I find  in  my  note-book  one  observation  of  a bearing  E.  10°  S.  made  by  me  at  Creadan 
Cove ; it  appears  to  be  the  solitary  representative  observed  by  me  of  the  bearing  rectan- 
gular and  conjugate  to  that  of  C'".  Although  it  is  a single  observation,  I believe  it 
afibrds  evidence  (although  not  strong)  of  the  probable  existence  in  this  district  of  a 
fourth  system  of  forces  having  acted  upon  the  conglomerate  beds.

From  the  preceding  discussion  of  the  planes  of  structure  not  belonging  to  the  two 
principal  conjugate  systems  of  the  district,  I feel  little  hesitation  in  coming  to  the  con- 
clusion that  there  was  at  least  one  more  system  of  forces  at  work,  in  producing  the  final 
structure  of  the  Old  Red  Sandstone  conglomerate  of  the  South  East  of  the  County  of 
Waterford. 
The  bearings  of  this  system  are, 
30°  30'  South  of  East, 
29°  10'  East  of  North. 
There  is  also  evidence,  although  not  so  good,  of  another  conjugate  system,  bearing  9° 
or  10°  East  of  North  and  South  of  East. 
A summary  of  the  four  conjugate  systems  is  here  added,  showing  how  nearly  perpen- 
dicular their  component  bearings  are.  I consider  the  first  system  to  have  acted  first 
on  the  district,  developing  the  greater  part  of  the  cleavage  structure;  and  that  the 
second  system  was  subsequent  to  the  first,  but  probably  produced  by  even  greater  forces ; 
of  the  third  and  fourth  systems  I know  nothing  beyond  their  existence ; the  key  to  them 
may  possibly  be  found  in  other  districts.
