SYRUP  OF  CALCIUM  LACTOPHOSPHATE, 
This  preparation  shows  changes  similar  to  syrup  of  hydriodic  acid, 
gradually  becoming  straw  colored,  which  may  deepen  to  brown  on 
prolonged  standing,  and  not  infrequently  grape  sugar  deposits  may 
be  found. 
The  gradual  inversion  of  the  saccharose  was  observed  in  a  syrup 
prepared  in  midwinter,  the  change  being,  due  to  the  low  tempera- 
ture, somewhat  slow. 
The  syrup  was  prepared  according  to  official  directions,  four  to 
five  hours  being  required  for  completion. 
Immediate  examination  gave  evidence  of  but  a  slight  amount  of 
inverted  sugar,  which  was  not  materially  increased  during  twenty- 
four  hours. 
After  three  days,  however,  2-8  per  cent,  was  found,  after  one  week, 
the  syrup  still  being  kept  at  a  low  temperature,  the  figure  was  4-9 
per  cent,,  which  was  increased  after  sixteen  days  to  127  per  cent. 
Gradual  increases  were  found  at  various  intervals  during  the  follow- 
ing fifteen  days,  and  after  one  month's  standing  20-0  per  cent,  were 
found. 
During  the  following  six  months  the  syrup  retained  its  original 
colorless  condition,  until  the  heat  of  summer  caused  it  to  assume  a 
straw  color,  which  gradually  deepened. 
Examined  after  standing  eight  months,  the  syrup  showed  an 
inverted  sugar  percentage  of  54*9. 
Another  specimen,  prepared  fourteen  days  afterwards,  examined
