skin  quite  hairless.  Independently  of  its  use  in  removing  abnormal  vil- 
losity,  it  is  of  great  serivce  in  preparing  hairy  parts  for  blisters  or  opera- 
tions. 
It  is  applicable  to  the  most  delicate  or  irregular  surfaces  of  whatever  ex- 
tent, the  hair  re-appearing  only  after  several  days. —  Georgia  Blister  and

On  the  action  of  Citric,  Tartaric,  and  Oxalic  Acids  on  Cotton  ond  Flax 
Fibres  under  the  Influence  of  Dry  Heat  and  Pressure  of  Steam.  By  Pro- 
fessor Calvert. — The  author  observed  that,  when  2  to  4  parts  of  these 
acids  are  dissolved  in  100  parts  of  water,  and  linen  or  cotton  dipped  into 
the  solution  obtained,  and  afterwards  dried  in  the  air,  they,  on  exposure 
to  certain  temperatures,  completely  destroy  the  tenacity  of  the  fibre.  This 
action  of  organic  acids  is  interesting  when  it  is  known  that  it  takes  place 
even  at  the  low  temperature  of  180°,  212°,  and  260°  F.  He  also  found  that 
cotton  and  flax  fibres,  when  prepared  as  above  and  then  submitted  to  the 
influence  of  steam  of  3  lbs.  pressure,  were  destroyed. — Athenceum. 
Quinic  Ether. — A  discovery  which  has  lately  been  made  in  Italy,  and 
which  has  excited  much  attention,  is  illustrative  of  the  results  of  persever- 
ance and  industry. 
In  the  month  of  June,  1852,  a  young  man,  M.  Louis  Manetti,  a  student 
of  the  University  of  Paris,  happened  to  witness  the  death  of  a  patient  with 
congestive  fever,  who  died  apparently  from  the  impossibility  of  introducing 
into  the  system,  in  a  short  time,  a  sufficient  quantity  of  quinine.  Manetti 
was  struck  with  the  idea  that  the  principle  of  the  bark  might  be  effectually 
administered  through  the  medium  of  pulmonary  absorption.  Encouraged 
by  Professor  Pignacca,  Manetti  began  a  series  of  investigations,  the  results 
of  which  are  detailed  in  a  letter  from  Prof.  Pignacca  to  Dr.  Stambio  of 
Milan,  a  translation  of  which  is  found  in  the  "  Annales  de  la  Societe  Me- 
dicale  de  Grande." 
Professor  Pignacca  has  called  the  new  agent  for  inhalation,  Quinic  Ether, 
probably  for  want  of  abetter  name,  for  it  is  not,  properly  speaking,  an  ether, 
and  its  positive  chemical  composition  is  not  known.  It  is  a  liquid  of  a 
special  inconstant  odor,  and  is  obtained  by  the  distillation  of  quinate  of
