ment  and  verified  by  calculation,  as  follows  :  By  trial,  5760 
grs.  of  sugar,  and  3094  grs.  of  water,  gave  a"syrup  having  a 
specific  gravity  of  1-319;  made  from  these  quantities  the  syrup 
weighs  8854  grs.,  and  as  its  specific  gravity  is  1'319 
its  bulk  is  (^)6712«6o;rs.,  subtractina;  from  this  the  bulk  of  the 
water,  we  have  3618-6  grs.,  for  the  bulk  of  the  suo;ar,  or  (?^)

which  represents  the  apparent  specific  gravity  of  sugar  in  this 
solution  occasioned  by  condensation.  In  solutions,  how- 
ever, of  dilferent  densities,  the  condensation  varies,  being 
greater  in  proportion  as  the  quantity  of  sugar  diminishes.  A 
few  results  are  given  below,  taken  from  several  experiments. 
In  a  solution  of  10  per  cent,  of  sugar,  the  apparent  specific 
gravity,  arising  from  a  greater  degree  of  condensation,  equals 
1-613.

The  bulk  of  12  ounces  of  sugar  in  solution  has  been  shown  to 
equal  7-941  fluid  ounces,  it  may  therefore  for  all  practical  pur- 
poses be  considered  that  |  of  its  weight  will  equal  its  bulk  in  fluid 
ounces.  As  the  idea  generally  prevails,  that  half  of  its  weight 
equals  its  bulk,  this  fact  may  be  of  some  importance. 
As  the  above  mentioned  differences  in  the  condensation  of 
sugar  were  ascertained  by  experimenting  with  various  per 
centages,  I  have  collected  these  together  and  formed  the 
following  table  :

*0n  the  preceding  page,  1  lb.  of  sugar  is  shown  to  have  a  bulk  of  8 
fluid  ounces,  while  here  in  solution  it  has  only  7*961  fluid  ounces.
