Pancreatic  Meat  Emulsion  has  been  brought  to  the  notice  of  the 
Berlin  Apothecaries'  Society,  by  F.  Riedel,  who  obtained  from  Dr. 
Rosenthal  the  following  formula  for  its  preparation  :  250  grams  of 
finely  scraped  beef  are  triturated  in  a  mortar  with  25  grams  of  pan- 
creatic liquid  (from  the  hog)  and  warm  water,  until  a  homogenous, 
light  reddish  brown  emulsion-like  mixture  results,  which  is  injected 
per  anum  with  some  pressure,  the  bowels  having  been  previously 
cleansed  by  warm  water  injection.  It  is  stated  that  persons  have  thus 
been  nourished,  who  for  months  were  unable  to  swallow  or  digest  food 
taken  in  the  ordinary  way. — Phar.  Zeit.,  No.  18. 
The  Preservation  of  Raw  Meat  is  effected  by  A.  Herzen  by  immers- 
ing it  for  24  or  36  hours  in  a  solution  containing  150  boric  acid,  30 
borax,  15  table  salt  and  5  saltpetre  in  2,000  parts  of  water.  The 
meat  retains  its  fresh  appearance  and  may  afterwards  be  packed  in 
barrels. —  Chem.  Centralbl.,  1876,  No.  15. 
Black  Varnish  for  Leather. — Hager  gives  the  composition  of  a  com- 
mercial article  as  follows  :  30  parts  shellac,  2  p.  mastic,  1  p.  sandarac, 
1  p.  Venice  turpentine,  1  p.  castor  oil,  145  p.  95  per  cent,  alcohol  and 
sufficient  nigrosin  (anilin  black), — Apotheker-Zeit.,  1876,  No.  9. 
Nickelplating. — W.  Baker  and  J.  Unvin  use  the  following  compo- 
sition of  the  solution  :  100  p.  nickel  sulphate,  53  tartaric  acid,  14  caustic 
soda  and  100  parts  of  water. — Ber.  d.  deutsch.  chem.  Ges.,  1876,  109. 
The  bark  of  Rhamnus  Jrangula,  which  has  recently  been  frequently 
recommended  as  a  reliable  cathartic,  has  been  the  subject  of  a  curious 
observation  by  Dr.  Lamm,  of  Stockholm.  Finding  that  a  bark  required 
double  or  even  treble  the  usual  dose,  he  ascertained  that  it  had  been 
recently  collected,  and  in  comparing  it  with  a  bark  known  to  be  three 
or  four  years  old,  obtained  much  better  and  prompter  results  with  the 
latter.  The  inefficacy  of  the  fresh  bark  may  account  for  the  disuse 
into  which  Rhamnus  frangula  has  occasionally  fallen.  Fristedt  men- 
tions (1873)  tnat  tne  recent  Dai"k  produces  colic  and  vomiting,  and  the 
last  edition  of  the  Norwegian  "  Pharmacopoeia  "  requires  the  bark  to 
kept  for  one  year  before  it  is  used  medicinally. — Zeits.  Oesterr.  Apoth. 
Ver.,  1876,  p.  156.
