MINUTES  OF  THE 
Friday  Morning — Sixth  Session.    September  8th,  1865. 
The  Association  was  called  to  order  at  8.30  A.M.,  the  President 
in  the  Chair. 
In  the  absence  of  the  Secretary,  Mr.  Wiegand,  the  Chairman  of 
the  Executive  Committee,  was  appointed  Secretary  pro  tern. 
Mr.  Bedford  exhibited  and  explained  various  kinds  of  gas- 
heating  apparatus.  He  stated  that  his  paper  in  answer  to  query 
No.  25  was  not  finished,  and  he  desired  the  privilege  of  finishing 
it  for  publication. 
On  motion  of  the  Chairman  of  the  Business  Committee,  it  was 
resolved,  that  the  paper  of  Mr.  Bedford  be  received  as  if  pre- 
sented, and  that  the  writer  be  allowed  time  to  complete  it  and 
hand  it  in  for  publication. 
Dr.  Squibb  gave  a  short  description  of  a  gas  heating  apparatus 
with  a  fire-clay  lining. 
Prof.  Procter  alluded  to  Bullock  &  Crenshaw's  gas  apparatus, 
used  with  a  fire-clay  cylinder,  and  said  that  they  lay  great  stress 
on  the  value  of  this  clay  cylinder,  which  absorbs  heat  and  gives 
it  out,  tending  to  equalize  the  effects. 
Dr.  Pile  and  others  spoke  on  the  subject. 
The  Business  Committee  stated  that  Dr.  Pile's  paper  and 
specimens  had  arrived,  and  proposed  that  the  latter  be  examined 
by  the  Committee  on  Specimens,  and  be  incorporated  into  their 
report,  which  was  adopted. 
This  Committee,  also,  brought  up  the  subject  of  an  increase  of 
the  annual  contribution  to  three  dollars,  as  unfinished  business 
of  last  year. 
At  the  suggestion  of  A.  B.  Taylor  to  place  an  extra  assessment 
of  one  dollar  for  the  next  year  upon  each  member,  the  Executive 
Committee  presented  the  following: 
"Whereas,  The  expenses  of  the  Association  have  been  greatly 
increased  within  the  past  four  years  through  various  well-known 
circumstances;  therefore,  6 Resolved,  that  an  additional  special 
assessment  of  one  dollar  for  the  year  1866  be  required  from  each 
member,  and  that  the  obligation  to  meet  this  assessment  by  mem- 
bers be  the  same  as  those  which  apply  to  the  annual  dues.'  " 
Considerable  discussion  took  place,  Dr.  Squibb,  Messrs.  Taylor, 
Tufts,  Rittenhouse,  Shinn,  Procter,  Markoe,  Butterworth  and
