GLEANINGS  FROM  THE  GERMAN  JOURNALS. 
Analysis  of  Canary  Seed. — Jos.  Hanamann  found  in  the 
dry  seed  of  Phalaris  canariensis  fat  5-30,  resin  and  extractive 
542,  dextrin  and  sugar  2-44,  starch  54-45,  protein  compounds 
18-75,  cellulose  9-65,  mineral  constituents  5*19  and  traces  of 
citric  and  oxalic  acids.  The  air  dry  seeds  contained  11-5 
per  cent,  moisture.  The  ashes  yielded  61*63  silicic  acid,  24-304 
phosphoric  acid,  traces  of  sulphuric  acid  and  chlorine,  4-793 
potassa,  3-043  soda,  3-749  magnesia,  1-459  lime,  -144  alumina, 
°273  ferric  oxide  and  a  trace  of  manganium — (Wittst.  Viert. 
Schr.  1864,  517—522.) 
Persian  Insect  Powder. — Heller  and  Kletzinsky  stated  in 
1856,  that  the  floral  heads  of  Pyrethrum  carneum,  (roseum 
caucasicum,)  which  had  been  collected  on  Caucasus,  contained 
a  volatile  oil  and  santonin  as  active  principles,  but  no  narcotic 
poison  or  alkaloid.  Jos.  Hanamann,  corroborates  this  state- 
ment except  for  santonin  which  he  could  not  detect;  the  volatile 
oil,  separated  from  the  distillate  by  means  of  ether,  is  of  a 
pale  yellow  color,  faint  aromatic  taste,  but  strong  penetrating 
odor  resembling  fresh  chamomile  flowers,  it  stupefies  and  kills 
insects.—(Ibid.  522—525.) 
Solubility  of  Alumina  in  Ammonia. — Jos.  Hanamann  has 
observed  that  18752  parts  of  ammoniawater  of  3*93  per  cent, 
dissolves  one  part  of  alumina  recently  precipitated,  but  that  the 
presence  of  chloride  of  ammonium  decreases  this  solubility 
materially  (Ibid.  527.) 
The  berries  of  Viburnum  Lantana,  have  been  subjected  to 
a  proximate  analysis  by  J.  B.  Enz,  who  obtained  tannin  color- 
ing ferric  salts  dark  green,  valerianic,  acetic  and  tartaric  acids, 
yellow  amorphous  and  hygroscopic  bitter  principle,  acrid  prin- 
ciple, red  coloring  matter,  sugar,  gum,  fixed  oil,  wax,  and 
chlorophyll  (Ibid.  528—535.) 
Thallium. — The  so-called  "ice-salt"  from  Nauheim,  Hessia, 
is  a  mixture  of  salts,  obtained  during  the  winter  from  the  resi- 
duary motherliquor  of  table  salt,  and  is  frequently  employed 
by  confectioners  for  refrigerating  mixtures.  Professor  E-. 
Boettger's  analysis  proves  it  to  consist  chiefly  of  the  chlorides 
of  potassium  and  magnesium,  intermixed  with  some  chloride  of 
sodium,  also  with  thallium,  csssium  and  rubidium  in  the  form  of
