veins  of  an  old  mangy  dog,  who  was  perfectly  cured  in  lefs  than
a  fortnight  *,  The  blood  of  a  young  dog  was  transfufed  into
one  almoft  blind  -with  age,  and  which,  before,  could  hardly  move :
the  latter  did  in  two  hours  leap  and  frifk  ^  and  yet  the  young  dog,
which  received  in  return  the  blood  of  the  old  or  difteinpered,  felt
no  fort  of  injury  f.  Would  that  the  fame  experiment  could  be
extended  to  the  human  Ipecies !  and,  fhould  the  change  be  ef-
fected on  mind  as  well  as  body,  how  unfpeakable  would  be  the
benefit  to  the  whole  race  I  Not  only  every  loath fome  diforder
would  be  done  away,  but  every  folly,  meannefs,  and  vice,  changed
to  their  oppofite  virtues,  by  a  due  transfufion  of  worthy  plebeian
blood :  and,  what  would  make  the  experiment  more  beautiful,
not  the  left  inconvenience  in  body  or  mind  would  refult  to  the
generous  lender  of  the  uncontaminated  fluid.

Phyficians,  add  — I  reflect  with  pleafure  on  my  frequent  vifits  to
Mr.  George  Edwards,  the  worthy  librarian,  and  very  able  orni-
thologift.  His  works  are  fo  well  known,  and  fo  juftly  efteemed,
as  to  render  any  panegyric  of  mine  fuperfluous.  Notwithftanding
we  were  both  of  a  trade,  we  lived  in  the  moft  perfect  harmony.
I  efteem  his  prefent  to  me,  not  long  before  his  death,  of  feveraJ
of  his  original  drawings  in  Indian  ink,  a  moft  valuable  part  of
my  collection,  as  well  as  a  proof  of  the  friendfhip  of  a  truly^
honeft  man  J.
