At  102°  C,  boiling  for  fifteen  minutes,  dissolves  0796  parts, 
and  boiling  for  thirty  minutes,  dissolves  '955  parts  of  the  salt. 
According  to  the  theory  of  the  writer,  since  the  solubility  of  the 
lithium  compound  diminishes  with  the  increment  of  heat  to 
100°  C,  and  then  increases,  he  believes  this  increment  to  be  due 
to  the  formation  of  a  basic  salt  less  soluble  in  cold  than  in  hot 
water. 
Ferro  Pagliari. — Dr.  L.  Vinni,  in  Z'Oros/,  Sept.  1885,  states  that 
the  "Ferro  Pagliari"  so  largely  used  at  present  in  Italy,  is,  physi- 
cally, a  limpid,  transparent  liquid,  of  clear,  greenish  color,  inodorous, 
styptic,  and  acid  in  reaction  and  taste,  even  when  largely  diluted. 
The  solution  has  a  specific  gravity  of  1*050  (Skoda),  and  mixes  with 
watery  and  dilute  alcoholic  liquids  unchanged.  If  a  dilute  solution 
be  treated  with  tannin  or  potassium  ferridcyanide,  the  presence  of  a 
ferrous  salt  is  quickly  evinced,  and  on  the  addition  of  silver  nitrate, 
a  voluminous  precipitate  of  chloride  is  formed.  Preserved  in  en- 
closed vessels  and  exposed  to  the  light,  it  remains  unchanged.  It 
has  been  recently  introduced  extensively  by  Pagliari,  of  Florence, 
already  noted  for  the  well-known  haemostatic  liquid  which  bears  his 
name,  Aqua  Pagliari  (solution  of  alum  and  benzoin,  see  Am.  Joue. 
Phar,  1864,  p.  375).  He  claims  that  it  represents  the  very  best 
form  of  iron  administrable,  and  advises  its  use  in  doses  of  10  drops 
or  14  to  20  drops  a  day,  i.  e.,  half  at  breakfast  and  the  other  half  at 
dinner,  largely  diluted  with  water. 
This  preparation,  without  question,  is  analogous  to  the  "Liquor 
Ferri  Chlorati  (s.  muriatici  oxydulati)"  of  the  former  German 
Pharmacopoeia  (see  National  Dispensatory,  third  edition,  p.  676), 
which  is  made  by  adding  520  parts  of  hydrochloric  acid  to  1 10  parts 
of  iron-wire,  allowing  chemical  reaction  to  ensue ;  heating,  however, 
toward  the  end,  to  facilitate  the  emission  of  hydrogen.  Then  rapidly 
filter  and  to  the  filtrate,  after  the  addition  of  1  part  hydrochloric 
acid,  add  sufficient  distilled  water  to  make  the  finished  product 
weigh  1,000  parts. 
Analysis  of  Male  Fern. — G.  Daccomo  (Annali  di  Chim.  Med.-Farm., 
Jan.  1886,  p.  19)  has  subjected  to  fresh  chemical  study,  the  rhizome 
of  Aspidium  Filix-mas,  limiting  himself,  for  the  present,  to  the  con- 
sideration of  the  chemical  nature  of  the  ethereal  extract.  Thirty 
kilograms  of  material  were  exhausted  with  ethylic  ether,  in  a  perco- 
lator, and  after  spontaneous  evaporation,  left  1,750  grams  of  ethereal
