130  Dr.  macbride’s  improved  Method,  See. 
the  bark,  and  makes  it  go  fo  much  farther  than  when 
the  ooze  is  made  only  of  plain  water.  As  a proof  of  this, 
you  may  make  a pretty  ftrong  ooze  from  the  tan  or  fpent 
bark,  which  you  now  confider  as  completely  exhaufted, 
by  infufing  in  it  lime-water. 
Tanners,  as  they  become  acquainted  with  the  new 
method,  will  find  it  perfectly  eafy,  and  may  no  doubt 
make  further  improvements  by  experience.  The  fore- 
going directions  were  found  fufficiently  full  for  enabling 
a gentleman  at  Belfaft  to  carry  on  the  bufinefs  in  an  ex- 
tenfive  way  for  thefe  four  years  paft;  and  it  is  prefumed 
they  will  prove  equally  clear  and  intelligible  to  all  other 
perfons  in  the  tanning  trade.
