method  for  estimating  the  percentage  contents  of  cinnamic  alde- 
hyde. 
The  cinnamic  aldehydes  have  always  tested  up  well.  There  are 
some  reasons,  however,  for  thinking  that  it  is  not  as  stable  as  the 
oil  itself. 
Extract  of  Meat. 
By  Lyman  F.  Kebler. 
The  author  gives  in  tabular  form  the  results  of  a  chemical  and 
physical  examination  of  a  number  of  samples  of  extract  of  meat. 
These  samples  represent  the  best  grades  as  well  as  the  cheaper 
article,  and  from  the  chemical  analysis  and  other  observations,  it 
would  appear  that  the  price  and  the  quality  are  not  always  con- 
sistent. In  fact,  in  some  cases  there  appear  to  vbe  some  points  in 
favor  of  the  cheaper  product.  Some  of  the  methods  of  analysis 
were  also  touched  upon  and  pointed  out  that  they  are  not  of  very 
great  value  in  certain  cases.  For  example,  one  of  the  points  made 
by  a  certain  analysist  is  the  amount  of  material  soluble  in  80  per 
cent,  alcohol.  Now  it  so  happens  that  common  salt  is  soluble  in 
this  strength  of  alcohol ;  consequently,  the  larger  the  amount  of 
salt  present,  the  greater  the  amount  of  extractive,  which  would 
indicate,  according  to  this  method,  that  the  extract  of  meat  con- 
taining the  largest  amount  of  extractive  is  best.  The  uselessness 
of  such  a  method  is  quite  apparent.
