Where found (2,4)
I believe the answer is:
in situ
'where found' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for in situ that I've seen before include "Occupying the right position" , "Correctly placed" , "In the proper position" , "In the natural position (Latin)" , "Occupying the original or appropriate position" .)
