The  decade  immediately  following  their  engagement  in  business 
was  marked  by  an  era  of  remarkable  advance  in  the  manufacturing 
and  mining  industries  of  the  country.  The  practical  application  of 
chemistry  in  these  industries  also  greatly  stimulated  study  and  re- 
search, and  these  young  merchants  found  the  supplying  of  chemi- 
cals and  apparatus  for  laboratory  and  lecture  purposes  a  profitable 
portion  of  their  business. 
During  this  decade,  the  wholesale  drug  department  was  also 
making  rapid  strides.  Philadelphia,  as  the  centre  of  medical  edu- 
cation, attracted  many  students.  As  a  large  proportion  of  these 
came  from  country  districts  where  drug  stores  were  not  convenient, 
it  became  quite  a  custom  for  the  young  physician  before  leaving 
Philadelphia  to  provide  himself  with  an  outfit  of  drugs.  Bullock 
&  Crenshaw  published  sets  of  labels  and  a  price-list  of  outfits  for 
office  practice,  medicine  cases  and  the  old-fashioned  saddle-bag 
medicine  cases  at  that  time  so  much  used  by  the  country  prac- 
titioners. 
They  enjoyed  quite  a  large  trade  in  this  line,  especially  among 
physicians  in  the  Southern  States.  The  Civil  War  destroyed  the 
credit  of  many  of  these  Southern  families,  and  as  a  result  the  firm 
sustained  a  serious  financial  loss. 
In  the  summer  of  1851  Charles  Bullock  made  a  trip  to  Europe, 
sailing  from  Philadelphia  on  one  of  the  Cope  Line  clipper  ships. 
He  visited  and  studied  the  World's  Fair,  then  in  progress  in 
London,  noting  with  interest  all  relating  to  advancements  in  the 
arts  and  sciences.  After  a  tour  through  Great  Britain  and  Ireland, 
he  travelled  on  the  Continent,  visiting  all  the  important  cities.  On 
this  trip  he  acquired  valuable  information  regarding  the  customs, 
methods  of  business  and  manufacture,  and  established  commercial 
relations  for  his  firm  with  many  of  the  prominent  manufacturers  of 
philosophical  apparatus  and  chemicals  for  technical  and  laboratory 
work.  He  returned  to  New  York  on  one  of  the  Collins  Line  steam- 
ships, the  "  Humboldt,"  in  the  autumn  of  1851. 
Bullock  &  Crenshaw  were  the  first  manufacturers  in  Philadelphia 
of  sugar-coated  pills,  and  for  years  did  an  extensive  business  in 
these.1  On  the  introduction  of  fluid  extracts,  they  engaged  in  their 
manufacture,  and  in  each  one  decided  by  experimentation  upon  the 
proper  method  and  correct  menstruum  to  be  used.  Their  line  of 
pharmaceutical  products  included  also  extracts,  syrups,  elixirs  and 
tablets.
