Intestines,"  by  W.  W.  Keen  and  M.  B.  Tinker ;  "  Surgery  of  the 
Spine,"  by  R.  H.  Sayre;  "Syphilis,"  by  G.  F.  Lydston ;  "  Surgery 
of  the  Urinary  System,"  by  J.  W.  White  and  A.  C.  Wood;  "Dis- 
eases of  the  Uterus,"  by  H.  T.  Byford  ;  "Diseases  of  the  Uterine 
Adnexa,"  by  E.  E.  Montgomery;  Wounds  and  Injuries  of  the 
Chest,"  by  L.  A.  Stimson  and  E.  L.  Keyes,  Jr.,  and  "  Yellow 
Fever,"  by  W.  Wyman. 
These  remarkable  books  are  probably  not  duplicated  in  medicine, 
as  they  contain  not  only  what  is  usual,  in  books  on  practice  of 
medicine,  but  considerable  space  is  devoted  to  surgical  subjects. 
The  progress  of  the  past  decade  is  recorded  and  in  many  instances 
original  work  was  instituted  to  solve  the  problems  that  the  research 
workers  had  not  as  yet  attempted.  The  various  specialties  have  re- 
ceived consideration,  the  newer  the  rapeutics  has  been  introduced 
and,  in  short,  everything  has  been  done  to  make  the  work  an  origi- 
nal, valuable  and  advanced  encyclopaedia  of  the  entire  field  of  practical 
medicine.  The  general  index  accompanying  this  volume  is  a  model 
of  its  kind,  and  illustrates  how  much  matter  is  usually  lost  sight  of  in 
the  encyclopaedic  works  because  of  this  lack  of  systematic  arrange- 
ment. There  have  been  few  books  so  ably  edited,  so  full  of  infor- 
mation, and  so  arranged  that  every  subject  on  which  information  is 
desired  may  be  readily  consulted. 
Notes  on  Equation  Writing  and  Chemical  and  Pharmaceu- 
tical Arithmetic.  Second  edition,  revised  and  enlarged.  By  J. 
H.  Beal.    Pittsburg:  The  Calumet  Publishing  Company. 
The  first  edition  of  this  book  was  published  by  the  author  for  the 
benefit  of  his  students,  without  any  thought  of  a  more  extended  cir- 
culation. But  as  with  all  books  on  such  subjects,  if  there  is  any- 
thing to  commend  them,  they  are  likely  to  be  used  in  a  much  wider 
sphere  than  is  anticipated.  This  is  the  case  with  Beal's  "  Equation 
Writing  and  Chemical  and  Pharmaceutical  Arithmetic."  The  work 
is  a  good  pharmaceutical  stoichiometry,  and  the  chapters  on  equa- 
tion writing  will  make  the  work  of  such  value  that  it  will  doubt- 
less replace  Barker's  "  Chemistry,"  for  this  purpose,  which  has  so 
long  been  used  by  students  beginning  the  study  of  chemistry.
