ON   AN  APPARATUS    FOR  MAKING   SYRUP    BY  THE  COLD 
PROCESS. 
By  Geo.  Macdonald. 
The  question  as  to  the  real  utility  of  what  is  known  as  the  cold 
process"  for  making  simple  syrup,  having  been  considerably  agitated 
in  the  pharmaceutical  journals  of  the  country  during  the  pa?t  3^ear, 
I  wish  to  add  my  testimony  in  its  favor. 
I  have,  during  the  past  ten  years,  made  considerable  quantities  of 
simple  syrup  by  this  method,  and  with  uniformly  good  results.  When 
the  operation  is  properly  conducted,  the  resulting  syrup  is  beauti- 
fully bright,  of  good  density,  and  keeps  well  (much  better  than 
syrups  made  with  heat)  even  during  the  hottest  summer  months.  It 
also  recommends  itself  by  its  convenience,  as  by  its  use  the  applica- 
tion of  heat,  and  the  operations  of  clarifying  and  straining  are  com- 
pletely dispensed  with,  with  the  satisfaction  of  obtaining,  with  all  this 
saving  of  trouble,  a  really  better  product. 
The  apparatus  I  have  been  in  the  habit  of  using  is  quite  cheap, 
and  simple  in  construction,  and  as  I  do  not  think  it  can  easily  be  ex- 
celled for  real  convenience  and  utility,  a  description  of  it  may  be  of 
interest  to  some  readers  of  the  journal.  Before  describing  it,  how- 
ever, I  will  say  that  1  obtained  the  idea  for  the  percolator  from  an 
article  published  ^in  the  "  Druggists'  Circular,"  ten  or  twelve  years 
ago.  Por  the  receiver,  which  embodies  an  application  of  a  well- 
known  natural  principle,  I  claim  for  myself  no  particular  merit. 
The  first  and  most  essential  part  is,  of  course,  the  percolator.  To 
make  this,  take  an  ordinary  iron-bound  ten  gallon  keg,  the  head  of 
which  consists  (preferably)  of  one  piece.  Take  out  the  head  by 
loosening  the  hoops,  and  bore  in  it  with  a  quarter-inch  augur  bit,  as 
many  holes  as  you  possibly  can  without  weakening  it  too  much — one 
inch  apart  is  about  the  proper  distance.    You  now  drop  the  perfor-
