Siegfried gives James a small curved basket, telling him that it contains a cat to be taken to Angus Grier. The basket with which James arrives at Grier's surgery is square and at least twice the size of the first basket. The cat removed from this second basket is extremely large and would not have fitted in the first basket.
When James and Helen return from honeymoon Siegfried tells Tristan to bring the bottle of malt that he has kept for the occasion. A "saved" bottle in such circumstances would be unopened. When the bottle arrives it is three quarters empty.
