OBITUARY. 
Professor  Thomas  Graham,  Master  of  the  Mint,  died  on  the  17th  of 
September,  at  London,  in  his  64th  year,  having  been  born  in  Glasgow  on 
the  21st  of  December,  1805.  His  education  commenced  in  Glasgow,  was 
concluded  in  Edinburg.  He  lectured  for  several  years  on  chemistry  in 
his  native  city,  at  the  Andersonian  Institution.  In  1847  he  succeeded 
Dr.  Edward  Turner,  at  University  College,  London,  and  he  continued  to 
hold  this  appointment  until  1855,  when  he  was  appointed  Master  of  the 
Mint  in  place  of  Sir  John  F.  W.  Herschel,  resigned.  Prof.  Graham  took 
an  active  part  in  the  establishment  of  the  Chemical  Society  "of  London 
in  1840,  and  the  Cavendish  Society  in  1846,  being  president  of  the  latter. 
Prof.  Graham  was  made  a  fellow  of  the  Royal  Society  in  1836,  and  a 
correspondent  of  the  French  Institute  in  1848,  and  received  the  Copley 
Medal  for  his  chemacal  discoveries,  [Pliarm.  Journ).  He  is  best  known 
in  this  country  through  his  excellent  "elements  of  chemistry,"  which 
passed  through  several  editions.  His  recent  experiments  and  specula- 
tions concerning  hydrogenium  exhibit  an  undiminished  intellectual  power, 
the  loss  of  which  to  chemical  science  all  must  regret. 
Peter  Mark  Roget,  M.  D.,  author  of  one  of  the  Bridgewater  treatises  on
