598  Practical  Notes  from  Various  Sources.  {AmD^iS.arm" 
without  heat  100  parts  of  cocoanut  oil  or  of  fresh  fat  with  40  parts 
of  solution  of  caustic  potassa  (spec.  grav.  1.145,  containing  15  per  cent. 
KHO),  mixing  intimately  with  30  parts  of  glycerin  and  heating 
carefully.  If  properly  made,  mollin  is  yellowish  white  and  of  a 
smooth  and  soft  consistence,  not  readily  altered  by  exposure,  free 
from  raucidity  and  from  irritating  properties,  and  easily  removed 
from  the  skin  by  warm  or  cold  water. 
Antiseptic  dressings  are  ordered  by  the  German  military  authorities, 
according  to  Phar.  Rundschau,  Prag,  to  be  prepared  as  follows: 
Corrosive  sublimate  gauze. — Dissolve  mercuric  chloride  50  gm.  in 
alcohol  5000  gm.,  and  add  distilled  water  7500,  glycerin  2500  and 
fuchsin  0.5  gm.,  the  latter  being  added  for  the  purpose  of  readily  dis- 
tinguishing the  corrosive  sublimate  gauze  from  others.  Four  hundred 
meters  of  gauze  are  well  kneaded  in  this  solution  and  allowed  to  soak 
for  15  minutes;  the  gauze  is  then  strongly,  pressed  and  well  dried  on 
washlines  being  protected  from  light  and  dust.  It  takes  about  nine 
hours  for  the  complete  drying  of  this  gauze,  but  the  time  may  be 
shortened  by  replacing  the  water  partly  or  wholly  with  alcohol. 
Corrosive  sublimate  cotton. — Absorbent  cotton  is  soaked  in  the 
above  solution  and  dried  in  loose  layers. 
Corrosive  sublimate  catgut. — A  5  per  cent,  aqueous  solution  of  cor- 
rosive sublimate  is  prepared,  in  which  thin  catgut  is  soaked  for  about 
8  hours,  and  the  thicker  kinds  for  10  or  12  hours.  The  catgut  is  sub- 
sequently kept  in  vials  with  alcohol. 
Corrosive  sublimate  silk  is  prepared  by  soaking  well- washed  ligature 
silk  in  a  solution  of  5  parts  of  corrosive  sublimate  in  100  parts  of 
water  and  20  parts  of  glycerin.  After  drying  it  is  wrapped  in  oiled 
silk  or  other  wrater-proof  material;  and  before  using,  it  is  dipped  into 
a  3  per  cent,  phenol  solution,  or  a  one  per  cent  solution  of  corrosive 
sublimate. 
Trichlor phenol  is  said  to  have  been  used  in  Germany  as  a  very  ef- 
fective remedy  in  epidemic  erysipelas.  Its  composition  is  C6H2C13. 
OH,  and  it  is  the  chief  product  of  the  action  of  the  chlorine  upon 
phenol.  It  melts  at  68°C.  (154.4°F.)  and  boils  at  244°C.  (471.2°F.). 
On  studying  the  action  of  alkali  hypochlorites  upon  phenol,  Th. 
Chandelon  observed  (Berichte  D.  Chem.  Ges.  1883,  p.  1749-1753) 
that  orthochlorphenol  is  first  produced  ;  that  on  prolonging  the  action 
two  dichlorphenols  are  formed,  the  orilio-ortho  and  in  larger  quantity 
the  ortho-para  compound;  and  that  finally  the  action  results  in  the
