tracted  some  attention  in  this  country,  inquiries  have  been  directed 
to  us  in  relation  to  the  nature  and  composition  of  this  water.  The 
G-iomale  Italiano  delle  malattie  veneree  e  delle  malettie  delta  pelle, 
edited  by  Dr.  G.  B.  Soresina,  and  published  at  Milan,  contains  in  the 
first  volume  for  1869,  a  paper  by  Dr.  G.  B.  Soresina,  entitled  Le 
aeque  minerali  di  Levico  (nel  Trentina)  ferruginose,  rameiche,  arsen- 
icali,  from  which  we  take  the  following  notes.  • 
The  bathing  establishment  of  Levico  was  erected  in  1860,  though 
the  mineral  springs  had  been  used  for  several  centuries,  and  acquired 
much  reputation  in  Italy  for  the  cure  of  chronic  eruptions  of  the  skin, 
scabies,  rheumatism,  inveterate  arthritis,  &c-  The  spring  of  the  bath- 
ing water  is  in  the  caverna  del  vetriolo,  a  short  distance  from  Levico. 
A  chemical  analysis  has  been  made  of  these  mineral  waters  by  Dr. 
Luigi  Manetti,  professor  of  chemistry  at  the  technical  school  of  Cre- 
mona. The  following  tables  exhibit  the  composition  in  1000  parts  of 
these  mineral  waters,  I  being  the  bathing  water  taken  at  the  caverna 
del  vetriolo ;  II  the  same  water,  taken  at  the  establishment  in  Levico, 
and,  III,  the  acidulous  .drinking  water  from  the  caverna  delUocra  ; 
IV  gives  the  composition  of  ten  grams  of  the  ochre  deposited  from 
the  latter.
