PREPARATION  OF  BORNEOL  FROM  SYNTHETIC  PINENE. 
By  John  William  Schempf. 
After  detailing  the  work  of  Bertram  and  others  in  this  line  of  investigation, 
the  author  supplemented  their  results  by  an  account  of  his  own  study  of  the 
action  of  Bertram's  reagent  (acetic  acid  and  50  per  cent,  sulphuric  acid)  on  syn- 
thetic pinene.  He  succeeded  in  separating  considerable  quantities  of  borneol, 
one  lot  having  a  melting-point  of  1980  to  1990,  and  another  melting  at  1950  to 
1970.    The  product  in  both  cases  was  optically  inactive.

VALUATION  OF  WILD  CHERRY  BARK. 
By  A.  B.  Stevens. 
During  the  past  year,  as  a  continuation  of  a  paper  read  at  the  Denver  meet- 
ing, he  had  made  comparative  studies  of  several  methods  of  estimating  the 
amount  of  hydrocyanic  acid  obtainable  from  wild  cherry  bark.  Having  found 
that  the  addition  of  sodium  chloride  tp  the  distillate  before  titration  of  it  with 
silver  nitrate,  as  proposed  by  Dr.  Dohme,  made  no  difference  in  the  results, 
the  author  disproved  of  such  addition.  His  results  pointed  to  the  fact  that 
wild  cherry  bark  decreases  in  strength  when  kept  in  stock.  In  accordance 
with  his  results,  published  on  p.  482,  of  this  Journal,,  for  1895,  he  found  that 
the  green  bark  yields  the  least  hydrocyanic  acid,  the  bark  of  the  twigs  more, 
and  the  bark  of  the  trunk  the  greatest  amount.  Mr.  H.  K.  Mulford  then  read 
an  account  of  the  preparation  of  "  Antitoxin  "  for  diphtheria.

In  his  prefatory  remarks  the  author  stated  that  "  several  queries  in  relation 
to  various  individual  food  preparations  have  been  answered  by  papers  read 
before  the  Association  during  the  past  three  or  four  years,"  and  that  "  it  is  the 
purpose  of  this  paper  to  set  forth  some  general  principles  regarding  the  class 
of  substances  which,  in  the  hands  of  physicians  to-day,  are  truly  remedial 
agents  and  perform  this  function."  Secretary  Alpers  then  read  the  following
