manipulation  of  small  quantities  and  list  of  special  reagents  and 
apparatus.  Finally  there  is  an  alphabetical  index,  a  formula  index 
and  a  color  standard. 
The  entire  work  shows  care  and  patience  upon  the  part  of  the 
author,  and  is  one  of  the  most  valuable  analytical  works  which  has 
been  published.  The  only  suggestion  which  might  be  made,  and 
yet  no  doubt  the  author  has  considered  the  advisability  of  it,  would 
be  to  give  more  than  one  test  as  a  generic  test.  For  instance,  under 
carbohydrates  the  Molisch  color  reaction  with  a-naphthol  alone  is 
given.  If  instead  of  a-naphthol  a  solution  of  thymol  is  used  in  con- 
junction with  sulphuric  acid,  a  reddish  colored  solution  results 
instead  of  a  blue  color.  Both  of  these  reactions  are  very  sensitive 
and  characteristic  for  carbohydrates.

It  was  with  a  shock  of  surprise  as  well  as  with  deep  regret  that  I 
read  in  the  Detroit  morning  paper  of  March  2,  1904,  the  announce- 
ment ot  the  death  of  J.  B.  Nagelvoort.  Only  a  few  days  before  I 
had  received  from  him  a  letter,  dated  February  22d,  which  showed 
no  indication  of  any  decline  in  his  bodily  or  mental  powers.  It 
related  to  the  subject  of  some  researches  he  was  carrying  on,  and 
enclosed  photographs  of  plants  of  Hyoscyamus  niger  in  exchange 
for  some  I  had  offered  to  send  him  of  some  of  the  wild  plants  of 
that  species  at  Mackinac.    After  signing  his  name  with  free,  firm
