ON  CALABRIAN  MANNA  * 
By  Daniel  Han-bury,  F.R.S.,  F.L.S.,  F.C.S. 
Manna,  it  is  stated  in  the  British  Pharmacopceia  (1867),  is  a  con- 
crete saccharine  exudation  from  the  stem  of  Fraxinm  Ornws,  L.,  and! 
F.  rotundifolia,  D.  C,  which  trees  are  cultivated  for  the  purpose  of 
yielding  it  chiefly  in  Calabria  and  Sicily.  Of  the  method  of  collect- 
ing manna  in  Sicily,  there  are  tolerably  exact  accounts ;  and  the 
manna  plantations  of  that  island  have  also  been  fully  described. f 
Having  never  heard  of  manna  plantations  in  Calabria,  nor  seen* 
any  modern  account  of  manna-gathering  in  that  region,  I  wrote  in 
1868  to  my  friend  Colonel  Yule,  of  Palermo,  to  inquire  if  he  could 
furnish  me  with  any  particulars.  Colonel  Yule  being  unable  to  an- 
swer my  questions,  communicated  them  to  Mr.  Grant,  British  Consul 
at  Brindisi,  who,  in  his  turn,  sought  to  obtain  the  desired  information 
from  some  of  the  British  vice-consuls  (Italians)  in  Calabria.  But  ex- 
cept the  statement  that  the  site  of  its  production  was  the  province  of 
Calabria  Citra,  and  especially  the  territory  of  Rossano,  on  the  shores 
of  the  Gulf  of  Taranto,  I  was  unable  to  gain  any  very  precise  knowl- 
edge on  the  subject.
