mer,  because  it  fell  through  the  water  to  the  bottom  of  the  receiver, 
whence  being  taken  out  (and  partly  even  whilst  it  stay'd  there), 
it  appeared  by  several  effects  and  other  phenomena  to  be  such 
kind  of  substance  as  we  desired  and  expected." 
Hanckwitz,  the  servant  of  Boyle,  and  working  under  his  direc- 
tion, at  the  laboratory  in  Southampton  Street,  London,  succeed- 
ed, by  his  own  skill  and  perseverance,  in  considerably  improving 
the  process  or  manufacture,  and  produced  phosphorus  in  larger 
quantities  than  any  other  person.  He  confirmed  the  opinion  of 
his  master,  that  it  required  an  intense  heat  for  its  extraction  ; 
he  states,  "  for  in  truth  and  fact  it  is  not  a  work  for  gentlemen 
and  cabinet  chymists,  but  there  is  required  for  it  an  operator 
well  versed  in  fires,  to  whom  its  mechanick  and  manipulation  is 
well  known."  In  an  advertisment  he  states  : — "  For  the  infor- 
mation of  the  curious,  he  is  the  only  one  in  London  who  makes 
inflammable  phosphorus  which  can  be  preserved  in  water.  Phos- 
phorus of  Bolognian  stone,  flowers  of  phosphorus,  black  phos- 
phorus, and  that  made  with  acid  oil,  and  other  varieties.  All 
unadulterated  ;  every  description  of  good  drugs.  He  sells  whole- 
sale and  retail.  N.  B.  He  sells  solid  phosphorus,  wholesale, 
fifty  shillings  an  ounce,  and  retail  three  pounds  sterling  the 
ounce." 
In  a  "  Historical  Sketch  of  the  Progress  of  Pharmacy  in  Great 
Britain,  by  Jacob  Bell,"  it  is  stated,  that  "  a  house  and  shop  with  a 
laboratory,  were  built  on  the  Bedford  estate,  in  the  year  1706, 
by  Ambrose  Godfrey  Hanckwitz,  who  had  carried  on  business  as 
a  chymist  in  the  neighborhood  since  1680.  He  was  a  maker 
of  phosphorus  and  other  chemicals,  which  were  rare  at  that 
period,  and  which  he  sold  in  different  parts  of  the  country  dur- 
ing his  travels.  His  laboratory  was  a  fashionable  resort  in  the 
afternoon  on  certain  occasions,  when  he  performed  popular  ex- 
periments for  the  amusement  of  his  friends.  It  opened  with 
glass  doors  into  a  garden,  which  extended  as  far  as  the  Strand, 
but  which  is  now  built  upon.  Four  curious  old  prints  of  the 
laboratory  in  its  former  state  are  in  the  possession  of  its  present 
proprietors,  Messrs.  Godfrey  and  Cooke,  of  Southampton  Street, 
Covent  Garden,  also  a  portrait  of  Ambrose  Godfrey  Hanck- 
witz, engraved  by  George  Vertue  (1718),  which  he  had  distri- 
buted among  his  customers  as  a  keepsake."
