"I was delighted with him," Appleby said. "He's actually a bit more sprightly, more alert, than he would be at home.
"Being on the track here lights him up a bit more. It just shows his wellbeing.
"For Godolphin, to come over with a live contender is always exciting."
Appleby says Scottish has the right profile to win and doesn't see the 2400m being a concern.
He says Scottish likes to race on the speed and has a strong gallop but importantly believes his form is better than the other international contenders: Sir Isaac Newton, Exospheric and Articus.
"You can tie bits of form in around a few of them and when you do do that he comes out on top," Appleby said. "Some people question about him coming up to the mile-and-a-half again.
"He was beaten by two serious horses back in England there as a 3-year-old in Space Age at Royal Ascot and Highland Reel at Goodwood.
"He wasn't stopping, he was just beaten by a better horse.
"The trip is definitely not a concern of mine."
Appleby says he's not worried about the firm track and believes the 5-year-old has matured and will be suited racing up near the front.
"As a 3-year-old he was a lot keener in his races but now he gets into a nice rhythm," Appleby said.
"His run style is to get him up on the front end and he accelerates well from the front end.
"He doesn't have to be up there, but it simplifies things."
Scottish was the $7.50 third favourite on race eve behind the Ciaron Maher-trained Jameka at $3.50 and Real Love from the Darren Weir stable at $7.
In the latest update, the Herald Sun has reported that Melbourne businessman Lloyd Williams has joined a strengthening Caulfield Cup push for Sir Isaac Newton by buying a share in the Irish raider on race eve.
Already backed from a TAB opening quote of $51 to his current mark of $13, Sir Isaac Newton will carry Williams' navy-and-white colours tomorrow.
A huge admirer of Irish trainer Aidan O'Brien, Williams has bought a string of horses out of the Ballydoyle stables over the years, none more famous than Ascot Gold Cup winner Order Of St George.
His latest purchase - which he will race with his wife Susie and son Nick in partnership with Sue Magnier and Michael Tabor - again impressed in trackwork at Werribee yesterday.
Fellow Cup contenders Articus, Scottish and Exospheric also completed preparations.
Rated inferior to Highland Reel (third in the Cox Plate last year), Sir Isaac Newton has thrived over the past week.
Williams has enjoyed tremendous Melbourne and Sydney Cups success over a long and distinguished career, but his sole Caulfield Cup winner is Faulkner (2013). He is hoping to add to an already imposing record.

The Mick Price-trained 4-year-old will be examined this morning before a decision is made whether he takes his place. The winner of last season's Victoria Derby and Rosehill Guineas, Tarzino is out to $31 yesterday.
