AVtoberPi894rm'}   Microscopical  Examination  of  Cloves.  483 
I.  A  sample  of  pure  potato-starch  was  examined  and  100  (mm.)2 
was  found  to  contain  (32  +  28  +  32  +  35)  127  starch  grains. 
Another  100  (mm.)2  contained  (32  +  30  +  28  -f-  30)  120  starch 
grains. 
II.  A  sample  of  powdered  cloves  admixed  with  50  per  cent,  of 
potato-starch  yielded  the  following  results  : 
(1)  (14  +  15  +  12  +  15)  56  grains  =  45-34  per  cent. 
(2)  (13  +  .11  +  18  +  13)  55     "     =  44-53  " 
(3)  (17  +       +  16  +  13)  62     »     =  50-20  " 
III.  A  sample  containing  30  per  cent,  of  potato-starch  : 
(1)  (10  -f  10  -f  11  4-  11)  42  grains  =  3400  per  cent. 
(2)  (  7  +  10  +  11  +    8)  36     "      =  29-14  « 
IV.  A  sample  containing  20  per  cent,  of  potato-starch  : 
(1)  (7  +  8  +  7  +  8)  30  grains  =  24-29  per  cent. 
(2)  (7  +  6  +  9  +  9)  3i     "     =  25-10  " 
V.  A  sample  containing  10  per  cent,  potato-starch  : 
(1)  (4  +  2  +  3  +  2)  11  =  8-90  per  cent. 
VI.  A  sample  of  pure  red  cedar  yielded  the  following  : 
(1)  (10  +  10  +  8  +  9)  37  fibres  to  100  (mm.)2. 
VII.  Cloves  containing  20  per  cent,  red  cedar  yielded  : 
(1)  7  =  18-91  per  cent. 
(2)  9  =  24-35  " 
(3)  8  =  21-60  " 
VIII.  Cloves  containing  10  per  cent,  red  cedar  yielded  : 
(1)  4  fibres  =  io-8   per  cent. 
(2)  3     "     —    8-10  " 
All  of  the  above  results  were  obtained  by  using  i^-inch  objective. 
In  the  examination  of  turmeric  ^-inch  objective  was  used. 
IX.  Turmeric  pure  using  one  part  of  water : 
(1)  (11  +  11  +  6  +  5)   33  grains. 
(2)  (  7  +    8+  -6  +  5)   26  » 
Average  X  2  =  118  "
