TLS 890

[AHearer]

The Times site has made a mess of the interactive version of the TLS crossword this week, so before I waste too much time could somebody with a hard copy please let me know
a) whether 10A, 27A, 18D and 19D really are unclued, and if not what are the clues, please?
b) are the clues to 12D and 14D really the same? If not, what is the clue to 12D please?

10a like something .... that has fallen down from the moon (dickens american notes) 8
27a conceivably give dorian a nod for a part in love's labours lost (3,7)
18d a rum sort of hh munro producing thje tale of the genji (8)
19d scott character, author of the antiquary (7)
12d through each ...., eyeless hole (byron childe harold) (4-6)
hope this sorts you out.
