lime  (quinatejde  chaux)  combined  with  alcohol ;  and  is  analogous  to  the 
ethereal  bodies  in  general,  volatilizing  like  them. 
Professor  Pignacca  states  in  his  letter  that  he  has  administered  this  fluid 
by  inhalation  to  eight  patients;  seven  of  them  had  tertian  intermittent  fe- 
ver, the  last  neuralgia  of  the  fifth  pair.  The  neuralgia  was  of  an  inter- 
mittent type.  The  remedy  acted  admirably,  both  in  the  cases  of  fever  and 
in  the  case  of  neuralgia. 
The  quantity  of  the  agent  given  is  about  a  scruple  at  a  time,  repeated 
three  or  four  times  a  day.  It  is  administered  in  the  same  manner  as  chlo- 
roform, and  it  produces  sensations  somewhat  similar.- — N.  0.  Medical  News

Composition  for  Dyeing  Cotton  and  Silk  Goods  of  Rose  and  Purple 
Colors.  By  M.  Malegue. — Rose  Color.  Four  ounces  of  ammoniacal  cochi- 
neal are  dissolved  in  a  quart  of  hot-water,  and  the  solution  boiled  for  ten 
minutes,  88  grains  of  salt  of  tin,  140  grains  of  crystals  of  tartar,  1  ounce  of 
saturated  aqueous  solution  of  sulphurous  acid,  and  140  grains  of  solution  of 
tin,  hereafter  described.  The  whole  is  boiled  for  about  half  an  hour,  and 
then  allowed  to  cool  in  a  glass  or  earthenware  vessel,  and  afterwards  de- 
canted into  another  vessel.  Two  ounces  of  the  carmine  of  safranum  (ex- 
tract of  safflower),  are  then  added,  and  well  mixed  with  the  solution.  A 
sufficient  quantity  of  the  composition  is  then  added  to  produce  the  required 
tint  in  the  goods  to  be  dyed. 
Purple  Color. — The  same  process  is  adopted  as  for  rose  color,  with  the 
exception  that  350  grains  of  the  solution  of  tin  are  employed  in  lieu  of  140 
grains,  and  \\  ounces  of  safranum  in  place  of  2  ounces.  After  having 
dyed  a  piece  of  cloth  of  six  or  seven  yards  length,  it  is  advantageous  to  add 
about  half  an  ounce  of  the  extract  of  safflower. 
The  4  ounces  of  ammoniacal  cochineal  in  the  above  compositions  may 
be  replaced  by  3  ounces  of  ammoniacal  cochineal,  and  3  ounces  of  raw  co- 
chineal. These  two  solutions  are  boiled  together  in  the  water  for  two  or 
three  hours,  so  as  to  evaporate  about  one-third  part  of  the  water.  The  other 
ingredients  are  then  added  as  before. 
The  Solution  of  Tin  is  prepared  by  dissolving  5  parts  of  pure  tin  in  a 
mixture  of  5  parts  of  nitric  acid,  and  18  parts  of  hydrochloric  acid,  all 
by  weight. 
The  Salt  of  Tin  is  prepared  by  dissolving  pure  tin  filings  or  grains  in 
hydrochloric  acid,  to  which  hasvbeen  added  one  fifth  part  of  its  weight  of 
nitric  acid,  and  then  evaporating  the  solution  in  a  water  bath,  until  the 
salt  of  tin  is  obtained  in  a  solid  state. 
The  Ammoniacal  Cochineal  is  prepared  by  boiling  finely-ground 
cochineal  in  twice  its  weight  of  solution  of  ammonia,  for  several  hours. 
The  mixture  should  be  well  stirred,  and  when  it  becomes  thick  it  is 
pla(ed  upon  a  cloth,  which  is  stretched  on  a  piece  of  wicker-work, 
and  placed  in  the  stove  to  dry.  The  dried  mass  is  then  cut  or  broken 
into  pieces, — Annals  of  Pharmacy,  Nov.  2854.
