10D Rash on face, evidently sore under nose, but no head cold (3-10)
i-l-o-s-d-r-d.
Looks like ill-considered (rash)
17A Accomplish outstanding undertaking in catch, one bigging up image (8,9)
o-e-h-a-p-o-e-t-r
must be overhead projector (one bigging up image, and a project is an undertaking)
Beyond this, I can't explain either - any help appreciated
