The  grains  of  starch  are  quite  small,  not  surpassing  12//.,  and  usu- 
ally lying  between  6  and  9//. 
They  are  simple;  the  gen 
eral  shape  is  spherical,  but  the 
sides  are  more  or  less  flat- 
tened, and  the  grains  mis- 
shapen by  mutual  pressure. 
In  the  starch  from  the  cen- 
tral white  and  mealy  part  of 
the  kernel  of  corn,  the  grains 
have  more  flat  sides,  due  to 
the  greater  pressure ;  while 
in  the  more  hyaline  outer 
part  of  the  kernel,  the  starch 
grains  are  rounder.  There 
are  no  rings  visible.  The 
nucleus  is  central,  and  is  a 
round  point  in  the  fresh  starch  grain,  star-shape  in  that  which  has  been 
dried. 
Corn  starch  is  extensively  sold  under  the  names  of  "  Maizena," 
Maizone,"  as  well  as  that  of  amylum.

ANALYSIS  OF  FACE  LOTIONS. 
BY  GEORGE  JOSEPH   MITSCH,  PH.G. 
[From  an  Inaugural  Essay.) 
The  author  selected  Hagan's  Magnolia  Balm  and  Laird's  Bloom  of 
Youth  for  his  analysis.  Both  are  put  up  in  opaque  white  glass  bottles, 
and  consist  of  a  liquid  precipitating  a  white  sediment  on  standing, 
which  is  readily  suspended  again  on  shaking. 
One  bottle  of  Hagan's  Magnolia  Balm  was  found  to  contain  3J 
iluidounces  of  liquid  and  262  grains  of  insoluble  portion.  The  clear 
filtrate  was  not  acted  upon  by  either  sulphuretted  hydrogen,  sulphhy- 
drate,  carbonate  or  phosphate  of  ammonium,  and  on  evaporation  left 
two  drachms  of  a  syrupy  residue  which  was  proven  to  be  glycerin. 
The  insoluble  powder  was  dissolved  in  hydrochloric  acid  with  effer- 
vescence. The  solution  was  not  precipitated  by  sulphuretted  hydro- 
gen, but  after  having  been  rendered  alkaline  by  ammonia,  with  which
