He  made  exhaustive  analyses  of  the  blood  and  urine.  "Prof.  Frick  was  one
of  the  first  in  this  country  to  investigate  the  chemical  changes  produced  in  the
blood  by  disease"  (O.  W.  Holmes,  Trans.  Am.  Med.  Assoc.  1848).  "Im-
portant contributions  relating  to  the  differential  characters  of  remittent  fever
and  its  clinical  history  were  made  by  him  in  1846  ;  our  present  knowledge  of
this  disease  rests  mainly  on  the  facts  contained  in  these  contributions  and
those  of  Stewardson,  Swett,  Anderson,  Stille,  and  Boiling  "  (Flint,  Inter-
7tational  Congress,  1876).  Prof.  L.  P.  Yandell  mentions  Frick's  work  on  Renal
Diseases  as  among  the  ablest  of  the  contributions  made  to  our  literature  by
the  American  profession  [Proceedings  of  same).  (See  addresses  at  memorial
meeting,  March  29th,  i860,  by  Drs.  Johnston,  Donaldson,  Steiner  and  Cox.)
