The  Tea  Tree  in  India. — Mr,  Henry  Mann,  an  enterprising  .gentleman 
who  left  China  about  five  years  ago,  has  introduced  the  tea  tree  to  Southern 
India,  having  formed  a  plantation  on  the  Neilgherries,  which  is  now  flour- 
ishing. The  Madras  Government  has  lately  published  an  interesting  re- 
port upon  the  subject.  The  plantation  is  situated  about  two  miles  and  a 
half  above  Coonoor,  at  an  elevation  of  6000  feet,  with  an  exposure  to  the 
north-east,  and  contains  about  6000  plants.  The  ground  occupied  is  about 
four  acres.  The  plantation  is  on  a  slope.  The  forest  land  is  found  most 
suitable  for  the  plants.  It  now  only  remains  to  test  the  leaf  and  to  pro- 
cure skilled  manufacturers.  This  the  Government  was  asked  to  do  by  the 
Conservator  of  Forests,  but  the  application  has  been  refused  on  the  grounds 
of  the  inexpediency  of  Government  interference  with  private  enterprise. 
The  importation  of  skilled  manufacturers  on  speculation  will  not  probably 
be  ventured  upon  by  any  private  individual  for  many  years.  The  cultiva- 
tion of  tea  in  the  hill  districts  of  India  seems  to  be  spreading  fast,  and  as 
these  are  the  localities  recommended  for  European  colonization,  we  may 
yet  see  India  rivalling  China  in  this  trade,  and  sturdy  Anglo-Saxon  pickers 
depicted  on  the  tea  chests  instead  of  almond-eyed,  long-tailed  men  of 
China. — Ibid. 
A  New  Plaster. —  M.  Pasquier,  of  Roubaix,  has  exhibited  to  the  Academy 
leaves  of  gutta-percha  mixed  with  peroxide  of  iron,  which  he  has  long 
employed  in  the  dressing  of  fractures  and  complicated  wounds.  The  leaves 
soften  in  boiling  water,  and  may  be  then  readily  applied  around  the  limb, 
around  which  they  become  moulded,  and  lose  none  of  their  consistence 
through  the  heat  of  the  body.  After  amputation  he  uses  nothing  but  this 
gutta-percha — neither  charpie,  compress,  or  bandage. — Ibid. 
Production  of  French  Perfumes. — The  chief  places  of  their  production 
are  the  south  of  France  and  Piedmont,  namely,  Montpellier,  Grasse, 
Nismes,  Cannes,  and  Nice  ;  these  two  last,  especially,  are  the  paradise  of 
violets,  and  furnish  a  yearly  produce  of  about  13,000  lb.  of  violet  blossoms. 
Nice  produces  a  harvest  of  100,000  lb.  of  orange  blossoms,  and  Cannes  ao 
much  again,  and  of  a  finer  odor,  500  lb.  of  orange  blossoms  yield  about  2 
lb.  of  pure  Neroly  oil.  At  Cannes  the  acacia  thrives  particularly  well, 
and  produces  yearly  about  9,000  lb.  of  acacia  blossoms.  One  great  per- 
fumery distillery  at  Cannes  uses  yearly  about  140,000  lb.  of  orange  blos- 
soms, 20,0001b.  of  acacia  blossoms  ^Acacia  Farnesiana),  140,0001b.  of  rose 
leaves,  32,000  lb.  of  jessamine  blossoms,  20,000  lb.  of  violets,  and  8,000 
lb,  of  tuberoses,  together  with  a  great  many  other  sweet  herbs.    The  ex-
