Butylhypnal  or  cJiloral-antipyrine  occurs  in  the  form  of  colorless, 
light  crystals,  more  or  less  bulky  according  to  the  degree  of  con- 
centration of  the  mother-liquor.  The  odor  recalls  that  of  butyl- 
chloral,  and  the  taste  is  bitter  and  disagreeable  ;  it  is  very  soluble 
in  hot  water,  alcohol,  ether,  benzin,  and  chloroform.  Its  solution  is 
colored  red  by  perchloride  of  iron  and  yields  an  abundant  precipi- 
tate with  picric  acid.  Under  the  influence  of  alkalis  butylhypnal  is 
decomposed  into  antipyrine,  a) kali  formiate  and  propyl-chloroform. 
It  promptly  reduces  solution  of  permanganate  of  potassium  when 
heated,  and  but  slowly  in  the  cold. — Jour,  de  Pharm.  d'Anvers,

Coryl  is  a  new  anaesthetic  of  considerable  value  in  dentistry 
and  minor  surgery.  It  is  a  mixture  of  methyl  chloride  and  ethyl 
chloride.  Though  it  does  not  produce  as  great  a  cold  as  methyl 
chloride,  it  has  the  advantage  of  being  still  liquid  at  0°,  while  the 
latter  boils  at  —  27 0  C. — Jour,  de  Pharm.  d' Anvers,]zn. ,  1893,  p.  16. 
For  a  local  anesthetic ;  the  venerable  Dr.  Parsons  recommends  the 
following  formula :  Chloroform,  12;  tincture  of  aconite,  12;  tinc- 
ture of  capsicum.  4 ;  tincture  of  pyrethrum,  2  ;  oil  of  cloves,  2  ; 
camphor,  2.  The  camphor  is  first  dissolved  in  the  chloroform,  and 
the  oil  of  cloves  and  the  tinctures  are  then  added. — L  Union

Creolin  pills. — Creolin  is  not  only  used  as  an  external  disinfectant 
but  also  as  an  internal  remedy  in  choleriform  affections.  M.  Hof- 
man  (Jour,  de  Pharm.  d'Anvers,  Nov.,  1892)  recommends  the 
following  formula :  Creolin,  5  gm.,  and  kaolin,  15  gm.;  to  be  divided 
into  100  pills,  and  preserved  in  talc.  This  preparation  forms  a  per- 
fect emulsion  with  water.  The  pills  may  be  coated  with  keratin  to 
prevent  the  evaporation  of  the  creolin ;  but  salol-coating  is  prefer- 
able, as  the  salol  acts  as  an  intestinal  disinfectant.
