all finished except for 30ac and I find two spellings for this old orkney and manx law - which is considered to be correct today ODAL or UDAL , I'm guessing the former - clue reads
A type of freehold tenure in use in Shetland, Orkney and Manx law (4) _D?L
Chambers gives them as interchangeable, I have also put the former. Could you help with 17a please? Trade name of a selective serotonin (6) P?O?A?. Thanks.
