volumetric  solutions  for  medico-chemical  examinations.  This  is  one 
of  the  most  commendable  features  of  this  revision  and  places  in  a 
compact  schedule  these  reagents  and  tests  and  should  prove  a  valua- 
ble aid  to  the  busy  practitioner  or  pharmacist.  The  classification  here 
is  according  to  the  subjects  of  investigation,  the  first  sub-heading 
being  the  reagents  for  urine  analysis,  and  this  is  sub-divided  under 
paragraph  headings  directions  for  albumin,  for  sugar,  for  pentoses, 
for  acetone,  for  acetic  acid,  for  urobilin,  for  urobilinogen,  for  gall 
coloring  matters,  for  indican,  for  carrying  out  the  diazo  reaction,  for 
iodine,  for  salicylic  acid  and  for  blood.  The  second  classification 
is  for  the  investigation  of  stomach  contents.  The  third  for  the 
examination  of  blood.  The  fourth  is  for  the  examination  for  bac- 
teria and  protozoa,  and  here  formulas  are  given  for  the  necessary 
stains  and  reagents  and  the  standards  are  here  given  for  the  cedar 
oil,  Canada  balsam  and  xylol  suitable  for  microscopic  investigations. 
Another  chapter  of  the  appendix  is  a  table  of  specific  gravities 
of  the  official  liquids  at  temperatures  from  12°  to  25°.  Although 
doses  are  given  with  each  monograph  or  formula  in  the  body  of  the 
book,  a  table  of  maximum  doses  for  adults  is  given  in  the  appendix. 
Another  table  is  devoted  to  a  list  of  the  deadly  poisons  that  must 
be  kept  under  lock  and  dispensed  with  great  caution.  Still  another 
table  is  devoted  to  other  less  poisonous  or  dangerous  medicaments 
that  one  should  beware  of.  An  extensive  list  of  synonyms  and 
less  used  names  is  one  of  the  important  tables  included  in  the 
appendix. 
THE  LACTIC  ACID  ESTER  OF  SANTALOL  AND  OTHER 
SANTALOL  COMPOUNDS.^ 
By  Frederic  S.  Mason,  B.Sc,  Ph.G.,  M.D.,  New  York. 
I  should  have  liked  to  have  introduced  the  subject  of  my  paper 
by  a  short  review  of  the  history  of  sandalwood  and  its  oil,  for 
with  ambergris  and  musk,  sandalwood  is  one  of  those  natural 
products  used  from  very  remote  ages  in  perfumery  and  medicine. 
I  have  been  interested  in  sandalwood  for  over  twenty-five  years, 
having  been  one  of  the  first  to  make  an  investigation  of  the  sources 
of  supply  in  India,  Malaysia,  Timor  and  Western  Australia,  which 
countries  I  visited  on  two  occasions  for  the  specific  purpose  of 
determining  the  cause  of  the  variations  observed  in  the  laboratory,
