tied  "  The  Antiseptic  System — a  Treatise  on  Carbolic  Acid  and  its 
Compounds,  etc.,''  by  A.  E.  Sansom,  M.  D.,  of  London,  which  con- 
tains much  useful  information,  relating  not  only  to  the  chemistry  of 
carbolic  acid,  but  to  its  general  employment  in  medicine.  In  the 
appendix  a  series  of  formulae  are  given  as  follows : 
1.  Liquefied  Carbolic  Acid. — A.  Calvert's  purest  (No.  1)  acid,  lique- 
fied by  placing  the  bottle  containing  it  in  hot  water,  9  parts ;  water, 
1  part.    Mix  well. — Calvert. 
B.  Pure  carbolic  acid,  15  parts  ;  alcohol,  1  part.  Mix  well.  This 
keeps  fluid  at  all  ordinary  temperatures. — Author. 
For  many  purposes,  especially  for  dispensing,  it  is  convenient  to 
keep  the  acid  in  a  liquid  form ;  otherwise  the  crystals  must  be  melted 
by  heat  each  time  that  the  acid  is  employed. 
2.  Solution  of  Carbolic  Acid  in  Water. — To  obtain  uniform  solu- 
tion, it  is  better  to  slake  the  carbolic  acid  with  four  times  its  bulk  of 
hot  water,  and  then  to  add  a  sufficiency  of  cold  water ;  or,  the  car- 
bolic acid  may  be  first  mingled  with  alcohol,  which  causes  more  ready 
solubility,  before  the  addition  of  cold  water.  Water  will  not  dissolve 
more  than  one-twentieth  of  its  bulk  of  carbolic  acid. 
3.  Alcoholized  Carbolic  Acid  (Acide  Phenique  Alcoolise). — Alco- 
hol (90°),  crystallized  carbolic  acid,  equal  parts.  Mix,  and  keep  in  a 
well-stoppered  bottle.  Used  for  making  carbolized  solutions,  &c. 
Being  more  fluid  than  carbolic  acid,  it  more  readily  penetrates  the 
tissues.  Useful  in  poisoned  wounds,  for  application  to  small-pox 
pustules,  &c. — Lemaire. 
4.  Etherized  Carbolic  Acid  (Ether  Phenique). — Sulphuric  ether, 
100  parts ;  carbolic  acid,  1  par-t.  Used  for  insufliation  in  catarrh  of 
Eustachian  tube. — Lemaire. 
5.  Carbolized  Vinegar  (Vinaigre  Pheniqud). — Ordinary  vinegar,  4 
parts  ;  carbolic  acid,  1  part.  Mix.  For  use,  instead  of  aromatic  vin- 
egar, as  a  disinfectant,  &c. —  Quesneville. 
6.  Griycerinum  Acidi  Carbolici. — Carbolic  acid,  1  ounce  ;  glycerin, 
4  fluidounces.  Rub  them  together  in  a  mortar  until  the  acid  is  dis- 
solved.— British  Pharmacopoeia.
