"  My  Dear  Sir, — I  was  very  glad  to  find  from  you,  when  I  had  the  pleasure  of
seeing  you  in  London,  that  you  were  interested  commercially  in  Cod  Liver  Oil.  It
was  fitting  that  the  author  of  the  best  analysis  and  investigations  into  the  properties
of  this  Oil  should  himself  be  the  purveyor  of  this  important  medicine.
"  I  feel,  however,  some  diffidence  in  venturing  to  fulfil  your  request  bygivingyou
my  opinion  of  the  quality  of  the  Oil  of  which  you  gave  me  a  sample,  because  I  know
that  no  one  can  be  better,  and  few  so  well,  acquainted  with  the  physical  and  chemical
properties  of  this  medicine  as  yourself,  whom  I  regard  as  the  highest  authority  on
the  subject.
"  I  can,  however,  have  no  hesitation  about  the  propriety  of  responding  to  your
application.  The  Oil  which  you  gave  me  was  of  the  very  finest  quality,  whether
considered  with  reference  to  its  colour,  flavour,  or  chemical  properties  ;  and  I  am
satisfied  that  for  medicinal  purposes  no  finer  Oil  can  be  procured.
"i  With  my  best  wishes  for  your  success,  believe  me,  my  dear  Sir,  to  be  very
faithfully  yours,  "(Signed)  JONATHAN  PEKEIRA.
