Observations  on  Blue  Milk.  By  J.  Reiset. — The  disease,  which  is 
presumed  to  be  produced  by  bad  ventilation,  proceeds  from  a  bhie 
fungus,  which  attains  a  length  of  twenty  millimeters,  and  may  be 
suppressed  by  thorough  purification  of  the  vessels  with  boiling  water, 
avoiding  the  use  of  brushes  and  cloths.  Strongly  infected  mil;c  is 
regenerated  by  acetic  acid,  to  which  purpose  an  acid  consisting  of  one 
part  of  water  to  ten  molecules  CJIJJ^  employed,  and  0*5  gram  of 
the  acid  added  to  one  liter  of  milk. — Ibid.,  p.  394,  from  Compt.  rend.,

GLEANINGS  IN  MATERIA  MEDIOA. 
By  The  Editor. 
An  adulteration  of  Senega  Boot,  with  about  15  per  cent,  of  the  root 
of  lonidium  Ipecacuanha  has  been  noticed  in  France  by  Charbonnier. 
The  latter  root,  which  is  one  of  the  so-called  false  ipecacuanhas  of 
Brazil,  is  greyish -white,  in  pieces  about  5  to  6  centimeters  long,  and  of 
the  thickness  of  a  goose  quill ;  it  is  irregularly  undulate,  branched 
below,  and  above  has  small  remnants  of  the  ligneous  stems ;  it  is 
strongly  wrinkled  longitudinally,  and  irregularly  fissured  transversely  ; 
the  bark  is  thin  and  adheres  firmly  to  the  thick  meditullium,  which  is 
of  a  yellowish  color. — Jour.  Phar.  Chim.,  1883,  Jan.,  p.  40. 
Delphinium  Consolida,  Lin. — E.  Masing  obtained  from  5  kilos  of 
the  dried  flowering  herb  about  1  gram  of  alkaloid,  for  which  he  pro- 
poses the  name  calcatripine,  derived  from  flores  calcatripse,  under 
which  name  the  flowers  were  formerly  officinal.  The  alcohol  dissolved 
in  one  thousand  parts  of  acidulated  water,  gave  precipitates  with  the 
various  group  reagents  for  alkaloids ;  tannin  yielded  a  faint  turbidity 
after  24  hours ;  mercuric  chloride,  ammonium  molybdate,  and  potas- 
sium bichromate  had  no  effect.  Sulphuric  acid,  sp.  gr.,  1*84  gave 
a  red  brown  color,  changing  to  violet  brown,  and  after  24  hours  to 
grey-brown.  Fr5hde's  reagent  colored  olive  green,  becoming  gradually 
deeper,  then  fading  to  grey-yellow.  Sugar  and  sulphuric  acid  gave  a 
red-brown  color,  slowly  changing  to  greenish  blue.  Sulphuric  acid 
followed  by  nitric  acid  or  a  nitrate,  causes  the  red-brown  color  to  * 
change  to  orange-red,  then  orange-yellow,  and  finally  golden  yellow. 
The  alkaloid,  which  was  not  quite  pure,  is  soluble  in  alcohol,  ether  and 
•chloroform,  and  appears  to  be  easily  decomposed  by  chemical  agents. —
