The  lectures  in  this  course  will  be  fully  illustrated  and  demonstrations
of  all  the  fundamental  processes  will  be  included.  The  laboratory
will  be  open  daily  (except  Saturday)  from  2  to  5  with  the  exception
of  Tuesday  and  Thursday  4-5,  which  is  reserved  for  lectures.  Students
have  the  privilege  of  taking  Department  cameras  for  outdoor  work
forenoons  and  Saturdays,  when  the  laboratory  is  closed.  Instruction
and  practice  will  be  given  in  exposing,  developing ,  printing  and
mounting .  Also  in  enlarging  from  negatives  or  pictures,  copying
and  photo-micrography.  Special  attention  will  be  given  to  m.aking
lantern  slides  /rotn  negatives  and.  picttires  and  to  the  adjustment  and
use  of  the  projection  lantern.     The  department  equipment  for  this

work  consists  in  part  as  follows  : — Hand  and  view  cameras,  4x5  and
5  X  8,  a  fine  Reflecting  camera  with  Unar  lens  for  very  short  ex-
posures of  moving  objects,  an  enlarging  camera,  with  35x8  Planar
lens,  and  a  Photo- microphotographic  camera  for  enlarging  from
microscope  slides.  For  exposure  in  dark  weather  Cooper  Hewitt
Mercury  Vapor  Lamps  are  used.  Many  other  pieces  of  apparatus
show  the  application  of  photography  in  various  phases  of  scientific
work.
The  natural  beauty  of  the  campus  and  the  surrounding  lake,  hills
and  ravines,  aflFord  ample  scope  for  outdoor  work.  The  opening  of
the  photographic  laboratory  to  summer  students  offers  a  fine  oppor-
tunity to  receive  instruction  in  a  useful  and  delightful  subject  and  at
the  same  time  to  secure  views  making  valuable  reminders  of  their
visit.
