OBITUARY. 
N.  Spencer  Thomas,  Ph.G.,  died  suddenly,  at  his  residence,  Elmira,  N.  Y., 
on  the  30th  "day  of  March,  1890.  Mr.  Thomas  was  born  in  the  year  1827,  in 
Bucks  County,  Pennsylvania.  He  entered,  at  an  early  age,  the  retail  drug  store 
of  Robert  Shoemaker,  Philadelphia,  where,  after  a  faithful  service  of  seven 
years  as  an  apprentice,  he  graduated  from  the  Philadelphia  College  of  Pharmacy, 
Class  of  1847.  In  I85o,  he  entered  into  business  as  a  manufacturing  pharma- 
ceutist, establishing  a  laboratory  on  New  Market  and  Canal  Streets,  this  city. 
Por  several  years  he  did  a  prosperous  business,  enlarging  and  improving  his 
quarters  from  time  to  time.  The  loss,  by  fire,  of  his  entire  establishment,  with 
inadequate  insurance,  resulted  in  financial  embarrassment.  Mr.  Thomas 
removed  to  Painted  Post,  N.  Y.,  where  he  established  a  laboratory  for  the 
manufacture  of  Extract  of  Hemlock  for  tanning  purposes.  His  business  grew 
to  large  proportions,  his  manufacture  of  fluid  and  solid  extracts  of  tannin 
barks  meeting  with  ready  sale,  both  in  this  country  and  Europe.  Later,  he 
added  to  his  extracts  the  "Peerless  Dyes,"  of  which  he  was  the  proprietor  at 
the  time  of  his  death.  He  resided  in  Elmira  for  several  years  prior  to  his  death, 
being  regarded  as  one  of  its  most  enterprising  citizens.  S. 
Carl  Jacob  Loewig,  professor  of  chemistry  at  the  University  of  Breslau,  died 
in  that  city,  March  27,  at  the  age  of  87  years.  H&  was  born  at  Kreuzaach  in 
1803,  became  a  pharmacist,  studied  chemistry  at  Heidelberg  under  Gmelin, 
and  at  Berlin  under  Mitscherlich  and  Rose,  was  then  lecturer  on  chemistry  at  the 
University  of  Heidelberg  from  1830  to  1833,  when  he  accepted  a  call  to  the 
chair  of  chemistry  at  the  University  of  Zurich,  and  in  1853,  as  the  successor  of 
Bunsen,  to  the  same  chair  in  Breslau.  He  continued  in  this  position  until 
about  a  year  ago,  at  the  beginning  of  the  n8th  semester  of  his  lectures,  he 
was  injured  by  a  fall  and  incapacitated  for  further  activity  in  scientific  pursuits. 
He  was  the  author  of  a  monograph  on  bromine  (1829)  of  a  chemistry  of 
organic  compounds,  of  outlines  (Grundriss)  of  organic  chemistry,  etc.  He 
analyzed  a  number  of  mineral  waters,  studied  the  influence  of  alkali  metals, 
amalgams,  alkali  sulphides,  acids,  etc.,  upon  alcohols  and  allied  compounds, 
investigated  the  acrid  principle  of  ranunculaceae  "anemonin,"  a  number  of 
volatile  oils,  like  those  of  parsley,  spiraea  ulmaria,  prunus  padus,  etc.,  and 
devoted  much  of  his  time  to  study  of  the  constitution  of  organic  compounds. 
The  volumes  of  this  journal  published  nearly  sixty  years  ago  contain  transla- 
tions of  several  of  his  writings.  The  deceased  was  revered  by  his  numerous 
pupils  for  his  profound  knowledge,  no  less  than  for  his  qualities  as  a  teacher. 
Joseph  Schrenk,  professor  of  pharmacognosy  in  the  New  York  College  of 
Pharmacy,  died  in  Hoboken,  March  10.  He  was  a  native  of  Hungary,  and  in 
this  country  was  connected  with  several  educational  institutions,  since  1881 
with  the  college  named.  He  was  an  active  botanist  and  an  accomplished 
microscopist.
