In  the  next  place,  as  to  the  relation  of  principal  ^l^'™**^  ^''^
and  agent,  the  same  principles  are  generally  appli-
cable.    Agents  are  not  permitted  to  become  secret
veiidora  or  purchasers  of  property  which  they  are
authorized  to  buy  or  sell  for  their'principals.i  or  ia-^n&'oo^il^^^
deed  to  deal  validly  with  their  principals  in  any  case,  ^^^"irieaifnls
except  where  there  is  the  most  entire  good  faith,  and^Z^tt^l^t
full  disclosure  of  all  facts  and  circumstances,  and  an
absence  of  all  undue  influence,  advantage,  or  impo-
sition.2     And  if  an  agent  employed  to  make  a  pur- ^f^"' aSy"ecret
chase,  purchase  for  himself,  he  will  beheld  a  trustee  S|enJy°™*  °*  "^
for  his  principal.^    Nor  will  an  agent  employed  to
purchase  be  permitted,  unless  by  the  plain  and  ex-
press consent  of  his  principal,  to  make  any  profit
out  of  the  transaction.*

And  the  principles  which  apply  to  trustees,  agents,  (7.)  Miseeua-
and  others,  apply  with  almost  equal  force  to  other  persons.
