two,  but  can  be  made,  if  required,  of  the  dimensions  of  the  largest  plate 
glass.  These  sheets,  moistened  with  a  solution  of  gelatine,  may  be  stuck 
on  the  panes  of  a  window,  and  thus  change  the  light  admitted  to  any  re- 
quired color.  A  green  light,  falling  on  the  white  silk  made  up  by  dress- 
makers, deprives  it  of  all  its  painful  glare  :  and  in  the  same  way,  yellow 
silk  is  made  to  appear  green  by  a  blue  light,  as  has  been  proved  by  actual 
experiment,  and  it  is  attended  with  the  happiest  results.  Jewellers  who 
have  tried  the  green  paper,  say  that,  when  once  accustomed  to  working  in 
a  colored  light,  they  find  it  greatly  relieves  their  eyes.  In  reading,  top,  a 
sheet  of  the  green  paper  laid  on  the  page  preserves  weak  eyes  from  being 
injured  by  the  strong  contrast  of  black  and  white,  and  enables  many  to  read 
with  comfort  who  have  been  hitherto  obliged  by  too  susceptible  vision  to 
abstain  from  books.  Other  applications  of  gelatine  paper  naturally  suggest 
themselves;  it  may  be  used  as  screens  and  shades  for  many  purposes;  the 
glasses  of  spectacles  may  be  coated  with  it ;  gardeners  may  use  it  in  their 
conservatories;  and  the  yellow  will  probably  be  taken  into  their  service  by 
photographers.  By  the  addition  of  a  small  quantity  of  acetate  of  alumina 
during  the  process  of  manufacture,  the  gelatine  paper  becomes  wTater-proof, 
just  as  linen  or  woollen  cloth  is  rendered  water-proof  by  the  same  chemical 
substance. — Med.  Times  and  Gazette.  January  6,  1855,  from  Chambers1  Jour-

On  the  Fluid  Extract  of  Scutellaria  Lateriflora.  By  Joseph  Bates,  M.  D. — 
Lately  I  have  -been  using  Tilden's  fluid  extract  of  Scutellaria,  with 
signal  success,  in  the  treatment  of  diseases  attended  wTith  nervous  irritation 
and  irritability,  restlessness,  &c.  In  the  treatment  of  children,  it  is  inva- 
luable for  allaying  these  symptoms.  The  dose  is  a  teaspoonful,  repeated  as 
often  as  the  circumstances  for  indications  require.  It  may  be  relied  upon 
in  some  forms  of  hysteria.  Patients  convalescing  from  typhoid  fevers, 
pneumonitis,  arthritis,  &c,  or  any  disease  with  those  symptoms,  will  be 
shortly  relieved  by  one  or  two  teaspoonfuls  of  this  preparation.  I  have  ro 
hesitation  in  saying  that  those  who  give  it  a  fair  trial  will  find  it  efficient 
in  the  treatment  of  many  diseases  for  the  relief  of  which  small  doses  of 
opium  are  frequently  given,  without  any  of  its  unpleasant  sequences.  Much 
more  might  be  added  in  bringing  this  subject  before  the  profession,  but  I 
have  already,  doubtless,  trespassed  in  making  my  communication  too  long.
