wax,  yellow  olive  oil  instead  of  bleached  olive  oil.  In  fact,  ex- 
periment has  shown  the  superiority  of  these  bodies  not  meretri- 
ciously tampered  with,  over  the  same  bodies  to  which  a  false 
appearance  of  excellence  had  been  given  by  exposure  to  bleach- 
ing agents,  no  matter  how  simple  and  apparently  harmless 
their  nature. 
The  experiments  on  the  effect  of  temperature  I  have  repeated 
more  than  once.  They  go  to  prove  that  it  is  not  advisable  to 
push  the  heat  beyond  that  of  the  water  bath,  nor  maintain  it 
too  long  at  that  temperature.  I  say  this  feelingly,  as  the  un- 
decisiveness  of  my  first  experiment  and  a  certain  amount  of  be- 
lief in  the  old  wives'  tale  about  boiling  lard,  induced  me  to  try 
the  superheating  process  on  a  large  scale, — and  most  unfortun- 
ate was  the  result. 
I  consider  the  British  Pharmacopoeia  process,  where  the  flare 
is  melted  by  water-bath,  the  fat  strained  from  the  membrane  as 
soon  as  possible,  and  then  dried  by  water-bath,  to  be  an  excellent 
one.  I  would  only  suggest  the  advisability  of  adding  to  it  oil 
of  pimento  or  balsam  of  Peru,  in  the  proportion  of  two  drops 
to  the  ounce,  before  placing  it  in  stock.  Such  addition  does 
not  in  any  way  interfere  with  its  medicinal  use,  and  would  as  I 
have  shown,  much  conduce  to  its  preservation. — Lond.  Pharm.

ON  THE  PHARMACEUTICAL  APPLICATIONS  OF 
GLYCERINE. 
By  Mr.  F.  Baden  Benger. 
Read  at  the  Bath  Meeting  of  the  British  Pharmaceutical  Conference,  Sept.  1864, 
The  Edinburgh  branch  of  the  Pharmaceutical  Society  thought 
proper  to  award  me  the  President's  Prize  for  an  essay  on  this 
subject  a  few  months  since,  and  it  is  from  that  paper  chiefly 
that  I  have  taken  the  following  notes.  It  is  needless  to  detain 
the  Members  of  the  Conference  by  giving  a  detailed  account  of 
the  introduction  of  glycerine  into  pharmacy,  nevertheless  I 
should  like  to  make  a  few  remarks  on  this  part  of  the  subject. 
Glycerine,  as  is  well  known,  was  discovered  by  Scheele  ;  but  I 
find  considerable  discrepancy  in  the  ascribed  dates.    Watts,  in
