Vequire  3  pounds  of  residuum  and  2J  or  3  pounds  of  animal  charcoal  for  one  pound 
of  finished  goods  5  2  pounds  of  residuum  will  remain  in  the  charcoal. 
A  paper  on  Oleate  of  mercury  was  read  by  Mr.  N.  Rosenwasser,  in  which  the 
author  advocates  its  preparation  by  combining  5  parts  of  red  mercuric  oxide  with 
13  parts  of  oleic  acid  at  a  temperature  of  22o°F.,  and  diluting  this  to  20  parts  by 
the  addition  of  soft  paraffin,  which  is  stated  to  prevent  oxidation  and  to  materially 
cheapen  the  product.  For  liquid  oleates  paraffin  oil  will  probably  answer  equally 
well. 
Das  Verhalten  der  Bacterien  des  Fleischwassers  gegen  einige  Antiseptica.  Von  Nicolai 
Jalan  de  la  Croix.    Dorpat,  1880.    Pp.  110. 
The  behavior  of  the  bacteria  of  meatinfusion  to  several  antiseptics. 
The  infusion  was  prepared  both  cold  and  at  the  boiling  temperature  and  the 
experiments  made  under  various  conditions,  which  were  alike  in  each  series  for  the 
antiseptics  tried.  The  effectiveness  for  preventing  the  development  of  bacteria  was 
found  to  be  in  the  following  order:  Chlorine  (i  in  30208),  corrosive  sublimate 
{1:25250),  chlorinated  lime  ( i  :  1 1 1 35),  sulphurous  acid  (1:6448),  bromine,  sul- 
phuric acid,  iodine,  aluminium  acetate,  volatile  oil  of  mustard,  benzoic  acid  (i  .  2867), 
sodium  borosalicylate,  picric  acid  (1:2005),  thymol  (1:1340),  salicylic  acid 
(1:1003),  potassium  permanganate,  carbolic  acid  (1:669),  chloroform,  borax, 
alcohol,  eucalyptol.  The  destruction  of  living  bacteria  was  still  effected  by  chlorine 
diluted  to  22768,  but  not  by  corio^ive  sublimate  if  diluted  to  6500  parts. 
Ein  Beitrag  zur  Kenntniss  des  Leuulins,  Triticins  und  Sinistrins.     Von  'Adolf 
Weyher  V,  Reidemeister.    Dorpat,  1880.    Pp.  61. 
A  contribution  to  the  knowledge  of  levulin,  triticin  and  sinistrin. 
Levulin  was  prepared  from  the  tubers  of  Helianthus  tuberosus,  triticin  from  the 
rhizome  of  Triticum  repens,  and  sinistrin  from  squill.  Triticin  is  easily  converted 
into  fruit  sugar,  partly  already  by  boiling  with  water,  while  levulin  and  sinistrin  are 
not  altered  ♦by  heating  their  solutions  in  sealed  glass  tubes  to  loo^C.  On  the  other 
hand,  levulin  ferments  much  more  rapidly  with  yeast  than  triticin  and  sinistrin.  The 
last  two  bodies  have  not  been  obtained  optically  inactive,  but  in  the  purest  state 
attainable  remained  levogyre,  though  in  a  less  degree  than  had  been  previously 
observed  by  others.  Triticin  is  isomeric  with  saccharose,  while  levulin  and  sinis- 
trin belong  to  the  dextrin  group.  Levulin  sugar  and  sinistrin  sugar  are  free  from 
dextrose,  but  rotate  polarized  light  less  than  levulose. 
OBITUARY. 
Mr.  Stephen  E.  Merrihew  died  on  the  ist  of  November,  after  an  illness  of  six 
days.  The  deceased  was  born  at  Marcus  Hook,  Pa.,  in  the  year  1802,  and  removed 
in  early  boyhood  to  the  city  of  Wilmington,  Del.,  where  he  learned  the  business  of 
printer,  and  for  some  years  worked  at  the  trade.  He  then  removed  to  this  city  and 
was  employed  by  Mr.  Jno.  Grigg,  then  largely  interested  in  publishing  medical
