strength,  phenol  coming  next,  which  is  followed  by  butyric,  then  lactic,  and  finally 
boracic  acid  5  the  latter  is  so  weak  that  4  per  cent,  is  often  not  sufficient  to  prevent 
decay  of  pancreas — the  latter  always  decays  sooner  than  meat.  Mould  ^vegetation  is 
not  prevented  by  0*5  per  cent,  sulphuric,  1  per  cent,  phosphoric,  and  2  or  even  4 
per  cent,  lactic  acid. 
Dr.  G.  Glaser  claims  that  aluminium  acetate  is  fully  as  efficient  an  antiseptic  as 
acetic  acid,  which  induces  Stein  to  believe  that  soluble  acid  salts  possess  almost  as 
strong  antiseptic  properties  as  the  acids. — Sch<w.  Wochenschr.  f.  Pharm.,  Aug.  8,,

Good  transparent  glycerin  soap  is  made  by  melting  together  10  kilogram* 
tallow,  10  kilograms  cocoa  oil,  6  kilograms  castor  oil  and  10  kilograms  glycerin, 
heating  to  60  or  65°R.,  adding  13  kilograms  soda  lye  (40  per  cent.)  and  12  kilo- 
grams 96  per  cent,  alcohol,  and  stirring  the  mixture  until  the  soap  becomes  trans- 
parent, when  a  sugar  solution  (2  kilograms  sugar  boiled  with  one-half  kilogram 
water),  100 -grams  cassia  oil  and  50  grams  bergamot  oil  are  added,  and  the  finished 
soap  is  poured  into  tin  moulds. — Pharm.  Ztschr.f.  Russl.,  July  15,  1879,  p.  440,  from*

Mouldy  and  unclean  barrels  can  be  readily  cleaned  by  first  rinsing  them  with 
water  containg  soda,  then  filling  them  with  water,  acidulated  slightly  with  hydro- 
chloric acid,  allowing  them  to  stand  two  days,  emptying  them  and  finally  rinsing 
with  clean  water. — Ibid.,  p.  441,  from  Drog.  Ztg. 
Rust  is  readily  removed  from  white  goods  by  soaking  the  stains  in  a  weak, 
solution  of  tin  chloride,  and  rinsing  immediately  with  much  water;  the  tin  salt  is 
more  reliable  in  removing  iron  rust,  and  quicker  in  its  action  than  oxalic  acid,  unless- 
the  stains  are  soaked  in  a  solution  of  the  latter,  contained  in  a  tin  spoon,  when  the- 
stains  disappear  in  a  shorter  time. — Pharm.  Centralhl.,  July  17,  1879,  P»  288,  from.

Extractum  Cinchonae  Fluidum  and  Solidum. — Prof.  Husemann  approves  of  Dr.. 
De  Vrij's  method  of  making  these  preparations,  which  consists  in  triturating  the 
finely-powdered  bark  of  cinchona  succirubra  indica  into  a  thin  paste  with  cold  water 
adding  sufficient  normal  hydrochloric  acid  (20  cc.  to  3  2  grams  total  alkaloids  con- 
tained in  the  bark),  allowing  to  stand  for  at  least  12  hours,  stirring  occasionally, 
transferring  to  a  percolator,  collecting  the  percolate  as  soon  as  it  drops  clear  and  as  long: 
as  it  is  rendered  cloudy  by  caustic  ammonia,  and  concentrating  on  a  water-bath  until 
1  ounce  of  the  fluid  extract  represents  1  ounce  of  bark.  The  solid  extract  is  obtained 
by  continuing  to  evaporate  to  the  consistence  of  a  soft  pill  mass,  42  per  cent,  of 
which  were  obtained  as  a  yield  by  Nanning.  Husemann  claims  that  this  extract  is. 
preferable  to  the  alcoholic,  which  also  contains  all  efficacious  constituents  of  East 
India  cinchona,  but  besides  substances  like  cinchocerin,  which  render  it  partially 
"insoluble  in  water. — Ztschr,  d.  Allg.  Oest.  Ap.  Ver.,  July  20,  1879,  p.  3,21,  from,
