Helmont.  His  books  are  for  the  most  part  of  a
medico-chemical  character  ;  he  translated  Crollius'
Basilica  Chemica,  Niirnberg,  1684,  and  wrote  a  kind
of  commentary  on  it :  Konigleicher  Chymischer  uud
Artzneyischer  Palast,  8° ;  edited  works  by  Min-
dererus  Hartmann  and  Ercker,  and  wrote  on  the
plague,  on  medicine,  etc.
The  date  of  his  death  is  not  given,  but  it  may  be
about  1660,  as  has  been  suggested.
According  to  Petrasus,  Cardilucius  was  a  name
assumed  by  JOHANN  HARPRECHT  (q.v.).  The
author  of  the  Beytrag  indulges  in  some  characteristic
raillery  over  the  "master  key"  of  the  "worthy
Kardiluk."

In  the  text  of  the  Bergwerck  .  .  .  biichlin  his
name  is  given  Albertus,  though  it  is  Gilbertus  on
the  title-page.  Albert  us  seems  to  be  a  misprint.
